you haven't specified what your amp is, but i'd be very hesitant to run speakers a and b at the same time--you're effectively halving the impedance load that the amp sees, which could potentially damage it and will likely affect performance.
Dual Sub-woofers paired into two sets of speakers - connection option.
I have 2 sets of speakers connected to my power amp A and B speaker outputs.
I also have two SVS SB1000 pro sub woofers hooked up to my pre-amp mono sub out with a RCA Y-splitter.
The subs have speaker level left and right input.
I would like to hear the supposed advantages of stereo subs.
Would it be feasible instead of using the mono sub out to connect from each speaker to one of the sub speaker level in inputs? Speaker A would go to sub speaker level Right input, Speaker B would go to sub speaker level Left input.
This way I can still switch listening from Speaker A or B and still have subs.
Would I run into any problems if I had both speakers A and B active at the same time? (I'm inclined to think its OK as the sub speaker level Left and Right are designed to both take a signal at the same time if hooked up to just one set of speakers).
I'm thinking I'm OK but I'm always overly cautious when wiring up something that is unusual.
Thanks in advance to those more experienced than I.

@livinon2wheels Thank you for your very thorough response. Maybe a little over my head but I do get the gist of it. Really just want to know if I am opening up the possibility of damaging anything (as @loomisjohnson noted, possibly if running both A and B at the same time). I'm just curious and will try with just one speaker set. I was of the understanding that connecting a sub up to the speaker level input from the main speaker yields a more coherent signal a it is the exact same signal as the speaker see's but presents virtually no extra load, the sub still does the power amplification and cross over processing. Yes, try it and listen. My ears will tell me. I like experimenting. |
Thank you for your response, My power amp is a Parasound 2350 class D, 600 watts x2,
Minimum Speaker Impedance (Output A+B)
I like to experiment, but am very cautious. I was of the understanding that connecting a sub up to the speaker level input from the main speaker yields a more coherent signal being the exact same signal that the speaker see's but presents virtually no extra load, the sub still does the power amplification and cross over processing. Am I correct on that? Think I'll try with just one speaker set and let my ears inform me. |
@tunehead Correct in your thinking. High level connection will pass along the sound charateristic of your amp. Punchy amp = punchy sub. It uses a small signal and uses no extra load. Highly recomended for stereo set up. |
your parasound is a high-current amp designed to go down to 2oHm, so unless your speakers are ridiculously demanding i wouldn't expect it would have trouble driving both sets of speakers. i also see no problem with connecting one or both subs via the speaker level input on your amp. that said, i'm not sure whether you'd achieve better sonic results with two sets of speakers and/or whether your two subs would sound better via speaker level connection vs. your current lfe connection--i suspect it's system-dependent. rel subs, for one, tend to sound better with speaker-level connection; others may not. |
