Speakers for a 15w 6v6 integrated amp?

You may want to check out recent Forum threads that have been very positive for the Tekton Design Lore when matched with tube amps. 30Hz-30kHz frequency response,8 Ohms,
high efficiency (98dB), linear speakers. They retail for around $1000 - 1100, direct order from tektondesign.com.

Also featured in several very good virtual systems on Agon.

Tannoy may want more power and different tube,,,I would lok at single driver full range, no crossover designs.

Omega Super Six Alnico Monitors with Deep Hemp Sub
Omega Super Six Alnico XRS
Both of these will shine with 15w of power if you want to buy used look Omega Super 8 Alnico XRS.
Contact Louis at Omega, he is a great guy and will set you up right.

Given your musical taste, I`d give strong thought to the Omega,Tekton or Zu speaker lineup.

The Coincident Technology Triumph Extreme's are amazingly good monitors that are very easy to drive. If you couple them with (put them on top of) the passive woofers that Coincident provides you get an excellent fullrange speaker that is at ideal listening height.

The Devore 3XL is also an easy to drive and very good speaker.

Fritz speakers make some excellent monitors and some full rangers that are very good. They sell direct so you get great bang for the buck, plus "Fritz" is great to talk to and could provide you with excellent advice.
