I have a set of Definitive Technology tower speakers, BP-10B, and a center speaker also from DEF.
All of these speaker seem to distort when played at moderate volume. I have never pushed them and they all do it on different amps. None of my other old Sansui's, Pioneers or my Bose speakers crap out.
I don't really want to spend the ridiculous amount of money they want for a new center speaker so I was looking to replace the speaker/crossover in the center speaker and see if this works. The towers and the center all have the same 6.5" woofers and same tweeters as well.
I have no idea of how to test the crossover to see if it is the problem. I have tested the speakers in the center with the 9 volt battery check and it seems to have 4 ohms resistance.
The woofers all seem to be in good shape.
What next?

If all of your speakers are doing it, even with different amps, possibly it's your source. What are you using for a source?

Assuming it is the speakers you might try checking for air leaks, it should be air tight. Unless you have a port, in which it's not. I'd still check to see if the port is loose or maybe something is blocking it. You could also try just bypassing the x-over if you think it may be the problem. But keep in mind, I would unhook the tweeter when doing this it will blow from the full range signal. As far as replacing the speakers goes, you might try parts-express.com or mcmelectronics. I would start out with MCM, they are cheap but pretty good quality. Sometimes a cheap speaker sounds better than a broke one. But really they are good, I have used their 6.5's and they sound nice. http://www.mcmelectronics.com/product/M ... 0-/55-2970

Hope this helps..

Thanks for the help. It seems it's either the crossover or the tweeter.
I cut out the crossover and tweeter in the center speaker and no more distortion.
Don't really need a tweeter as my Sansui SP5500X's have great tweeters and a horn for the highs.
I just needed more voice from the center to compensate for my old ears. Don't hear highs all that well anymore, lol.
