I purchased 801 series II that have been upgraded to series III. I am driving these with a Hafler Dh-500. I was in heaven for about two months and I now have a distortion on the left channel. in the woofer and is extreme. does this mean the driver or cone needs to be replaced? any input here is welcome.

Only a dealer can tell you what is wrong but it doesn't sound good (sorry for the pun!)Cyrus CD8x --> Cyrus AVMaster 8.0 --> Cyrus Smart Power Plus --> B&W 602S3 / B&W LCR600 / Eltax bipoles -
HI jca,
You need to isolate the the problem to the speakers or the electronics assuming you are hearing the problem in only one channel. Reverse, left for right, the speaker leads at the amplifier. If the problem moves to the other speaker the problem is with the amp. If the problem stays in the same speaker the problem is the speaker.
Betcha the problem is the electronics, probably the power amp. B&W speakers are tough.
Of course, we have no idea how you use the system. Some people really abuse their speakers.

I agree with Karma.
You need to isolate the problem to that speaker. Switch speaker leads on the amplifier and even the sends from the Pre-Amp to make sure it is the speaker.
If it still makes the noise, call your dealership or the closest dealership and they should be able to help you. If you really need to know the part number of the driver, B&W labels the back of their drivers. So you might have to break out the screw driver and some patience...-JoeComment

time for some tools
I did change the wiring and it stayed with the speaker. looking at the front of the 801, it looks pretty straight forward to take out the screws and pull the driver. am I over simplifying? i have a tendency to do that.Comment

If it is from the Bass Driver than I don't think you are over simplifying it.
The midrange is a different story...-JoeComment

Could even be a problem with the crossover.. i would take it to the dealer and see what they say.. I had a faint noise coming from one of the woofers on a XT4. Dealer replaced the complete speaker without even taking the one i brought in out of the box.Comment

cool, I will tear it up and let you know how I make out. I there a check I can perform on the driver itself. I say a picture on audiogon of a driver for sale. the picture had an Ohm meter hooked to both leads. If I remember correctly it read 5.6 ohms I guess. could not make out if it was reading impedance or resistance, or are they the same?Comment

aquaanox,
I guess I could, but these things weigh a ton and are in my basement. If I can take the driver out and check it or have it checked, it would make life a whole lot easier.Comment

Move it around and see if anything rubs.Originally posted by jca31
Look for damage on the Voice Coil, Spider, or anything else.
To be honest DCR really won't tell you too much...-JoeComment

thanks, i did move the woofer and it does not feel or sound as if it is rubbing on anything. What would I be looking for in the way of damage from the back side of the driver?Comment

Tears in the spider, places where glue isn't sticking any more. Loose tinsel leads.-JoeComment
