Need list of 92db speakers and above.

You may want to look into the Tyler Acoustics Pro Dynamics line. These are not single driver, but the Eminence drivers used in them are super-high efficiency (about 101-102dbs). The mid-line PD-20s reach about 42hz on the low end (20K on top) and go for about $2800 new. You might be able to buy their larger bretheren used to get lower bass extension if needed, but the line is still relativel new so there are not many (or possibly any) available used.

I also recommend the Audio Notes already mentioned. Very good bass extension, especially if you are placing them at or near a corner...

I'll second the Zu Druids although technically they are a 2-way.

Checkout the Lowther America site too. They also have a budget line of drivers that look pretty cool:

Boston Acoustics VR3 I believe is 93dB. You might want to check out the Welborne site for his list of efficient speakers that can be driven by SET amps: http://www.welbornelabs.com/recomendspeaks.htm

no offense, but with a 'night light' for an amp, go with something like a klipsch heresy. at least they can fake real power. if you like rock music however, don't build a system around an set amp. in fact, don't build a system around any amp.
