Re: Subwoofer for sierra-2
I have two F12's and really love them, would highly recommend a pair. Remember that if you order two at once you get a 10% discount as well, helps a bit. Mine are in a 14'x11' room and I run them at half volume on their dials and -3.0 dB on my processor and they are capable of gut busting, room shaking bass, FWIW. They are insanely clear as well, no boominess at all and I don't even have room treatments yet. I've never heard the L series subwoofers, though, so I can't really comment on how they stack up. The main difference is the drivers and I feel a lot more confident in my aluminum drivers than I would in paper cones for theater duty, but since you're listening at lower volumes I doubt it would matter, so the L series would probably be fine.
Do not get two different subwoofers, whatever you get, make them an identical pair, there are even worse headaches than crossovers, they just will not blend correctly. The only way I've seen people make it work is with pairs of different subs, and using one set as a midbass module.
