If I ever went active I would want to crossover in the digital domain and use multiple DACs from something like Jriver (and add room correction as well). (variable for the sub and for tweeter units). I have 2 pairs of speaker wire to the two sets of amp terminals feeding Mids/highs, bass, supertweeter and sub high level, each with their own crossover. In fact I use my 300’s just the opposite of active. I’ve dreamed of someday bypassing the crossovers of my TAD CR-1’s but I would not want to settle for anything less than BHK’s and that’s not practical for me to add an extra pair of 250’s or quad of 300’s. The only thing I’ve ever had against active is that generally it’s done with quality amps, but not outstanding ones. Thats amazing that you’re actively bi amping with something of the quality of a BHK amp. PMC now make a BB6-XBD-A and, guess what, it uses their own crossovers and amps (but they still don’t offer the flexibility that I have with everything external and software crossover). I couldn’t get directly to the rear of the input terminals because of the transmission line cabinetry but by removing the bass driver I could get to the crossover board connectors and join the input and output leads together to bypass the three crossover elements. Pete Thomas knew exactly what I was planning to do with it (and said he favoured the analogue Bryston crossovers). I bought a pair of BB5s and a pair of the extra bass boxes. I couldn’t expect PMC to sell me just the speaker cabinetry but they made passive versions of the BB5 (they also made an equivalent box with just a bass driver in it, no crossover). The BB5-XBD-A was sold into studios (or pop stars) with Bryston analogue crossovers and Bryston power amps - I didn’t want the Bryston stuff because I wanted to choose my own crossovers, dacs and amps so that I’d have total flexibility in the choice of components (especially choice of dacs). When I bought mine about six years ago I based what I purchased on their BB5-XBD-A (the XBD stands for Extra Bass driver and the A for active). I went for PMC because I like transmission lines (I detest reflex).

Both these companies have always provided separate binding posts for their 3-way speakers so that tri-amping is possible. studios that aren’t using Genelecs), they are ATC and PMC.

Here in the UK there are two main companies that sell to studios (e.g.
