Best Efficient versatile Speaker reaching 30Hz?


When it comes to speakers, I believe efficiency is key. However, there are two drawbacks on efficiency:

- lack of low frequency --> They hardly ever reach below 30Hz
- lack of versatility --> They tend to play better accoustic and classical music than rock, for example

My question: What is in your opinion the best efficient speaker (I guess 93db into 6-8 Ohms is efficient enough) that reaches below 30 Hz and can play all types of music?

Audio Note speakers will do that.
The An-E is 95db effiend and goes from 18hz-23khz at ± 3db. Although they
say on thier website -6db which is just another way of saying it.

There is a Von Scheikert (sp?) model called the DB93? (I am really butchering this name here) that is very efficient and goes pretty low. It has a built in powered woofer section............ Any it looks very interesting. Maybe someone else can chime in on this with a bit more (accurate) info.

The Wilson Alexandria.

Nominal Impedance: 8 ohms
Woofer: One 15 inch - One 13 inch
Midrange: Two 7 inch (vented enclosures)
Tweeter: Ambience: One 3/4 inch Supertweeter
Tweeter: One Inverted Titanium Dome

95 Db @ 1 watt. Down to 18 Hz. Good luck with coming up with the coin for a pair. Pretty amazing that they are that efficent with the drivers they have.
