I have a Microsoft System 80 subwoofer unit with a bad (rattling) subwoofer. Since I have not been able (as of yet) to locate a dual voice coil replacement, I'm going to try to replace both the speaker and the passive radiator with two single voice coil subwoofer speakers. Anyone with bad speakers watch for my results in the coming months! This may be a good fix for all those blown units. Next time I won't listen to Deadmau5 too loud or heavy on the bass, either!

check your connections if they are good another problem I could see possibly happening was if the wires for the speakers were plugged into the amp while it was turned on the wires may have touched together and blew the side out of your amplifier.
Very common problem with today's receivers. Receivers made today don't have a true preamp section in the amplifier and do not amplify the sound to the extent of an older receiver. I have large 15" front speakers on my system, and have stuck with my 15 year old receiver just because I know that a new receiver will not have the power to drive them well. Many of the newer receivers need to be turned up to 50-60% before you can even hear anything from the speakers.
The surround sound outputs outputs ic's in the remainder of the system have opened, or there is a short in the speaker wiring, check to make sure that is not the case, if okay! you will need a repairman to assess the situation.
H?, You have a very good system...one of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer. .your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2)..in order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it.. Take care and please Remember to rate/vote and give me 4 Thumbs Up for Helping out the Community :) Hope this helps! -------------------- Additionally please follow the instruction on your user manual to activate the SUB ,as is follows.. ----------------- BASS-OUT
Low-frequency (bass) signals can be directed to the
subwoofer and/or the front left and right speakers
according to the characteristics of your system. This
setting also determines the routing of the LFE (low-
frequency effect) signals found in Dolby Digital or DTS
Choices: SWFR (subwoofer), FRONT, BOTH
• Select SWFR if you connect a subwoofer. LFE and
low-frequency signals from other channels are directed
to the subwoofer according to the speaker settings.
• Select FRONT if you do not use a subwoofer. LFE and
low-frequency signals from other channels are directed
to the front speakers according to the speaker settings
(even if you have previously set the front speakers to
• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to
both the front speakers and subwoofer. LFE and low-
frequency signals from other channels are also directed
to the subwoofer according to the speaker settings. Use
this function to reinforce low-frequency signals using
the subwoofer when playing back sources such as CDs.
It sounds like the driver itself may have violently blown (the rattle). Is the hum from the speaker (amplfied) without input? Probably something in the amp is gone, too. A hands-on tech would be able to diagnose it for you.
The bar speaker system needs to be connected to an amplifier. What the bar speaker does is replicate a five speaker home theater system using just an amplifier.
The only thing that will give you a better sound quality is some type of amplifier/speaker set-up, wether you choose to have an amp and two speakers or and amp with five speakers and a subwoofer is up to you.
As I implied earlier, take a clue from the physical style of connectors for both parts of the subwoofer function in the old and new receivers:
RCA connections are for Line Level signal between components only.
The input (bare wire) at the speaker is for AMPLIFIED signal.
You can't just modify one to fit the other and expect magic to happen. Be glad you didn't do it the other way around and modify an amplified (speaker level) outout into a Line Level input. You likely would have smoked that component.
Your subwoofer is a passive speaker, that is, like any other speaker it needs an amplifier. Many subs are self-powered (amp built-in) and they would mate well with the RCA sub output of the receiver.
Get yourself an Active (self-amplified) Subwoofer and run UN-MODIFIED RCA cables to it, according to its instructions, from the Sub Out of the receiver. Or get an amplifier between your receiver and the sub you have.
just repaired my se 501 poor solder conections on blue rleays by speaker jacks,also blown center speaker seems there are 2 in it one blew and so did cpacitor running now just hooked up one in center speaker sonds great also stay at 8 ohms setting
Go to the following website www.servicemanuals.net where you can get the service manual for $17.00, unbelieveable, don't you think? The service manual should help you sort out your hookup problems. Good luck.
