Don't forget that if you choose a tube amp with a lot of output tubes or one that is biased in Class A, it will likely heat up a small room. If you can easily control the temperature in the room, there would be no issue.
Tube Monoblocks for heavy music on Khorns
What tube monoblocks would drive Khorns the best for big bass/heavy metal music? I obviously can't go the SET route for the BEST sound. I was thinking about some BIG monoblocks to help the Khorns 15" driver REALLY move. My room is small. I could even experiment with adding a large sub like a Velodyne HGS18 in the future, too. However, price is an issue. Another interesting Idea, what horn speakers can really compete with Khorn for around the same money for reproduction of bass, Etc??
