Help power pair of Infinity Kappa 9's please

I do not have them, but if anyone can get proper driver specs a impedance compensation circuit could be added. I worked at SpeakerCraft/Marcof Electronics in the early 80's we used this circuitry then, we had great computer programs, but it was still a guessing game. Today, we can model exactly how a speaker will behave. Unfortunately, I doubt the information is available on the infinity's. As far as Phase data, You'd have to have the original crossover design and crossover points along with impedance curves to figure that out. I remember measuring one of these and it dropped to .8 ohms at one point.
The car audio idea is not crazy. The old Orion HCCA or SoundStream Reference amps were capable of 1/2 ohm loads. We actually ran a few speakers in living rooms with surprisingly good results, but these amps require big current. You would need 14+ volts and you wouldn't get away with a cheap power supply.

As far as the Andromeda comment vs the Aragon. The Andromeda II or III would not drive this either, only original Andromeda, if that is what they compared the Aragon with, I still understand it. The Aragon had better midrange than the Andromeda. The Andromeda was so controlled that an under damped speaker sounded week on bass and it was a lean dry sound which the emit tweeters would sound very fast, but very dry. I wouldn' like the Andromeda on these speakers. If they thought the Aragon might drive them and were a Aragon dealer, I can see them sending you that way. The original Andromeda was stopped being manufactured in either 82 or 83. You were probably looking at one of the non Bongiorno amps. The sounded quite nice, but did not have the current capability.
The original Andromeda ran on 50 volt rails. Jim himself called it an arc welder.

When I mentioned car audio, I was really thinking about the low impendences (which are similar to car audio), and did not even think of using car amps, but now that you mention it..........
The kapppas would sound great with a Phoenix gold 450 or Zapco running them for sure.
I have alot of respect for the musicallity of some of the car amps.
I own some premium 12volt products myself.
There are some truely excellent car amps on the market, as refined as any home amps.
As far as sound quality goes, I would give the advantage to DC current!
I would worry about the electrical conversion though.
Ac to Dc.
May introduce some noise and negative effects.
Not really sure.

Stereophile review on the original Andromeda. Stereophile says to use a impedance compensation circuit on certain electrostatics, because they can show a dead short to the amp, but the don't have any record of Andromeda's not handling it. Its all in the article above.
Jtiesel2. You can hunt one of these down for around $350.00 or so. I'd park here on Audiogon and on Ebay. One will come around. Give it a try. You can sell it easy enough. If it works out. I can suggest some people to mod it. A few parts in the right places will take away the dryness I was describing. Good luck, Tim

Thanks so much guys. Pro audio has some good looking stuff just not finding exactly what I need being sold used on any of the regular sites at the moment. Wish me luck in repairing the foam woofer surrounds!!
