Spkr level inputs vs. RCA

[calegrant]

I'm setting up a small bedroom system and I plan on using an old reciever I have. It has no sub specific output so I'm looking at just using the speaker level input. How much of a difference in sound quality does this make? The guys at the store say it shouldn't be noticeable, but I want some real world answers.

If you are talking about using the speaker outputs on your receiver to drive the speaker level inputs on a sub, then you're fine. That's what they are made for.

If you're talkng about using speaker outputs to drive a device with line level RCA inputs, you may want to rethink that big time. I'd advise against it.

In your particuar situation I would avoid any sub without speaker level inputs.
