"Speaker in" terminals - when are they used?

[jpinard]

When are you supposed to use the speaker in terminals (my subwoofer has one for right and left speakers) as opposed to just using the RCA LFE jack? I'm curious if this would be a better for crappy 120 Hz speakers vs using the LFE from my receiver (hookup is from computer).

Thanks!

i think this is so your subwoofer can handle the crossover filter instead of your receiver. i think most people stick with the receiver though.

It's for using the sub with systems that don't have a dedicated sub output. For instance, if you have an older stereo receiver that only has speaker outputs.

These are called High Level inputs. Made for cases then receiver doesn't have it's own crossover. You'd have more crossover control on receiver than using this option. Stick with LFE input

They're also good for receivers with non-adjustable crossovers. The crossover in my old receiver I'm using for my computer system is fixed at 90hz. That's fine for the speakers I'm using now, but if I was using less capable speakers that required a higher xover I'd have to use the inputs + crossover on the sub.

I believe the reason why you are getting suggestions to use the crossover at the receiver is bcos the receiver filtering is done in the digital domain having a higher order crossover resulting in a better roll off making it more efficient. Where as at the sub it is likely that it is done in the analog domain using analog components.
