For speakers:
Frequency range. The lower the first number and the higher the second number, the better.
50hz-20khz (20,000hz) is good. 100hz-12khz is bad.
Sensitivity or SNR: Over 90 is good. Below 89 is bad.
Wattage: Remember, wattage is divided among the 6 speakers. So if you get a 100watt system, that means the sub probably gets 25 watts and the rest get some miniscule amount. Higher, the better, though not necessarily louder. |
