2 sub question

[moreira85]

hey guys, quick question, I have what i think is a pretty sweet set up especially since my wife and I arent in our house that we hope to buy in the spring. i have boston vr3s, boston vr920 center, axiom qs8s for surrounds, yamaha receiver, boston pv1000 sub. Anyway here is my question i have an old sony 12inch sub lying around, i know sony is not known for audio but do you think it is worth hooking up this 12 inch sony in addition to my pv1000????

Smoke 'em if you got 'em.

Multiple subs are more difficult to calibrate, but when done correctly can produce better frequency response in the listening area, specially if it is spread out.

Multiple subs should really only be done if using the same brand/model subwoofer. If using subs from different manufacturers, it is recommended to use a crossover to isolate one of the sub's in terms of frequency response. There is more to the calibration than just hooking up two subs and setting them at the same level.

I would venture to guess one of the subs will give up before the other and can yield wierd noises, especially during extreme LFE passages.

This is true with equal subs, but if you are using two subs and one is far weaker than the other it will introduce interference. If going the dual sub route it is important to have two similarly capable subs otherwise you are limiting yourself to your weakest link.

Lets call sub A the main sub and sub B the inferior secondary sub. Sub A is happily playing the explosion during the movie and sub B cannot keep up. Sub B will likely keep trying to play bottoming out, becoming boomy, clipping and introducing mechanical noise (these are just some examples) thus nullifying the effects of having two subs by not being able to produce proper frequencies at needed SPL to flatten frequency response and give an overall better bass experience.

Edit: The sub master beat me to it .

I am no sub master. I am still a student I always try to keep learning. Thanks for the complement. I like your explanation though. Very good. A bit easier to understand perhaps.
