Something Different

Never heard of these before--or the manufacturer "Klein and Hummel"--interesting design incorporating Altec drivers and crossovers. Pricey but if I had money to burn they'd be a cool/unique addition to my collection......

I'm wondering if these would be prone to microphonics--having the amp and speakers in the same cab--could that be a problem at high listening levels?

That's German perfection, what I have heard is, these amps are extremely good sounding!

Looks like he's just pulled the listing after receiving only one offer? I see they're re-listed at $1.00 with no reserve....

Not a concern in a well braced and damped enclosure. Also, considering the system as a whole, high listening levels aren't going to happen. These are what i'd call "medium" sensitivity loudspeakers, driven by medium power(20-30 watts?) tube amplification. They're going to run out of gas before it gets very loud.

But, i'd love to spend some quality time with them in a familiar room. I am intrigued by the 411 woofer in that fairly "loose" appearing bass reflex alignment.
