Scored a pair of series 3.I refoamed all 18 drivers bought a EQ on eBay sent it in for re-cap and upgrade then hooked them up to Pioneer SX 1250.Ha ha heaven. Reviewed Nov 21st, 2018 by Artfrobadoo My buddy has a pair of supposedly original 901s which I have suspicions of being fakes. The wood does not match. There is no labeling. The terminals are crude. He thinks they are the cats meow. So I searched craigslist and I found a pair of 901s for 200 dollars. Then the guy throws in a beautiful working Kenwood KA 7300 amp. I like my Bose 301's better then these 901 VI. Perhaps it's the amp I have the associated speakers to what. Reviewed Nov 02nd, 2018 by OzDaddyBear I have 901 series VI and there i a plug between left and right termina, there is nothing in the manual to advise what this is fot. Any ideas?l Reviewed Jun 12th, 2018 by Mrsteve I have owned two pair of these. The first pair a series IV, the Second pair a Series VI. I took advantage of the Bose Trade-in program some years ago when they still offered it. There are several companies that offer the drivers, and replacing them for both pair is around 560.00-Plus the time involved.I need to do a repair on the equalizer. I cannot find the Series III Service Manual. Thanks To be use for PA system or Karaoke. Any suggestion for an appropriate mixer. I'm looking for resources to help me troubleshoot and repair the equalizer. I don't have much experience, but I would like to learn, and this seems like a fun project. If anyone is willing to help break things down as simple as is convenient, or could help guide me in this process, I would be very grateful. We all have to start somewhere. I refurbished the speakers myself, and would like to say I did the same to the equalizer. Due to purchasing from a second hand store and not really knowing enough about them I consequently now own two right hand speakers. Not sure how this will affect the speakers. While it might well be quite possible to fix, I would be more interested in feeding the speakers from another signal source. The cable from the preamp connects to the speakers via a five-pin 180 degrees DIN plug, and so I think it should be quite possible to connect to some other signal source, the same way I have used a pair of Philips MFB speakers. Am I right or am I right. Anyone have any experience of the 901p active speakers. Or of other Bose Lifestyle 20 substitutes for them? No need to attend a live concert anymore.

The left channel on mine no longer works and I am trying to trouble shoot.I'm also 901 owner. and listener The problem I met was at the first place, the EQ. It's s-IV. They are designed long time ago, before CD and DVD players. And as we know, their output signal is about 2V. EQ s-IV and earlier are designed for tape deck, tuner and turntable signals, which is about 0.5V. The higher signal levels overload the EQ and begin distortions. That's why, if you use players without regulated outputs, or if your receiver or preamp inputs are not attenuated, you'll have problems with the quality of the sound.But you know this very well Lately I use mine with The Bose Spatial Receiver. And even with this old vintage, with dry old capacitors and mash of switches and wires inside, I think, they sound well. And my advice is - don't try to use them without the right EQ. It's waste of time.Btw I think the 901's mid-century modern styling still looks cool, especially the black version and especially when the Bose pedestals are used with them (they were used this way in a cellphone commercial about four years ago, located in a swanky, light-colored modern apartment).OTOH, currently an old vintage speaker as the early series of 901 is much harder to beat than in those days, because the tendency of the sonic quality from today's commercial speakers have become significantly worse, even in the upper price class. Keep this always in mind. I am looking for a diy project with cheap but good quality full range transducers with the same design goals than by the 901, but higher quality.As I recall, they did sound amazing for their size.But for sure, it's not about the price, and for sure results are good By the way, I listen and a pair of 601s s-1, but they are fare from 901s, by my own Resources saved on this page: MySQL 15.79 vBulletin Optimisation provided by.

