My setup..
Denon POA 2800 ( amp )
Sansui AU 717 ( pre )
Sansui TU 717
Klipsch Heresy
Vandersteen 1

Anyway...how do or can I hook a sub ? No jacks on the Denon....where on the Sansui ? Or just leave it as is....?

The Heresy gets down to 50 hz, right? Do you really need a sub, or is it just something you want to try? Is this for music only, or home theater use as well?

Just asking - wondering what your goals, thoughts are.
 
Get a sub with either R/L line level inputs or R/L speaker level inputs. Outputs are fine but those re the minimums. I've not seen any speakers that can't benefit from a properly integrated subwoofer.
 
It's not imperative that I have deeper bass...really just wondering HOW I would hook up a sub in that scenario...plus..sometimes a little throb is in order...
 
OP---Most subs can be hooked up from the amplifier speaker terminals. You run wires from the amplifier speaker terminals to the sub, then another set of wires from the sub to the speakers. The sub probably has a terminal block that allows this.

That's a nice way of doing it, but I don't know about "most subs" as it seems like a lot of them don't have speaker type connections, only RCA. I've owned some of both types. Actually, if the sub you have has speaker inputs and you have a A/B speaker switch on your amp, then running the sub on the "B" speaker switch is the way that I'd probably go. This way, you can toggle that switch to turn the sub on and off. You might not every have a reason to turn it off, but it's nice sometimes just to be able to toggle that switch to quickly hear just what the sub is doing...
 
Your amp has A and B speaker connectors. I would get a sub with speaker-level inputs. Speaker-level outputs are not needed, unless the sub has a high-pass filter in addition to the usual low-pass 'crossover' provided (rather unusual). Connect the speakers to the A pair on your Denon amp, and the sub to the B pair .If you instead decide on RCA inputs, get a sub with both L and R inputs, not a sub with just one LFE jack. Either way, at a minimum you will want one knob for volume level, and another for crossover frequency. Try a crossover setting of 50 Hz for the Klipschs and 40 Hz for the Vandersteins. On a typical 'classic rock' recording, the sub should add some weight to the kick drum, and not really do much of anything else, most of the time.
