Need advice...and plans [message #35905]

I am reading that the thermionic series is better for tube amps, but I see alot of people using 300B SE amps to drive Theater 4s.

I have a pair of home made 300B amps and want a matching pair of home made speakers. I have room for either the Theater 4 or the Thermionic 3. So which would be better for my purposes?

Others seem to have no problems driving the Theater 4s with 8 watts of 300B power - would this be a good route to go? If so could I have plans for the Theater 4s? (or the Thermionic 3s? or both?)

On a side note - The Pi speakers seem to be defying the "rule" in speaker design that a huge driver cant reproduce midranges correctly, and sound ponderous and slow. However I hear nobody complaining about this problem, and hear only superlatives about midrange and speed. So how do the Pis pull off using a 15" woofer and a Horn and still sound fast while the B&W N801 with its huge 15" woofer is the slowest sounding speaker I have ever heard - even with a half kilowatt amp driving it?

thanks for any help!

My Theater 4's are driven quite well by my Paramour 3.5W 2A3 amps. And the sound is anything but plodding! Listening to "Duke Ellington at Newport" the other day was a hugely dynamic and properly paced experience! -Almost as if you were there...!

Either the Theater Series four π or the Thermionic three π speakers would be excellent choices. Theater four π speakers sound better to me in corners or up against a wall, and Thermionics sound better when pulled away from the walls a little bit. You'll have no problem driving either model with 8 watts.
