Need help with a Sub here.

kvillella · 08-07-06, 05:50 PM

I just recently bought this on ebay:
Sony Dream System Sub-woofer Model SS-WS5
and it doesnt have a power in/out cord. What exactly does this mean? does this mean that it runs off the power from the speaker wire? I am really confused about this? Can someone please answer? thanks

If it doesn't have a power cord, that means it's a passive subwoofer - in other words, it's dependent on your receiver/amplifier to power it. I'm pretty sure that means it won't work off the LFE/sub-out channel from the receiver/amplifier - you'll have to connect it to one of the speaker connections.

AHHH, ok, ill try that, I think my recevier has a sub R/L speaker connections. you think it'll work?

It is a passive sub and won't work with the LFE out from your AVR. It needs an amplified signal, so you have to connect it to your mains output. I can't find anything else about this sub, so you have to look at the connections and controls and tell me what you see.

All it seems to have is a pair of spring-lock terminals. It needs an amplifier to drive it.

I thought the AVR would act as the amplifier. Am I wrong?
btw, thanks for the help.

the AVR only supplies a low level signal out of the LFE output

ok, thanks for all your help.

Most regular receivers don't have amplification for the subwoofer. Most subwoofers are powered, with the amp on the back. You got a passive subwoofer, no amp, that came from a HTiB system that ran off of an amp channel in the system's receiver. You can run it off of a channel of the regular receiver, but then you can't hook a speaker up there. Basically it's junk unless you pick up a separate mono amplifier to run it.

I'm wondering the same thing. I've got a STR-DE915 amp in my bedroom connected to my computer. I'm only running two fronts from it.

If I get this sub, would I get more power from connecting it to the terminals where the fronts are connected, or should I connect it to the rear channels, or the B channels (and run A+B)?
