Default PMC MB2i SE - Bi-amp or Single amp

That is an interesting article, but they talk about the fact speaker crossover.

I assume(hope) the same care is taken for the MB2SE speakers also.



I had a pair of IB2i Actives and had to replace the boards 3 times.


Oh great, sounds like you are ready to go.



BTW - What color did you go for?

Just wanted to chime in. In my opinion, you should start by looking at what SPL levels you want to listen on, and then go for specific distortion levels. A single amplifier could well be good enough for your use. However, some people complain that the MB2 is bass-lean, which if you find is the case you could help by using a different sensitivity amplifier on the bass transducer; alternatively, you could use a +3 or +6 dB pad on the input to the bass power amp.

Also wanted to add: Either case, you have two options on how to split the signal - either use a passive crossover (i believe your MB2 comes with one, mine comes without), or an active crossover like the PMC 10B (for tri-amping) or Bryston 10B or 10B-sub (for bi-amping) and then bypass the passive crossover built into your speakers. The active crossover solution creates less IMD between the channels during amplification. This is because with an active XO, the LF amp only amplifies the LF, and the MF/HF amp only amplifies that, so there's less non-linearity. With a passive XO, the MF/HF amp also gets and amplifies the LF, and includes the distortion products of LF in its output shifted up to the MF/HF area; then the LF is cut out by the passive XO, but the distortion products remain.
