Well, I've been doing a lot of listening to my new dual Captivator/Triple 12HT setup. It's music only and I have the Caps HPFed at 20Hz and crossed over at 100Hz.
I'm running my iPod and CD player through an Alesis MultiMix USB to a Behringer DCX-2496. From there, I have 2 ouputs to a Crown XLS5000 running the T12s in stereo and 2 other outputs to 2 other XLS5000s running the Caps in 8-ohm bridged. Dedicated circuits for the amps, each one run with 10AWG.
I absolutely love the sound of this setup. It's soooo much better than the Klipsch RF-83s they replaced (louder AND sounds better at all levels). However, I think I may have developed Carp's disease of not enough bass......
For everyday whole-house listening it's great. Perfect, as it may seem. But when I really
push it, the clip lights on the XLSes for the Caps start lighting up before I get to the level I want. The gain on them is maxed out, and the gain on the amp for the T12s is just above halfway, which gives me a good system balance at "normal" levels.
Here's what I'm looking for.....If I turn it up until I get the clip lights for the Caps and then max the gain to the T12s, I get the volume I'm after. The only problem is the amps for the Caps are already maxed out and the T12s run off and leave them.
So I have one of 2 problems. Either the Caps are sucking so much power that I'm getting a line voltage drop that limits the output and causes the clip lights (the lights in the house don't go steadily dim, but they do pulse pretty good with the bass) OR the 91dB sensitivity is just plain outmatched by the T12s.
I'm thinking it's the latter. I've been looking at other options and think I would prefer to stay with JTR. Looks like my choices would be the Orbit Shifter or Orbit Shifter PRO. I'm really liking the PRO version because of its 103dB sensitivity and passive operation.
What thinks the masses???? (about my dilemma, not sanity)

EDIT 2: To alleviate some confusion, these are set up in my music room, which is supposed to be a 10x12 dining room. It's open to the rest of the house and fills about 8k cuft. Not a big open space with high ceilings, just several rooms with 8' ceilings. My "listening position" is dynamic, meaning I am using it to fill the house when I'm moving about. I am NOT listening at insane levels, right by the speakers.
