    Subwoofer sizing question

    I was wondering - Is there anything wrong with using 2 different size subs? I was thinking that different sized subs have different frequency responce ranges, so why not have 2 or 3 different sizes (ie 8", 10", 12") to better produce as large a frequency range as possibile?

    Also, what about 2 subs from different manufacturers since they also would produce different respopnse ranges as well as vastly different sonic signatures?

    Well, it's not really worth the time and effort. A subwoofers job is to reproduce the bottom 2-3 octaves of the audio spectrum. Most people (myself included) have there sub low pass x-over set between 60-100 hz, so having a sub that plays up to 1000 hz (which a 12" will do) is worthless.


    Having subs from different manufacturers is also a bad idea, it would be a tuning nightmare. The total output would be the sum of the two subs and their sonic signatures would be blurred together.

    Yep, waste of time. The only way it might be worthy is if they were different enough that you'd use a crossover network that seperated the frequencies sent to each one. Sort of a mid-woofer and a subwoofer.

    If you just want a lot of bass then get the biggest or a set of the biggest that you want to dedicate the space for. If you're going for the best sound then crossover tuning and gain control will get you there.

    Yeah, like if you were to run a 18" or larger driver up to 50 hz and a 8" from 50 to 100 hz.
