Slam possible with Tubes instead of SS ??

Larger or multiple drivers optimally driven by the right matching amp is always the key to "slam".

Larger rooms will require more, so room size and acoustics to some extent ( I call this the "listening environment") is another key factor.

Best bass slam I ever heard was the GR Audio open baffle 12" high eff co-ax w dual powered on-bard subs (ss on the subs, 18 wpc tube amp on the co-ax) @ RMAF 2009. So the answer is....maybe??????

The official sensitivity rating for the Snell C/V is 90db @ 1 meter with 2.83vrms. Nominal impedance 8 ohms, minimum 5 ohms.

Blueskies, I'm using both a tube VAC PA 35.35, EL 34 amp, and a Plinius SA 100 MKIII. Both provide good slam with my speakers, 12" custom Tannoys, but the Plinius has it all, smooth, very powerful (the dynamics will scare hell out of you), great imaging and soundstage. I bought both amps here on A'gon for $2400. You can get one or the other, or both! I do think you would be happy with th Plinius, though. My 2cents worth.

Dan

Actual test measurements like those done by John Atkinson of Stereophile often provide a more realistic presentation of the actual specs of the speakers.

If you look at the link in my first post, you'll see the test figures differ by a fair amount from the official factory published specs...enough to make a difference when mating them with a tube amp.

IMO.
