Jim,
I'm not sure about the current BE iteration of this speaker, but the previous version had just a single capacitor used as a high pass filter for the tweeter (I think this is still the case). The mid-woofer runs full range, connected directly to your amplifier, using no crossover.
All Reference 3A speakers that I have ever heard are very good. I enjoyed a pair of Reference 3A MM DeCapo i's in my system for many years. I've tried to buy a pair of the larger floorstanders a couple of times, but lost out via higher auction bids.
As a company, I highly recommend Reference 3A. However, I'm not a fan of the dull finish on the current DeCapo BE. Mine were finished in beautiful piano black gloss and they were very attractive IMHO.
