I think that I may have a problem with my subwoofer. I have a Logitech Z-640 5.1 surround system for computer. Untill recently, my subwoofer is doing alot of rattling as if it has been blown up. So, I used a flash light to look threw the screen the best I can. So far that I can see, the material looks perfectly fine. I don't see any holes or tearing. I was thinking that mabie the rattling is being caused by something loose inside. The thing that I hate about this unit is that it looks like I can't take this apart! However, in the back where the electrical and audio connections are made, it looks like there are screws that I can remove to get to there. But see, not sure if that will help me or not.

In your experiance, could a subwoofer tear in the inside only? What do you think could be causing the rattling sound?

Thanks a bunch Nobium!

You have taught me a lot. Because now I know what voice coils look like. But, I am curious as to what the voice coils do? I did not keep the original box, but kept the receipt and warentee information card. I called Best Buy and they said it would have been better if I kept the box, but they said that they should be able to work something out. The trick is, if you still have a warentee, use it. Because as soon as you remove the back panel, you loose the warentee. So therefor, I will take it back and get a replacment.

You seem to have a good understanding of what is inside a speaker. Thumbsup to you!

Terminator,

I have the same system as well.  Do not open the subwoofer if it is still under warranty.  Even if you found the problem and fixed it, the sub is supposed to be in some type of vaccuum housing - you may damage that vaccuum when opening it (I never have so I can't say how easy it is to screw it up).  Best Buy should have no issues for a replacement unit.  Simply get a new box, open it up and take out the sub - then Best Buy can ship it back to Logitech with a defective slip on it.

Good luck - for a small computer sound system, they rock!  One of these days Velodyne will make a sub for computers and then we can truely celebrate high quality sub sound from our games!  Now back to Half Life 2.

I here ya. I have loved this sound system till now. I bought in on the 7th month of 2003. And speaking of Half Life 2, I love that game. You know, is an it amazing how some of us fokes here love computer, games, and OPE all at the same time lol. Thats why we have this community chat forum so I can mix them all together lol.

I haven't heard much luck with Logitech.  I have Microsoft keyboard and mouse.  I was looking for speakers, and choose the Cyber Acoustics CA-3001.  The provide great bass sound, and I only paid $10.00 for them.  They include a Sub-woofer.    What are your reviews with Logitech?  We should have a computer review area here. 

I live by Maximum PC.  They gave this system a Kick Ass reward, but it costs about $200.  The 8" sub doesn't bottom out until near deafening levels.  It is even better than the Klipsch.

Maximum PC is the only mag that will tear a product to pieces, even if the company just bought a 10 page ad spread.  Be advised, this is no "budget mag", with reviewed systems often costing over $5.000.

Well, I took my system back to Best Buy today. Unfortunetly, they do not sell that model of sound system anymore and could not replace it. So, instead, they credited the cost of it plus tax to a Best Buy Gift Card. I was looking at the systems they had there. And was looking at one that costs 200 dollars. A little steap mabie, but it produces way more bass than the other one. I just need to be a little more carful this time. I am going to look it up online to get th tech specs on it. Thanks for your guys help in the matter. Hay Ajace, how is your sound system?

I would like to try my Panasonic 800 watt TV surround sound system on the PC here. The z640's are not my favorite choice of surround sound. They are good to an extent of woofer power and bass quality. I find that as long as you don't put the bass up too high it will be good but it then gets distorted easily on higher volumes. My 900$ surround sound on the other hand has AMAZING sound! i play Bass techno and Blast it loud enough to knock the windows out lol :) the bass is incredible, no distortion even at max, only problem is that it annoys everyone else in the house at that level. The logitech has an 8 inch sub i believe, my panasonic system has a 7 1/2 inch sub with a 340 watt amp. Aluminum cast cone with rubber bushing around it. rear firing and front ported. I sit a foot and a half away from it, KABOOM!

This is what I am looking at now. Its the Logitech Z-5300 This sucker is one of their best models and praduces alot of sound. I should have got this in the beggining.

Mine are bassy, but for ten dollars they are perfect.  Cyber Acoustics CA-3001.  Just them a look and tell me what you think.  http://www.circuitcity.com/ccd/Search.do?c=1&context=&keyword=Cyber+Acoustics&searchSection=All&go.x=15&go.y=9

Terminator, my first post in response to the Z-5300 was deleted by ChrisS, but I'll repost because I think it will help you out.

According to Maximum PC their favorite 5.1 system is the Z-5500, their favorite 4.1 is the Logitech Z-560's.  They were disappointed in the new Logitech 2300's.  Based on your interest in gaming, high quality computer audio and videocards, I'd say you'd love a subscription to Maximum PC.  It's about $10/year.

Good luck,
