Wow, Zu Audio has some funky products and the new Soul and Soul Superfly are perfect examples:

http://www.zuaudio.com/loudspeakers/soul.html

Efficiency: 101 dB 1W/1m
Impedance: 16 Ohm nominal

Prices for Soul and Soul Superfly are $1800 and $2600 (Global Direct Prices)... Daaaaummm... Not sure why I'd need a 101db speaker with my 300watt amp, but the Soul looks funky and since the price includes shipping, it certainly makes it tempting... I can't wait to read some reviews...

Oh and RGA (if you find your way into this thread) you need to review a pair!!!

Can a speaker be easier to drive than 101 db @ 16 ohms??? I should be able to drive it with a headphone amp
