I'm looking at a few possible speakers for my TORII. My Adagios are great but need a much larger room as they are very picky about distance from back wall and side walls.

I'm looking at Zu Essence, Tyler Acoustic PD15 for wideband plus tweeter configuration. Or Decware HDT, Omega 7XS or Super Alnico Monitors.

On paper, I'm worried that only the Zu Essence will go low enough for my taste vs my current Adagios. And will hopefully have a bit of that full range magic. But I haven't heard any of them. I listen to everything from jazz to electronic. But truth of timber is probably my biggest concern. Particularly with bass, I like a kick drum to sound like a drum. My Adagios do this extraordinarily well when in a larger room. But my old room was 18x21 and my new room is 13x16. Bass loads certain areas and there are nulls/cancellations in others. I have moved the room around several times and added bass traps and a couple panels. Everything sounds much more even, but far less relaxed than before, with some bloating in 40hz region. Very slight, but enough to make the speakers sound a little strained in my new room.

Any thoughts on the above mention speakers? Willing to try one even to be dissatisfied. I'm sure most of these will sound better than the Adagios in this particular case.

Using bass support would require both a preamplifier with dual stereo outputs and either multiple amps or active subs. But I'm afraid that would be too far removed from where I'm at with my system and budget. But open baffles with a passive crossover might work well. Just interested in trying the minimal or zero order crossover approach. I've only heard it a few times and was quite enthralled with the results. But never with demanding music or synthetic bass, deep organ or anything.

"Using bass support would require both a preamplifier with dual stereo outputs"

Not true, as maddog has suggested, speaker level inputs can be used and the bass can be adjusted to fit the room.

I have a setup very similar to Maddog's and run without a pre-amp.  Very good sound with the Torii.

So if I want to go full range with a sub or two, can I jumper the sub(S) directly off of the speaker taps on the speakers rather than the amp? This seems to be what Omega does on their Outlaw speakers that have built in subs. Just wondering if it effects the impedance or signal from the Torii to the speakers in anyway. I really don't want to feed the speakers through the plate amps line out. I'd much rather go direct from the amp. Nor would I really care to buy another set of $800 speaker cables to get the results I could from just using a decent cable to jumper to the subs.
