Recommend Speakers For Yamamoto

Zu Druids can be had for $2000 or less used on Audiogon but you have to respond quickly as they sell very fast. There are presently 4 pairs listed and they are all sold.
Zu uses your amp to demo these speakers at shows and Srajan of 6moons had Druids when he bought his Yamamoto. Should work fine, I would think.

I tried SET 45 amps like the Yami on my Lowther DX3, from 100 hz up, I really didnt work properly, I had to hook up a SS preamp that could probably move the lowthers by itself in order to get some sound out of it...
The JMLabs or B&W wont work.
If you are determined to use the amp, use it for mid horns such as the Altec VOT 806 tweeter, and biamp using some chipamp (gainclone) for the bass driver...
That should fit your budget, and probably not the size of your room.
You could also try a Fostex driver in some small cabinet and a subwoofer, try to get the most efficient Fostex driver you can find that would go low enough to cross over to an active subwoofer, say 100 hz maybe?
www.Madisound.com sells fostex and some cabinet kits also.

I am not sure if the Fostex will work though..I guess if you dont like symphonic orchestras you will do fine...
Get a very powerful preamp for that!!

I would try Tonian Labs TL-D1 speakers. They use a single 8' Fostex driver and ribbon super tweeter, having 8 Ohm impedance and 95 db sufficiency. supreme treble, life-like midgange, very good organ timbre and all these for only about 1500$. Indeed very impresive speaker; perhaps the best in this price range. Check it in www.tonianlabs.com.
Best regards.

Fertin 20EX-fullrange- Fieldcoil-32Ohm driver

in open-baffle(if you have the space)

could be a really easy load for your YamanotoA-08S

I forgot to mention:

The Fertin 20EX are 100db in(8-16 o 32Ohm).
