Powerslave Posted February 10, 2014 Report Posted February 10, 2014 Have the polk 660 amp with kicker cs65. Amp is rated at 75dB and speakers at 90dB. Do I have any issues here?
Powerslave Posted February 10, 2014 Author Report Posted February 10, 2014 Yes. Amp is pushing 75 w x 4 @ 4ohms and speakers are rated at 100 rms. But was wondering if the dB's were an issues with them matched up.
Krakin Posted February 10, 2014 Report Posted February 10, 2014 You are looking sensitivity, at least for the speakers. The way that specification is found is by sending only 1 watt and measuring the decibels at 1 meter, nothing to do with the thermal or mechanical limitation of the equipment. Have you already bought these speakers?

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.
Powerslave Posted February 10, 2014 Author Report Posted February 10, 2014 Yes I have. Not good? But didn't know if an amp rated at 75db would be ok with 90db coaxial speakers. Or should I not worry about that?
Krakin Posted February 10, 2014 Report Posted February 10, 2014 They are fine, I just ran into an issue with that huge glob of flue next to the dust cap on the cone. I'm sure if you get them you will be fine, it took them 2 years before something happened to mine. Right after the warranty lol.
