I am trying to see what type of speakers I can get away with (efficiency wise). How loud do you play your music?

Thanks!
My speakers a Lowther PM7A drivers in homemade folded TQWT cabinets. They are 15 ohm and 100 dB efficient. The V4 plays plenty loud.
I am only guessing, but a 90 dB, 8 ohm speaker should be fine. Especially if the bias is set at 2 amps. Mine is set at 1.25 amps, but that is plenty for this application.

I play my zen amp(1,3A bias) with some kind of coxial like lowther. but sensivity is 86-87db. I dont know what wattage is now from my zen, but sound prwesure level in 15m3 room is about 110db. seiuos..

but I am planing to built, sensitive speakers around 92-95db/w/m 8 ohm. it shpuld work much more better.

also zen v4 has no bass, without good preamp. trying to conect to variable output or passive potnciometer is bad idea..
 
My ZenV4 is setting at 2A..... I use a two way home made speaker.. the woofer is a 6,5" vifa and the tweeter is a Vifa speakes also ! I don't know the sensivity of the speakers ! The crossover is a 6db/octave....
so... the Zen V4 have a lot of difficulty to reproduce the bass, the bass have no impact and the medium also... people say that vifa speakers are hopeless to ZEN damping capability.....
so....
 
I have a ZenV2 running at about 2.4A bias with a 34Volt rail, which I use to drive a pair of vintage alnico Isophons in a 12ft folded voight pipe. Great sound and plenty of bass. I would guess the sensativity to be about 95db. I wouldnt try anything much below 90db. I would agree that a good pre-amp is essential (the Bride of Zen is cheap and excellent).
