Def Tech Replacement Drivers

[chicago25624]

I've got a pair of Def Tech BP20's collecting dust and began wondering here at work, Oh so very busy am I, anyway back to the point.

I began to think about replacing the drivers with, say, Focal, Seas, Aurum Cantus, to name a few raw drivers. Anyone had any luck, or tried this before?

Thanks.

The drivers and crossover in any speaker system are designed to work together. Replacing one without also replacing the other is unlikely to give good results, unless the replacement drivers have performance characteristics virtually identical to the originals.

Additonally, I would replace all of the drivers with those that are closely matched to what is there.

And if sounded bad, I would put the originals back and just build a set.

Just spit ballin' here.

A lot of drivers Def Tech use are Seas or Vifa drivers set in baskets cast with the definitive logo. Sure better drivers are made, but the ones they used are quality to begin with. I don't know about all their newest speakers, but this was the case with a lot of their BP series in the 90's, and the drivers don't appear much different in the DefTechs I have bought in the last few years. Email Chet at definitive and ask him specifics if you want more details about what drivers you have exactly in your speakers (or pull them and check them out like I did!).

Yeah, my Def Tech BP8bs and BP10bs sound like excellent speakers to me. I love them for HT. The only reasons they are not my favorites for music are a preference for monopoles in that application and a midbass hump. Quality wise, I think they would be hard to improve.
