Bose subwoofer upgrade?

I have an old bose surround system from the late 90's. It does not have a powered subwoofer. I would like to upgrade and get a powered subwoofer, I have the double cube system and I see lots of inexpensive subwoofers, from like the acoustimass 10 series.

Can I upgrade to one of those? I am open to non bose suggestions.

And I know I should get a new system but my 50" plasma TV and my PS3 have set me back, and I cant afford to spend $1000 or more right now on something cool and new.

any ideas? thanks

First, the Acoustimass modules are not subwoofers, far from it. Secondly, each Acoustimass module is specifically tuned for the particular array so using another may not give you any better results, possibly worse. I would suggest looking at true subwoofers. Infinity makes some fine ones, not too costly and would make the cube speakers sound much better. Something like the PS10 or PS12 which can be found on-line at several retailers.

Yes I know the cubes are not a subwoofer. It has a non powered sub woofer, which never really had alot of kick to it.

the room is about 14x20

It is an Acoustimass module, not a subwoofer.

no....really?

this system has a sub woofer, you know the big black rectangular thingy on the floor all my speakers connect to that rumbles during the transformers movie. It is not a powered sub woofer, but I see plenty of newer acoustimass sub woofers from later systems on ebay.

Bose will even tell you the same thing, the big black rectangular thingy as you call it is an Acoustimass module and NOT a subwoofer. They cannot call it that because it is not a subwoofer. It is a pseudo bass box.

Not trying to argue with you, just want to make sure that you have correct information.

The Bose Acoustimass "Bass Module" , consists of three 5.5-inch drivers in a seventh-order band pass configuration. The three-chamber band pass design is the worst of all major bass enclosure types. Its only purpose is to boost decibel output at the expense of accuracy. It does this by burying all speakers within the cabinet in three separate chambers, and using them to drive air out of its port(s). First of all, 5.5-inch drivers are not intended to be used as bass drivers; they are clearly midrange drivers. In fact, Bose doesn't even claim that its "Bass Module" is in fact a subwoofer because they can't! True subwoofers start at 8 inches and taper off at 15 inches in diameter (sometimes you will find 6-inch subwoofers in multimedia computer systems and novelty 18-inch subwoofers, but those are largely non-conventional designs that do not have any advantage over others.)

gawd

what is the purpose of correcting me? OK so the box on the floor that makes rumbles isnt a subwoofer.

Do you have any useful input to my question?

Shard - glad you made it to the forum and I hope you find everything you need but please allow me to make a suggestion- there are many helpful people here who will literally bend over backwards to assist you and with their wealth of information and it may save you much time, money, and frustration. The caveat is that the information presented is intended to be precise and factual and many people pride themselves on that - (Loves2watch has helped me immensely on several occasions and saved me from wasting much $$$). I think you will find criticizing others and complaining when they are trying to make help you understand will not get you as far as patience and appreciation. either way- Good Luck to you.

Look I understand what he was trying to say, and I am sorry for being pissy.

But, we are how many posts into this without any real info? I got my Bose system for free in a contest so I really don't know that much about it, and when I plan on buying something new I won't be buying Bose. Finding out that my subwoofer isn't a subwoofer doesn't help with my post that I want more and deeper bass from my existing system.

If any can help lemme know.

Which is why I posted this first. As I said, don't want to make you angry just trying to help you in knowing all of the facts to assist you in the most informative decision you can make. BTW Yamaha makes some nice subwoofers as well for reasonable prices. I would also recommend a powered subwoofer no matter which brand you choose.

I understand. I am generally kinda frustrated cuz I just dont know much about this system. OK I remember reading somewhere else that the satellite cubes have no protection hence why they are wired thru the module.

Will any Yamaha subwoofer I get work and protect my speakers? I know I cant plug them in directly to the receiver.

The yamaha YST-SW225 looks reasonable wadda u think?

thanks a bunch btw, if you ever need to know anything about photography lemme know

Yes, that Yamaha would be just fine and "protect" your speakers as it has line level inputs.

