My first thought is to try just the one E15HP crossed over at 50-60Hz. The space is pretty large. Basically a large open room with vaulted ceiling.
Other ideas include buying another E15HP or should I look at 2xF12? This system is solely for music. Pretty much all music types including some Classical, Jazz, classic rock, 80's rock, new rock, Blues guitar, Jazz vocals, Singer song writer, etc...
1) Use the one E15HP
2) Get a second E15HP
3) Buy two other subs? F12, other...Rythmik office is literally two blocks from my office.
Since you already own the E15HP, I would start there. Integrate it into the Phil3 system and see if you and your wife are happy. If you are, then you're either done or you can buy a new sub for the bedroom.
If you're not satisfied with the E15HP paired with the Phil3, buy a second one! Rythmik lists the E15HP as +4db over the F12 so even going to two F12s likely won't help. As you said, I would try crossing the sub at 50Hz, possibly even lower (that's what I'm doing with my subs paired with BMRs for a mixed music / HT system).
You probably know this, but just in case: Integrating subs is fairly difficult. You need to find the right placement (sub crawl), find the best crossover, align the phase, and then set a gain that blends well while also giving you the "thump" you're looking for. Most AVRs will help with the integration, but relatively few stereo processors do. You also typically need one of the better room correction variants (e.g. Audyssey XT32) to handle a sub like the Rythmiks that go down to 14Hz.
I'm a big fan of multiple subs, which can sound much better across the whole listening space, but they're also much more difficult to integrate. Relatively few AVRs will independently integrate two subs. My approach has been to let the AVR handle the first one, and then I manually integrate the second one using a UMIK-1
. Despite the hassle, I do think it's worth it. My BMRs sound wonderful, but my room is an acoustical mess, and the subs + BMR initially sounded awful together. It was exactly what audiophiles complains about
: you could hear when the sub kicked in, it overpowered the mains, and the effect significantly detracted from the music. After calibration (which took a couple hours), the whole system sounds like an integrated whole and I'm very happy with the result for both music and HT.
One final thought since you already started down a path of blasphemy... You may have a case where running the mains full-range with the subs makes sense. That will make integration even harder, but you can think of it as a Geddes-style
system since the Phil3 woofer is already so capable.
