Need list of 92db speakers and above.

Okay...I see I may of left out some critical additional requirements. :-)
DIY may be an option.
Prefer no cross-over with single driver.
Cost under $3000.00 used.
Full range as in range similar to the Cain & Cain Abbys.
Floor/shelf does not mater....just sound.

Check out Bob Brines speakers, as well as those listed by Decware.

Yowsa, Dean - you are really jumping into this SET/single thing with both feet!

To try a totally different single-driver experience from the Abbys, I'd suggest the Hammer Dynamics Super-12 kit. It features a customized 12" fullrange singe driver with a supertweeter crossed in above 12kHz. 97dB@1watt and 45-21kHz freq response. Upgrade the stock tweeter with an affordable Fostex FT-17H tweeter and top end extends to 50kHz.Kit is only $650 and comes with everything you need except the 2 4'x8' pieces of wood needed to build the cabinets.

The former Single Driver Website has a DIY/mod section devoted to thsi speaker with lots of tweaks and upgrades. You can also post/search the new FullRange Driver website/forum for even more info and advice from others.

Audio Note Speakers also come to mind as both kits and pre-assembled. Aprox. 94dB and designed specifically for SET amps. These designs are intended to be placed in or near corners for loading and best bass response.

For something totally different, but just as impressive look into the Bastanis Prometheaus open baffle speakers/kits. The finished speaker is out of your price range, but the kit makes it. Here's a few reviews of it: 6Moons, Enjoy The Music, Dagogo .
