Let me start by saying "I know nothing about Tube friendly loudspeakers". Actually the only thing I recall specifically is that you want a relatively low impedance to the amp from the driver. Anyway, I was running the 18" Kappa in a 300 L box to see if it would be suitable as a sub, while it didn't hit the 20's it did hit the low thirtys with decent efficiency, with 4 watts they hit 101 db which in my experience is lots for home use (I rarely go over 95 db, except at party time.....heheheheh) but what caught my eye was the low impedence thru most of the frequency range with a max of 30 ohms at around 40 hertz, (below resonance it peaked at 85 ohms). I'd like to hear from the experts to see if any of my conclusions are correct.
