Can You Get 1,000 WPC Out Of Regular Wall Socket?

.
I own the notoriously inefficient Infinity Kappa 9 speakers. They are known for bringing amplifiers to their knees. They need to be biamped to be their best. It takes a lot of power to wake them up. I'm thinking of throwing one or two pairs of the D-Sonic 1500 wpc monoblocs at them.

Mitch,

I for one would be interested to hear how they fare compared to your big Pass amps with those speakers.

Have you ever tried any other Class D amps with those?

thanks.

Can the D-Sonic put out 1500 wpc 24/7 or just for milliseconds?

Mitch, there isn't much information provided about those amplifiers at the D-Sonic site. If you haven't already done so, I would suggest that you research and/or try to confirm with the manufacturer that they can handle the extremely low impedance of the Kappa 9.

The Kappa 9s, when used with their "extended/normal" switch in the "extended" position (which iirc seemed to be the most commonly preferred setting), go down below 0.8 ohms at multiple bass frequencies, where lots of energy is typically required. The "normal" mode is not quite as severe, but is still very challenging.

Also, I don't know what their phase angle behavior is in the bass region, but it wouldn't surprise me if it was significantly capacitive, adding to the severity of the load.

My impression is that the impedance characteristics of the Kappa 9s, rather than their inefficiency, are the main reason for their reputation as amp killers, although both factors undoubtedly contribute.

Map, I've never tried a class D amp before. The whole
concept of small amps delivering that kind of power is
intriguing to me. I have Carver Silver 9t monoblocs that do
an excellent job in a biamp config on the Kappa 9. They
weigh only 13 pounds each...the Pass monoblocs weight more
than 130 lbs each. The Carvers actually deliver bass with
much more authority than the Pass monoblocs. But, the
Carver amps are 20-25 years old. I need to get rid of them
before they go bad. I'm looking for some 21st century
amplification and to save some money. If this class D stuff
is all it's cracked up to be, there's nothing more than I'd
like better to do than get rid of all this "Big
Iron" and go small and efficient.

Ddd1...Hmm, no mention on the D-Sonic site on whether the
1500 wpc is sustained or for milliseconds. That really
changes the picture if it's only for milliseconds.

Al...I will make inquiries directly to D-Sonic and do some
research as you have suggested. D-Sonic has a 21-day trial
with a 10% restocking fee.
