How does impedance relate to sound quality in home audio speakers?
I am in need of new speakers for my new home theater system, however as tech savy as I am, speakers are not my forte. The current speakers I run are 8 Ohm impedance, 150W, 91DB Sound pressure, with 36Hz-22Khz range. These are Onkyo Fusion AVs. I need a good pair of slim line speakers, and I have found a few that I like however I am not sure how they compare with my current set.
Can somone please explain to me which of these statistics should be lower, and which should be higher for optimal sound quality.
Thanks!
You want your speakers to handle your system's output power, so you'll need at least 150W speakers.
The 91 dB sound pressure is an indication of the efficiency of the speakers. Higher is more efficient, lower is less efficient. Remember that dB is logarithmic, so a 3 dB change is a factor of 2 (88 dB uses twice the power to sound as loud as your 91 dB speakers).
A key spec of the frequency range was left out, and that is the variation from one frequency to another -- i.e. +/- 3 dB. Ideally, you'd like +/- 0 dB so all frequencies would sound the same with the same power input, but that's not going to happen, so most spec how close they come to the ideal. A speaker with +/- 0.5 dB across the frequency range will sound far more accurate that one that is +/- 3 dB (remember that 3 dB is a factor of 2).
The wider and flatter (+/- 0dB) the frequency range, the better.
Impedance by itself generally doesn't relate to sound quality; you just need to match your amplifier's preference for best results.
But remember that the specs are the manufacturer's specs, not independently certified specs. You'd do well to consult audio review magazines for their test results of the speakers you're thinking of instead of believing the manufacturer's specs. They aren't perfect, either, but they will probably be more objective than the OEM.
