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!

Terminator20,

Have you heard of the video cards

XFX - 6800 GT - GEFORCE 6800 GT 256MB? $529.99

Or how about the BFG - 6800 Ultra OC - NVIDIA GeForce 6800 Ultra Memory 256MB (overclocked to run as 512MB) $699.99

I was wondering what your opinion might be as they are both expensive and I am not to sure which would be better for their price

My friend says the BFG is the best out there right now.

Both are sold at www.cas-tech.ca (where I would like our PC to be built from).

From the sounds of it (No pun intended) the sub is fine since it is not constantly running at max, therefore it is probably just a loose screw or something. The amp would look like a cube/rectangle encased in metal or it might just be and open amp with no case (components exposed).

You're right, it is a pretty tight fit so you might have a tough time reaching in but the amp should be bolted to the removable panel or at least close to it.

The system should still be covered by the two year warantee unless you open it up.

The back of the best buy bill/warantee states that as long as you have the bill/proof of purchase they will accept it. ""IF"" you don't have the box or other materials it came with they deduct a small amout from the money you get back or something like that.

There is still that small chance that the sub's "Voice Coils" (Copper wire coils) are rubbing against the magnet. Depending on what the humidity, temperature, and if it has been in the sun it may be damaged,causing the surrounding material holding the sub in place to be worn out causing a rattling sound, ( had the same problem with 20 year old speakers but your sub isn't 20 years old lol ).

Np with the help.

I have the same PC Sound System and have had no problems. The only reasons I can think of that your Sub is Rattling is that:

1. The internal amp may have screws loose.

2. If you were playing sound with loud bass the voice coils might be damaged.

3. The magnet in the back may be loose if improperly constructed.

By Removing the rear panel you may be able to access the inside but at the same time possibly voiding the warranty if you got one.

I highly doubt that the inner material would tear as it is constructed out of a heavy material and could possibly have a steel or aluminum cone (ALLUMINUM-Alumminum??).

What is the volume you play your music at and what level bass-Low/Med/High---

It could just be a defective Sub.
