Speakers for my Golden tube SE 300B II SE 9w Please help

Some of the best speakers I've heard for low output SET amps are Hartley Towers. They are 96db efficient and very inexpensive, if you can find them.

If you are the DIY type or know a good cabinet maker, I strongly suggest that you check out the Hammer Dynamics Super12's kit($650). They feature a full-range driver, super tweeter, crossover parts, and are 97dB efficient. The Super12's deliver gloriously detailed, coherent, sound with deep, realistic, bass. The speaker enclosure is fairly simple to build if you have any woodworking skills and tools. Or, it should be pretty cheap to have made by a pro.

In fact, many people have stated that the Super12's were one of the surprising highlights of last month's 2001 Vacuum State of the Art Conference (VSAC-2001) in Silverdale, Washington.

Here's the link to Dick Olsher's review on EnjoytheMusic.com(the super-tweeter has been upgraded since the review):

Do a search on both of these forums for "Super12" or "Hammer Dynamics" to read owner opinions:

If you are into horns, I would recommend the oris horn 150 available from welborne labs or any well designed lowther horn including the voight pipe which is real easy to build. The Oris's are the best speakers I've ever heard. If you don't like horns, you can also look into the triangles which got real good reviews in stereophile. The only one I've heard are the tituses and they are awesome for 500 monitors and they were being pushed by custom 2a3's that put out a whopping 3 watts. However, if thats an indication, the other triangles should be better.

Silverline's are a great rec. They're very efficient and tube-friendly. Impedance doesn't dip below 7 ohms. They have incredible mid-range and well-built time-aligned cabinets. Driver quality is excellent.

I use the klipschorn with these amps and they work fine.
But for woofer I use a CJ Mv50 (fantastic).
