Re: how to set up multiple subs properly

I'm at a loss of words for a good explanation but technically either way is correct. Commercial subwoofers have phase swithces on them for integrating with the mains and it's always whatever setting sounds best is the proper set up. As you've found there are trade off's to each way, in the end it's up to you.

Try moving the subs around the room. Corner locations help with the low frequencies and a cheap eq like the BFD can smooth out problems.

If you want them set by the book, their levels should be as flat as possible and matched to the level of the mains. This doesn't always result in room shaking or satisfying bass. Adding a house curve to your eq settings can help you get that low end without sounding 'boomy', though I don't know how to apply it to the SMS.

Also, double check the phase and distance settings set by the Audyssey. Sometimes they can be a bit wacko

Sounds good :T

how many db would be the max you would want in a certain scene in a movie. Now I am well aware that you wan't as much 12-16hz that you can afford. But say in the 20-32hz there is more actual sound at 32hz then at 20hz.

Generally speaking in a properly calibrated system, max output from the sub should be 115db at the seat. But that's only if the recording engineers mixed the effect at max level.

You don't have to do it at 115db, that could damage your subs. Just do it at a normal listening level.

yup! :yes:

It'll help you figure out how to set up your crossover range as well. Take a measurement of just the mains to see where they leave off.

If the clip light on the EP2500 is coming on you may want more power but you don't want to over power them either. Do you know the power rating for them? At this point calibrating your system comes down to personal taste but it sounds like you're getting closer.
