Best speaker for medium to low power tube amps??

2nd of the Virgo's. Either version. The new ones are better, the old ones are a steal used! BAT VK60 makes a nice match.

I got mine from someone who had been driving them with a 50 wpc tube amp in a room about 12 x 15. He had been very happy with that combination. ( Sold because of low WAF for multiple systems. ) Other sources have also been happy with the Shearwaters ( 88-89 dB/W sensitivity ) combined with tube amps in that power range.

I myself am using a ss Celeste W-4070se ( about 70 wpc ) with my Shearwaters There is gobs of power for my 15 by 22 room.

Another possibility might be Reference 3a. The DeCapos are rated at 92 dB/W. I heard them do very well with Antique Sound Lab 10w tube monoblocs at the 2001 Montreal show.

You might want to consider Revel Performa F30s; I am running them in a 12.5x19.5x8 room with a Jolida SJ502a which puts out ~60Watts/ch (I am using Ei KT90 power tubes; I'm not sure if that increases the power at all, but the amp is rated to deliver 60/ch).

I wanted a speaker that did deep bass as well as a really nice midrange and good detail/air etc. Having auditioned several in the 3-5k price range I settled on the Revels and am very happy I did. I was a little concerned that the amp would not be able to drive them well, but it has no trouble at all (I rarely take the volume past 25%; beyond this the SPLs become quite uncomfortable, though not at all distorted- I just can't listen that loud for any length of time :).

As always, audition before you buy :).

i like the jm lab electa series. the older ones are cheap now and sound awsome. the sonus you mentioned are great speakers as well.

I think the new Von Schweikert db 99 sets a new standard in efficient speakers, at $5995 or $6995. They were one of the best-of-show at CES, with the benefit of the $50K Wavac amp. The speakers have active amps for woofer 'boost', so require AC plug in. My other favorite is the Roman Audio speakers, floorstander or monitor, with the diaural crossover. We're finally hearing what the diaural circuit really can do with both space and music! Again, fantastically good speakers at reasonable prices.
