Very first post so pardon if this has been asked and answered before but had a rw12d klipsch hooked up LFE to a denon e 300 and sounded OK but had some dead spots so I got an sw450 to help fill the gaps. Actually got 2 sw450s but never opened the 2nd one, Nebraska furniture mart had them on sale for 200 bucks a piece and I couldn't help but to buy two. Anyways I have them hooked up via a y adapter off my single sub out and it seems to have less bass than before. The main sub is still in its original pos and I raised my gain to comp the signal loss I figured I'm getting from splitting my output from the sub out but just seems like I have hardly any output. Any suggestions are welcome.
