Tube Monoblocks for heavy music on Khorns

Atmasphere, I have the ability to change the phase, frequency, slope, delay, HP, LP, band-pass, gain levels of all circuits with my Minimac. Also, while incorporating these crossovers I can take microphone measurements to see how the driver rolls off naturally as well as take in-room measurement of each driver on it's own. I also have a 31 band EQ to EQ the entire system or what not to get a flat in-room response, if even just for a reference point and go from there. All from the listening position! This is all done in one digital to analog conversion from one source. I do understand what you are saying about the passives and can see your point. In the end, what sounds right is right and you never know until then. But there is a lot going on here in this particular active system that could be advantageous.

Good point Tjnif. Sometimes I do not enjoy constant tweaking and would rather just hear music. I will check out the site. Thx

Atmasphere: I thought the passive high level crossover was one of the bigggest problems for tube amps. Wouldn't an active system alleviate THAT particular problem. I am sure it would create other problems, too??

Right.

I've spent a lot of time in the recording studio. I think you will find that the more you process the signal digitally, the less musical the final result will be.

An fact the more you process the signal, analog or digital, the less musical the result.

IOW, that is why most passive crossovers work better than active ones, unless the speaker designer designed the speaker for a particular active crossover.

K-Horns are so efficient, that you really don't need hardly any power at all. Heck, your iPod you could prob sufficiently drive them.

Obviously, being horns, you definitely want a tube amp - and there are many very good choices amongst low-powered tube amps currently available.

I love the A-S S30 - I own one - but, that amp really shines best with 16 ohm speakers or higher and I believe the K-Horns are only 8 ohms. (Using Hedlund Horns with AER mk 1 16 ohm drivers, I was nearly chased out of a large room by an A-S S30 during a suddenly loud passage).

Since you want a lot of head-banging capability and heavy driver control, I would look at any of the moderately powered amps from VTL, BAT, Audio Research, and Quicksilver.
