I have spent hours trying to get a good concept of how a receiver handles bass and LFE. Does anyone know of a good link that explains this or can you help me here? If my receiver has a crossover frequency of 100hz what does that mean? Also if the crossover of my sub is set to 60hz than all frequencies above 60 are directed back to the mains? (even with the mains set to large?) Isn't the LFE lower than 60 hz? I have good sized floor speakers with 12" woofers. Should I set the mains to large? My sub is a little 8" Aiwa with a 60 watt amp. Is there a use for this in my setup? Or should I use it for a door prop?
