first off, get a spl meter if you can afford one. its a great investment, and ive never heard anyone say its not worth 50 bucks.

in regards to the LFE input, it wouldnt matter anyways IF you turn your subwoofers crossover setting to its maximum point, meaning if it has a parameter of 30-130hz, you want to set it at 130hz.

your crossover settings on the receiver should dictate what the subwoofer is receiving. this is more important.

a big mistake a number of people tend to do is to have a 'hole' in there LFE frequencies by having crossover points set on both the receiver and the subwoofer.

for example
Receiver: 80hz
Subwoofer: 60hz

you are basically missing the 61-79hz worth of information being filtered out to a void. this is why we want the sub to be set at 130hz or its highest crossover point, and have the receiver do the filtering for you.

does this make sense?
