Help powering pair of Infinity Kappa 9's
by jtiesel - 9/5/10 4:24 PM
I own a pair of Infinity Kappa 9's that I am trying to find power for.
Owners Manual Specs:
Nominal Impedance: 4 to 6 ohm (recommends amps that can go lower)
Power Rating: 60-340 watts RMS
Efficiency: 102 dB SPL @1 watt, 1 meter
Crossover Frequencies: 80Hz, 800Hz, 4500Hz
Frequency Response: 29Hz-45kHz +/-3dB
1x - SEMIT Supertweeter
1x - EMIT Tweeter
1x - 3" Edgewound Voice Coil Polydome Midrange Driver
1x - 5" Polypropylene/graphite Diaphram Polygraph
2x - 12" Cast Frame , L/C Tuned Woofers
These speakers are 5ft tall and require lots of power to run. In the manual it says that each speaker can be bi-amped and recommends giving the most power to the woofers.
I'm looking for people who have experience powering heavy duty speakers to recommend a budget (I will be shopping ebay, craigslist, and sites like overstock.com) solution for the power needs of these speakers. Any thoughts, experiences, or words of wisdom would be much appreciated
