Any experience with a crown K1 or K2 amp?

Hi there, I am looking into the crown K2 and K1 amps for a subwoofer project. I could use any user info and am curious to see if it is still musical or just all out control like no other? I really love the idea of a 3000 damping factor and am curious to see how it plays out, Thanks

Hi, I use a K2 with great results. Very fast and articulate bass. I use the K2 to drive a pair of 7 foot basshorn speakers using twin 18" drivers each. The K2 mates very well with them. The basshorns are crossed over at 100hz down to 30 hz.
I've been using the K2 for a number of years to drive my two 18" Infinite Baffle Subs. The K's are very rare in the pro world as they don't use fans for cooling. Either K is a great choice as a sub amp.
They like to be fed a higher gain pro balanced signal vs. consumer unbalanced. I had problems with the amp going into "sleep" mode with the weaker unbalanced signal, but Crown has a fix for that. If you go the K route and have to use unbalanced, PM me and I can email you the "fix".