As for the photography, I have been a professional in that field for over 40 years but thanks for the offer.

shard23,

I have an Acoustimass 10 series 2 sytem hooked up to an Onkyo receiver. I listen to a lot of live music and thought the Bose system fit my needs pretty well. My only complaint was that I had the non-powered bass module and felt the bass wasn't enough for me and you truly aren't using a LFE channel of Dolby Digital 5.1 since there is no sub hooked to that channel. (someone correct me if I am wrong) I bought a Paradigm sub from a friend for cheap and was blown away by the difference in sound. I didn't change anything w/ the Bose set up just added the sub into the "sub pre-out" on my receiver. I now have full control of my sub through the receiver settings and knobs on the back of the sub. It took me a while to get it sounding the way I wanted it but well worth the time and money. I will upgrade one of these days from the Bose but will never get rid of my Paradigm sub.

And when it is time for an upgrade, try Paradigm speakers. If you think you heard a difference when only replacing the sub, just wait and you will be blown away when you hear all that you have been missing.

I like Infinity speakers, but I am not a big fan of their sub-woofers. I own a set of Infinity speakers (360/140/etc...) and have an Infinity PS10 sub-woofer. It lacks depth.

I would get a different sub, maybe a BIC Acoustech H100 or I think even a Polk sub on a budget would do better than the Infinity sub.

personally, I would not bother replacing the BOSE bass module with a sub woofer. For one thing their satellite speakers really don't go down much below 180-200 hz and most subs are not designed to go up that high. Even if you find one which does, that is not the idea of a sub. A sub is meant to add the lower octave of bass to a main speakers having reasonable mid bass response themselves. Above 100hz it is becomes increasingly possible for the human ear detect the sound as coming from the sub rather than from the satellites/mains.

Really, it would probably be better just to listen to a reasonably price sat/sub system. The advantage would be more accurate sound reproduction overall. If your room allows also consider larger tower type speakers with the possibility of adding a sub later.

I have a Bose system similar to what you have. I am new around here and may not be on the right track. But the acoustimass module not being a sub is an important fact to help you out. You wont want to replace the module. It is essentially a crossover to pull the Bass frequencies out of your center main speakers. Without that you probably will fry your bose satellites. You also aren't utilizing a 5.1 system as you are you only have 5 surround as it is only 5 tracks of audio being sent.

what I did is get a sub as your looking for and hook it up to your sub out. I got a fairly cheap sony sub at boscovs back when I got it ( Hey I was only like 17) and it has done me fine ever since. But in the end you will want all your bose that you have and an additional sub.

I actually run bose cubs w/ a standard 12" sub in my gaming rig. You won't fry the cubes if you set up a crossover at the HT receiver. My cross over is as high as I can set it - 160Hz. Since the bottom end of the cubes is 200Hz, I essentially have a freq. gap between 160 and 200Hz where probably no sound is being outputted by the cubes or the sub - but maybe my VCS-10 center is. I'd have to look at the spec.

So in short, you won't necessarily fry your cubes but you might be faced with a less-than-ideal setup if you replace the bass module. I like the idea of using the sub out - I had no access to the bass module so I do without. For gaming, it's fine. I don't ever think about it or feel like I'm really missing anything.

You probably are getting sound in the 160-200 hz region as crossovers roll off the output, they are not a brick wall. So too the speakers can output below that frequency just at reduced volume. So at worst there would be a dip in frequency response in that narrow 160-200 region, not something that I think you could notice per see. It would be more likely that in an AB comparison with full range speakers the system with the BOSE sats would sound more muted in that region, but again it might be hard to tell with such a narrow spectrum.

But still, I don't think much of BOSE sats and there are many inexpensive sats, like POLK and Infinity that would sound much much better with a powered sub.

I don't disagree with you, not one iota. Since I got the sats for free though...:)

I am a really big fan of Atlantic Technology - would lvoe to replace the bose with their 2200 series setup but I have a hard time justifying spending too much money on what is primarily a gaming rig.
