Does a woofer with line-level outputs essentially allow two extra speakers to a HT? - AVS Forum

In regards to subwoofers that come with line-level outputs -- how do they work? Does it allow you to connect an assumed FL and FR set of speakers?

And even deeper than that -- if my sub is connected to my receiver, is all the audio information being passed through the RCA connection and the woofer only plays the low-ends? So the data would be there to pass through to other speakers?

Going to read up on line level outputs but would love to hear some use-case scenarios.

Thanks!

It would be helpful if you would tell us what sub this is.

Just in general -- looking at subs with line-level outputs. Or "Speaker-level" outputs rather. One example:

If your subwwofer is connected to the receiver's subwoofer output, it will only receive sound in the 0.1 (LFE) channel plus any redirected bass from the other speakers. The receiver's crossover will eliminate, effectively, the higher frequency sounds from what gets sent to the sub. That's pretty much the point of a crossover . . .

Sounds like a HTIB sub, though. If so, the sub itself may have an unbypassable crossover, and stacking it with the receiver's crossover may result in a frequency range that is too low in sound pressure level.

Ah yes that makes sense -- it's probably meant to pair with a HTIB system. So in a receiver situation those ports are likely useless. Thanks!