These items can be very time consuming to do if you are only beginning to learn about breadboards and electronics. The first thing that you need to do is take a moment and realize what you will do. Have you any idea how long you're likely to spend taking notes. If you have a couple straightforward ones like that I do, it can get frustrating especially when I visit a long break and I begin trying to create notes again. So, the first step that you want to do when you're taking your notes is to take a fantastic look in your breadboard. Once you take a good look at it, you can then begin making notes on your breadboard.You want to take off the boards back side to show the aluminum connections. The back side of the breadboard is where you will make the connections to the devices which you need to connect. Have a little time to examine the circuit diagrams for every device. Then you will see why they're getting labeled in the manner they are and why the connections are there. Once you take a look at them you will know why they are getting labeled the manner that they are.When you're acquainted with how to earn a breadboard wiring diagram you will be able to make diagrams out of circuit diagrams. That is precisely what I am hoping to educate you in this report. I expect you will continue to see as I create the rest of the articles easier to know so that you may learn how to make a breadboard wiring diagram. Thank you for reading my posts. For example, if you're thinking that you are doing your own electrical work properly, once you are actually doing this wrong, then what could you consider doing it. Andif you hadn't ever done electrical work before, how do you feel you would manage the situation if you're responsible for doing your own electrical work? If you are working on any electrical function of any sort, it's absolutely essential you understand how to read a home wiring diagram. Without it, you could potentially be doing much more damage than good. There are a range of reasons why you need to understand how to read a house wiring diagram, but the main reason is to do with safety. Safety is not just something that you need to be concerned about when you are doing electrical work around the home. Additionally, it goes for any other sort of work which you might have to do. By way of instance, if you should fix a pc, without understanding how to read a house wiring diagram, then you'd be putting yourself at great danger simply by guessing what was wrong with your pc and then attempting to fix it with no understanding of the ins and outs of computers. There are a lot of reasons why it is very important that you know how to read a home wiring diagram, but security is just one of these. You may also find that knowing how to read a home wiring diagram can help you be certain your job goes smoothly, and you do not get into any dangerous circumstances. Perhaps you have a new job where you need to have access to the electrical wires which run throughout the home. Even if you are the only person who knows how to read a home wiring diagram, you can still do yourself a huge favor by getting a friend or family member to show you the way to do it, so you donot wind up getting hurt when you are attempting to do your work. Another reason you ought to find out how to read a house wiring diagram would be for whatever electrical function. When it comes to a home wiring diagram, a diagram could be equally as crucial as a manual. There are a number of different ways a manual could be misleading, however a house wiring diagram can sometimes be misleading as well. In addition to showing you how to properly run cables throughout the house, a wiring diagram can also show you exactly what you need to be running in certain places. There are lots of cases where a home wiring diagram is referred to as aHow To book. While this can be a fantastic thing for many people, it may also be misleading and leads to the incorrect conclusion. It's a good idea to read several novels which contain a home wiring diagram, before you choose one that you're going to use. If you are interested in learning how to examine a house wiring diagram, then it's a fantastic idea to read a few books that contain the diagrams that you need to understand how to read. There are a number of different books which are available on the topic, and it can be hard to know which ones are going to be great to use. Learning how to read a house wiring diagram can be very simple if you know where to look. The way to insert a Venn Diagram in Google Docs is really a two-step process. The first step is to choose a suitable case for your document, and the next step would be to compose some appropriate content. There are several techniques to select an example that's useful for your own use, such as a CD of color photos, or perhaps your personal images. After you have decided on the case you want, you must identify the record that you need to put it in. It's simple to identify what record is being written about - after you've identified the instance, all you need to do would be to name the record following the example. As you begin writing, you will almost certainly wish to pick keywords that match the case, which should be said in the manuscript. Now you must identify the relevant key terms. You can do this with a free keyword suggestion tool like Google, or with a paid service like AdWords Keyword Research. Either