I just bought a cheapo sub from costco (JLH E-10FB) just to see the effect it had on my front speakers (i heard that buying a sub reduces the amount of bass put on the front speakers). I was hoping that with the sub handling all the bass i would be able to turn up my front speakers louder, as they wouldn't be doing as much. My recieiver doesn't have a sub input but i plugged my front speakers in through my sub (wires from reciever to sub, sub to fronts). It doesn't seem like i am able to turn it up any louder than i could without the sub without hearing distortion. As a matter of fact, it doesn't even seem like its taking any stress off of my fronts. The sub has a dial on the back ranging from 40hz to 180 or something. Does this mean that the sub outputs whatever the dial is set to, and the fronts output the rest? What is the best setting for this? I guess my amp just distorts the signal at a fairly low level and buying a new reciever will be the only way to turn my speakers up louder.
