Does anyone know if it would be problematic to my amp if I were to hook up a Polk PSW10 in parallel with a set of tower speakers? I would like the speakers to remain full range, so I don't want to run the signal to the sub, then on to the speakers as that would engage the sub's x-over. This is a late 80's separates system, pre-amp/amp, 2x100w made by Harmon Kardon, no sub pre-out. I'm just attempting to help out on the bottom end a little. I'm pretty sure the amp is 4ohm stable, (I'll check), so I'm guessing this won't be a problem. Anyone have any idea what kind of impedance the speaker-level inputs to a powered subwoofer would show? the speakers are large 3-way towers, (made by JBL, tweeter, 5" mid, 12" woofer).


Not looking for a critique of my choice of equipment here! I know that Polk is a small underpowered sub, but this is just for music, to fill out the lower end, (and I'm paying $50 for it).

That should work fine. The input impedance on speaker inputs(on powered subs) is usually designed so it doesn't show the upstream device(receiver here) any actual "load".