way, be certain you're focused on the topic you are writing about, rather than to be vague about the key words that you want to use. As you are writing the name, description, and keywords, you are going to want to make certain to consider what sort of content you'll be writing on your document. Is your document going to be used for internal use, or will it be utilized by the client. Will the record be in-house, or can it be distributed to clients? Step one involves learning the different kinds of documents, and making certain the author's sense of making a suitable case. As an instance, if you would like to add a Venn Diagram in Google Docs in-house, you will probably have to understand that and you'll have to be sure you provide the case with the right title and content. On the other hand, if you are composing a letter for a client, you might want to offer the customer with a table with the appropriate types of Venn diagrams. The next step involves determining the size of this document, and the number of segments it's. A good example will normally have a great title, and you should be certain the title is unique so that it won't appear in the index of a search. Additionally, you should determine the section sizes, so you will know which one you will use. The next step involves studying the info you'll need to put in your document. By way of instance, if you're looking for a Venn Diagram, then you will have a series of classes to select from. For each category, you should consider how many images you'll need, how many items you'll have to contain, and how many sentences will be required. Finally, you will be able to obtain an notion of how to insert a Venn Diagram from Google Docs simply by going through the cases you've chosen, and record the info on what the product is and where it's found. You can then mark the key phrases and titles you will need to use and make a last draft. Just do not forget that each illustration is unique, so you'll need to learn the key words which are important for that example. Perhaps you have thought about how to generate a fishbone diagram in PowerPoint. This would be great for any demonstration because it would enable you to present your information in a way that individuals can easily follow. 1 good means to do so is using PowerPoint. So how can you use PowerPoint so as to create a diagram in PowerPoint. To be able to make your demonstration work, you would first have to decide on a template. There are various templates which you can choose from so that you should know what type of presentation you want to create before you pick a template. Now you'll have to settle on a presentation. It is also possible to make your own template or you can select a template that already exists in PowerPoint. When you have your presentation ready to go, you'll have to make the necessary modifications to it so that it appears right. You'll have to change the colors, names, and be certain that everything else looks right in your presentation. The following step is to choose the design for your presentation. There are two unique layouts which you could choose from, the left sidebar and the ideal sidebar. The left sidebar will display a lot of information, whereas the ideal sidebar is only going to display the most important part of your presentation. Now you're ready to really produce the diagram in PowerPoint. First, you will have to decide how large you want your diagram to be. Then you will have to put your fishbone diagram on the webpage. When you have highlighted the fishbone diagram, then you'll have to click on theProceed To link to get back to the diagram you were working on. In the end, you will have to click on theOkay button to continue your presentation. Whenever you make a demonstration, it's always wonderful to make the most of the tools that PowerPoint has to offer you. Making a fishbone diagram in PowerPoint is only one instrument which you may use so as to assist you create a demonstration which individuals can follow. The rear grill also works to cut the treble response from the rear drivers. If you try running these speakers without the rear grills expect shrillness on a scale that should not exist in the natural world.The port tube design is something I've never seen duplicated, it makes for a very deep tuning without much physical volume. The downside is that these ports can put a candle out from 6 feet away and are audible at full chuff.It's a pretty stout box if you account for all of the holes in it.The idea is that you hook up your wire and thread it through the speaker stands. Then, unless you want to put wood screws into your speakers to attach the stands, you are in for a chore. The dance of flipping the speaker while trying to hold the stand onto the bottom is a contortion that only the 901 owners can understand.This iconic design is really beautiful, if not the most functional. The wire is supposed to run through the top and out of the bottom, but there is no notch for it to slide under on the bottom. Instead the wire just kind of get smashed and the stand becomes slightly unbalanced.The blue line is for the default Bass EQ, the red line is for the secondary bass setting. Yes, that is a shit ton of treble boost, as well as a healthy chunk of bass boost.Choose up to 15dB variation in the treble tone, and 10dB to the mid-bass. I took over the living room and pushed my main speakers into the