I ran the scene again as well and this time turned down the curve 3 dBs per octave. I had a LT boost of 13 dBs at 10 hz and that what set off the breaker. Playing it at reference with subs calibrated flat and LT boost at 10 dBs or about an octave lowering of the F3 was just fine but the screen was moving so much it blurred the image a little(shaky cam effect). You have the same displacement as I do but my room is 1500 cubes.

I was afraid I was gonna get that nauseated feeling again..

If you are popping your breakers at -13 it might be time to replace the breakers. I heard they weaken the more they pop.

This. The more they trip the weaker they get and will trip more often. Which could actually lead to the breaker failing completely and causing a fire. It might be time to replace the breaker.

Reference level (0 dB) is identical volume for you and for MK, room has no impact (unless you have not set your receiver up). I think some people find -15 to -10 getting too loud if your speakers are low end/commercial / dome tweeters. You need high efficiency pro theater speakers to really listen loud without distortion.

Not true. Not every receiver calibrates to true reference level. I have gone through 3 Denon receivers and only one of them calibrated to where 0 db was reference. The other 2 were WAY too loud at 0 db.

I'm wanting to demo Pacific Rim in 3D this evening to my buddy and I was wondering if anyone knows the best scene to also show off the capabilities of my SVS PB-12 Ultra sub. Something that truly shows some awesome bass. Thanks!

You're supposed to do it manually. Just in the past few years receivers have done it on their own....

Not for that ported sub. Pacific rim is perfect for it.

No problem. I was just hoping someone would know a specific scene that rocks the bass in Pacific Rim

That's good to know, my microwave breaker pops fairly often.

The little Japanese girl flashback scene hits the hardest I think. And it's just a damn good demo scene. The opening scene is great too but it doesn't dig as deep from what I can tell.

I'm talking about receivers that used Audyssey MultiEq calibration. One of those models (AVR-888) had that feature, but still didn't put it at reference. Additionally, aren't there some receivers out now that don't even utilize the -X db volume setting?

But notice where each of my subs was plugged in he ask what was the specs of the subs amps. So I showed him the specs at speaker powers website. Then he said I should be fine, not unless I'm really using all that power then yea it'll trip. But thing is that he said I could go with 30amp breakers. But I know he wired it with 12 gauge. Ain't that to small? Anyway, Pop told me something similar too. That if the subs are capable, then it takes a lot of power to produce in the low end region. I don't know, maybe I should add filters.

While its not code, you can prob get away with swapping the breakers to 30a if you're using 12gauge wire. Understand the risks here, 12g solid wire is not rated for 30a in wall, but if its just quick peaks from subwoofer amps only, you're not likely to ever see an issue.

Thanks notnyt.. Well guess I gotta call my electrician back and swap out the breakers..

Over the weekend I had a chance to watch the new Robocop and lone survivor. Although I really e njoyedd Robocop lone survivor was the better movie all the wsy around. Especially in the bass department. Have not heard such well placed audio in my theater since enders game. It lives up to the hype for sure.

It's the duration that's popping your breakers. You have four amps each trying to pull more current than your breakers can do, and for almost a full minute. As mentioned before, you really need 30A runs to have those S2 live up to their potential on scenes that demand it.
