F112s back on line

[PHC1]

Well, I finally got a chance to put my 2 F112s back into the system today and tweak them out with the Sophia 2. The SF speakers I had and Sophia are very different in bass response so I had to start from scratch with dialing in the F112s. This time around it was a much easier and more efficient setup now that I have a system worked out and the Bryston X/O was not involved. Starting out with each individual sub re-dialed in for phase to each speaker, the crossover worked out to be around 38Hz to fill out the bottom end of the Sophia in my room and using the SPL meter and gain, ELF and crossover slopes, I was once again able to dial them in to 20Hz within +/- 1dB.

Wow, I almost forgot just what these subs add to the system. The bottom end is now much fuller, the instruments are once again "fleshed out" with greater palpability and 3 dimensionality. The bottom octave now "tickles" my feet as it energizes the room and the floor, kick drums have more "flesh" and greater impact to them while being warmer, fuller and rounder sounding.

Since the crossover is not a brickwall type of a filter and I usually use the gentler slopes, the subs augment the Sophia not just at 38Hz but "creep up" gently up higher and fill out the whole bottom end of the Sophia just enough to add some overall warmth and fullness down low which shifts the tonal balance ever so slightly to a warmer, fuller presentation. Takes a bit of fiddling to get it right but once done, most enjoyable. I love these subs!

The Bryston crossover is not necessary with this system as the Sophia 2 needs only a bit of augmenting and I don't have a reason to take bass off them since they are already so linear down low.
