Speaker for your low power tube amp?

[EmergencyDpt]

I'm making a frugal horn (www.frugal-horn.com) to go with my amp. These speakers use a single driver and rely on expertly designed wave guides to reinforce the sound. You can have a very low power source and still have a decent sounding speaker. Best of all it's a diy.
I'm putting together a group buy for wood cone speakers. Of course they have some draw backs because the increased mass of the cone. However they look fantastic.
Each 6.5 inch, 8 ohm speaker driver will cost you $40 plus delivery to your house. I need a minimum order of 50 but I'm willing to buy the last 10 on credit and sell them later if I can get 40 paid for in advance.

I am posting this in this forum because lower power tube amps benifit from an efficient speaker.
If you have any questions, you are welcome to ask. These retail for $79.99.
