2 subs

[Brentlee24]

I know 2 subs sounds better than one, but what if it's a good sub with a crappy one. I have a svs pb2000 hooked up. I also have a sony sacs9 10 inch lying around. Should I stay with just the good one or hook them both up.

It is generally accepted that the weaker Sub will limit the performance of the better performing Sub. If you push the lesser to perform to the level of the greater, you will experience increased (perhaps audibly) distortion and possibly bump up against the actual mechanical limits of the lesser Subs performance (thus risking damage and outright failure).

Agree with ryan.
Short version...don’t do it.

I'm about to find the answer to this question today. I have the PB 1000 now but taking delivery of the PB 2000 Pro today and I'm gonna try to use them together. SVS said it should be just fine because they are both ported and tuned similarly. Gonna be an interesting experiment. I have never had dual subs so I'm excited to see what it sounds like.

Mixing different subs is a lot more diable with SVS's ported subs than other brands. SVS's limiters are pretty strict so they can't really be driven into heavy distortion. So they just stop getting louder. Most brands don't behave like that in lower-cost models. That Sony will start to sound real ugly before it compresses total output. I would not mix it with an SVS sub.

That's what I have heard over the last week of researching. I'm not expert in subs that's for sure. It's always been an overlooked part of HT for me which is stupid.

Anything by HSU and Rythmik would allow you to use different models within their line up I would think.

Kind of. You can mix subs from these higher-performing brands, but you want to make sure the port tuning frequencies are roughly the same. Also, Hsu and Rythmik still use analog amps. They have pretty restrictive limiters, but if you push them hard enough, they can be overdriven, unlike digital limiters. So if you were to pair one of those subs from something like SVS or Paradigm, you would want the subs with the analog amps to be the more powerful ones.

Don’t mean to thread jack but i recently got my first 7.2 receiver and already had a BIC America 12 F12 sub and recently got a Klipsch R-120sw reference series 12” sub. Can these two be mixed ? I was going to put the BIC in front left and Klipsch in rear right. Very similar specs.
