Does anybody know the T/S Parameters for the drivers found in the DefTech BP-2X? Thanks.

[ThomasW]

That info is probably proprietaty, and mfgrs don't usually give it out when they're using custom designed drivers.

[JasonWUC]

Sorry, I didn't know that the DefTech Drivers were proprietary.
So, there's no hope of resurrecting an old BP-2x except for the very tedious task of trial and error?

[ThomasW]

You didn't ask about resurrecting them you just ask about the T/S parameters.

Your options are buy replacement drivers from the mfgr. Buy a used pair and take the needed parts from them. Gut the boxes and rebuild from scratch using DIY drivers

[JasonWUC]

I guess resurrected is not the best word. I want to gut an old BP-2X and use the drivers to make some DIY speakers.

[ThomasW]

Why bother? They're tired, old mid-fi drivers, and free info isn't available for them.

You could have a design service measure the parameters, but that would cost more than they're worth.

Start fresh with new drivers and a proven DIY design

Def Tech uses Vifa drivers,at least they used to.
