PMC and what electronics ??

Hi Brizon
Did you use a single female to 3 male balanced cable?

I recently purchased a pair of the tiny DB1+s. Amazing sound from such a small speaker. Mine are passively bi-amped with a pair of PS Audio Trio A-100 amps. Very nice sound once I got the sub integrated properly. The nice thing about the A-100s and bi-amping is, they have a rear panel switch which allows for bi-amping with a single cable.

He is contemplating of getting another two units of 4B-SST since the speakers can be tri-amped.

That would be overkill. The Vifa midrange on the EB1i has a very small magnet (240 grams) with low Xmax and FOR SURE the tweeter does not need 200 watts...

I'd suggest your friend looks for much smaller powered amps for the tweeter and midrange - a much lower powered class A might be the ticket.

FWIW: It is definitely worth triamping as you can remove IMD distortion (distortion bleeds from one bandwidth to the next when you use a passive crossover and a single amplifier that is trying to send several AMPS to the Woofer but barely a milli-amp to the tweeter)

Thanks for the thoughts Shadorne. That would make sense.

No I did it single ended as I couldnt find balanced splitters.
