It has connections for Subwoofers. Do these Sub connections provide 'amplification' to the subs, or do the sub need to be a 'powered' subwoofer?

The sub out is only preamp out. You will need a powered sub. I recommend about a 250 watt, 12" sub. My sub is a Polkaudio 12" and it blows the walls down. I think I paid about $299 for it.

Hi CritiKiL, you needed a "powered" subwoofer. to have an amplification. -Ely

No, it can't power a subwoofer. The only output is an RCA connector so you have to use a powered speaker.

The description says "Optimized for use with subwoofers" I'm guessing it's not high fidelity. My sub sounds fine hooked up to it, but if I was going to hook up some regular powered speakers, I'd buy something that's advertised for that purpose.

You will need to install an amplifier to power the sub woofer. Once you install the amplifier you will need to run an RCA from the sub woofer output to the amplifier.

The answer is yes.You can connect both: powered and non powered subwoofers.

Although I am not using it, there are connections for the periferal speakers on the back of this subwoofer, which is powered sufficiently.

The receiver does not have speaker terminals for the subs instead it has a sub out which means that the output is preamp so passive subs won't work. Active subs (powered) are solution to the power need to the amplifier to reproduce deep low frequency. If you can't part with the bass module, this receiver is not for you. Otherwise just replace the bass module with a powered sub just realize it probably can't compete with the Bose bass module.

an "lfe" connection, or "rca" sub imput. i had to put a inline low pass filter on my setup to drown out the bass from the spoken word. in lamens, its just a big amp with a cappy filtering.

This unit only has pre amp sub outputs. There are 2 outputs for those who prefer having 2 subwoofers in their system.

Subwoofer output is line level (i.e. non-powered). You have to buy a powered Subwoofer. So to answer your question, no watts are put out to the Subwoofer.

Yes it is only a speaker. All subwoofers need power via an amp. I bought the boss 1100 watt amp it recommended and it is a great combo.

I have a powered sub that accepts speaker-level input, and it works great attached it to the "B" output (I am only using the "A" output for my main speakers).

You do not power a sub through preamp. Your sub is powered when you plug it in a wall socket. the recieverdoes not drive the sub it drives itself whereas, the other speakers are driven by the receiver which can notgive enough power to 5 or 7 speakers they each want. It is better to over power than underpower speakers.

Probably worth buying a more advanced subwoofer.... Thought mine was but unfortunately my RCA connection to my subwoofer did not work so I tried connecting my subwoofer to my two front speakers. Don't know if that is the proper way but that thing is delivering a thumping bass

it does not connect to a subwoofer. I think these speakers are good by themselves. It has a knob for increasing the bass volume.

You will need to purchase a cable seperately. It did not come with a subwoofer cable.