corner. I ended up at 16 inches from the rear wall and pushed them a bit wider than my main speakers to give them as much room as possible to operate. Now in a perfect world these would have an uninterrupted wall behind them and closer to corners, but I don't have that option so the right channel is stuck on the hallway side. Originally the 901's were to be setup mostly at ear level when seated. The setup for the past 30 years has been tied to these short stands, or hung from the ceiling far off axis. There is even a recommendation for matching pairs of floor and ceiling 901's in some manuals, something I'm sure a few die hards have tried. I'll break it down the performance of the speaker into a few standard categories and how they perform in comparison to other options out there. After initial placement I never once felt like I needed to move the speakers to get more out of them. Imaging is huge and involved, but it is hard at least in my setup to place or pick out specific elements of the music. There is no denying the 901's ability to make you hear all of the music, but because the image is such a blur I don't seem to notice it as much as directional speakers, it instead you get the feeling of it. In contrast, Linkwitz dipole speakers create a soup of sound spread around the room, where the 901's transform the walls into massive speakers.These are some of the loudest speakers I've used in the 200Hz-10kHz range. Setup outside I was able to blast 112dB of non distorted music out of the back of the speakers measured from 10 feet away. The front was limited to about 98dB, which is still pretty damn loud for outdoors. I can see why there is a version of these speakers for PA use. When you start to get above 95dB the bass response falls off as the little drivers can't play deep bass at high volumes. This can also lead to them falling apart before 95dB on complicated tracks that are also bass heavy. For instance most Chemical brothers tracks are limited to about 85dB just because the full range drivers just can't do everything at once.If you sit and listen critically you will be met with harsh treble and bloated bass. Adjusting the EQ to fix these problems will leave the speakers sounding dull as it turns down all of the treble when the worst problems in the cone breakup range above 5k. Bass response is harder to nail down, it's hard to get away from the muddy bass, and honestly the Bass EQ options seem limited to either bloated bass or no bass.Some simple instrumental tracks sound good, but anything with female vocals or cymbals should be avoided. These speakers can be used in a party scenario, and will impress most drunk people with the quantity of sound they produce.My neighbors had to deal with 95dB sine sweeps for 3 hours straight, and then pink noise for another hour. I think you will find the results are totally worth it though.This the most quiet axis of the speaker, so it's not as important as other measurements, but this is definitely not a good start. We are seeing bass response down into the 30's and a jagged sloping response to the treble and a massive 7kHz peak. The jagged response is probably due to baffle reflections, and comb filtering from the 9 drivers all doing the same thing.It's damn near impossible to make out what is happening here, but generally the response gets much louder as you move around the back of the speaker.On the bottom we have the front power response, this is an average of 0-60 degrees. On the top we are looking at the rear power response, an average from 120-180 degrees. Yes, the rear is about 10dB louder, than the front.It's an average of all of the off axis measurements, or the total power response of the speakers, and it's flat. Normally a power response would be tilted to show a roll off of the treble, but it's hard to say that it's wrong given the strange dispersion pattern. Maybe this was the intended goal of the speaker, or maybe it's just a coincidence.This measurement was taken slightly above the axis of the speaker to better represent the suggested listening height. The red measurement is with the speaker 12 inches from the back wall, and the blue one is 18 inches. These are very similar, with the 12 inch being a little nicer. Also, note that the 7k peak is not hidden by the boundary, rear speaker interaction, or even being off axis vertically.I continued on like this until, finally I ended up cutting everything a little. While it definitely sounds better, the correction is far from perfect due to the inherent irregularity of the speakers response.He went through the trouble of designing excellent five inch whizzer-less full range drivers and stuffed 9 of them in a clever box, While it has plenty of flaws, I respect it's performance, blasting off faces and painting walls with sound in a way that no other speaker can.First priority is to get a subwoofer, crossing over to a sub as high as 90Hz can really clean up the sound of the speakers, and will give even more headroom. The second priority would be to add a dome tweeter to the speaker. A stand alone enclosure that sits on top and crosses over to the 901's around 3k with something like a minidsp would fix all of the cone breakup and much of the comb filtering issues. Doing all of this should still leave most of the imaging tricks intact and while it does add considerable cost, there are worse things to do with your money.Micca COVO-S Review!
