B&W 801D trouble

Hello

I managed to blow up both tweeters on my 801D speakers and have a set on order which is on back order arriving next month. Now when I play music the sound on the midrange on both speakers are extremly distorted and muffled. When I crank up the volume pass the half way point the sound gets clear on midrange speakers but gets distorted again after 10-15 seconds.  When I use the headphone on the pre amp the sound is crisp clear.

Since the crossover for HF/MF for 801D is on the same circuit on the  will the midrange sound be effected this bad? How could I tell if perhaps the crossovers on both speakers are damaged? any other troubleshooting guide is appreciated.

BTW, I have eliminated the Audio equipment as with the headphone the sound is perfect so it is the speakers.

Thanks for your reply

I don't think it is the crossover. You may have damaged the midranges along with the tweeters! What amp were you using? B&W's are pretty robust so you must have been really cranking them!

Sorry for your troubles, pry a case of amp clippage frying mids and tweeters.

Halfway volume is usually the max for most stereos.

  Tweeters usually go zapped by under powering. Mids also.

 Would have a look at the crossovers for fried caps, and look at the mid ranges also.

 Been there, feel your pain.

Thanks guys!!!

I am using two  T+A  A1530 Amps with output of 500W at 8 ohms in mono mode using Transparent speaker wires. I was cranking up the volume pretty loud LOL and I shall pay the price now.

I ordered two midrange and swapped them and did not see any difference. Service technician thinks it is the crossover and says most likely the sound coil (I think that's what he said). I have two HF/MF crossover on order along with the diamond tweeter domes for both speakers. Service person says it will take them 2-3 hours to change the dome. Last time the tweeter dome was changed it was just plugs and play so not sure if I am missing a step.

Is there soldering involved in swapping the crossovers? I have soldering iron and know a little about soldering. Would have been nice to have the instructions on how to swap the crossovers.

I am thinking change the crossovers and then replace the tweeters before powering them up. Any suggestions is appreciated. Thanks again guys
