Default PMC MB2i SE - Bi-amp or Single amp

I have a pair of PMC MB2 SE on order.

I am trying to decide whether to use a single Bryston 28b3 on each speaker.
The 28b3 has dual binding posts, so one cable to the bass, and one cable
to the Mid/tweeters.

Or do a 7b3 on the bass and a 4B3 bridged on the midrange/tweeter.

I already have the 7b3's and 4b3 to do the bi-amp.

Has anyone tried bi-amping vs single.

Why don't you try the 7b3s first and hear if that's enough? Adding the 4b3 you will need an active crossover as well.

Well i am still waiting on the speakers, but good comments here.

I will try the 7b3's first.

And just for fun, i am going to run a splitter on my interconnects(no crossover) and try the 7b3's on the woofers and the 4b3's(in bridged mode) on the mids, with a jumper to the tweeters. Too bad i don't have a crossover to try.


BTW has anyone heard of any Board or electronic issues with the MB2 SE.

Just curious because i had a pair of Ib2i actives and had a number of issues
with the boards.

I also have a friend who has the Fact 12's and he had to send his speakers back for service due to electronic issues.

Just don't want that type of surprise again.

What taps off your amps will you be using when bi-amping?

Not sure if i understand your question.

The MB2's are 4 ohm. There is no selection on the bryston amps for 8 or 4 ohm.

Interesting their site does say 8 ohm. But the IB2 SE and BB5 SE are 4 ohm.
