Axiom Home Page Forums General Discussion Home Theater Changes to EP500?

Nope no BD here. I’m so far behind the times I don’t even own a cellphone (no kidding). It pisses my bosses off to no end but not a thing they can do about it.

Yep that is my system, though right now I’m only running 2 x M80s, 1 x M22 and 3 x QS8s and 1 x EP500 for a 6.1 system. I’m being lazy about buying a projector and screen so I can use all 3 M80s up front again. I’ll eventually get an Oppo BDP83 but for now I’ve got a couple thousand hours backlog of standard def stuff to watch so I’m in no great hurry. Plus I like to let early adopters like you work the bugs out first.

I am having a problem boosting the 40HZ to 80 HZ range on the EP500 when playing music. Since the new design has no trim control (replaced with subsonic filter)I need advice on how I can boost that range. Everything I tried so far seems to boost the low end then it sounds like too much bass. The R772 does have a parametric equilizer but I have it off. It has 5 equilizer bands were you can increase the dB will this solve it?

How do you know your needing to boost those ranges, are you running graphs to determine, or just using your ears? A flat frequency response across the entire range is the most desired. Without proper placement, room treatments, multiple subs, etc. you may just have to live with what you have, welcome to the joys of subwoofers.

Well I called a high end stereo shop to come out and calibrate everything for the best placement. So if they cant do it then I dont know.

You have to remember your room is the most important part of your system.

Hope it turns out well!

If I lived near you, I'd do it for beer.

Im sure in some alternate universe this is ruler flat, but the is the reality that we deal with.

You either have a placement/room issue, or possibly you are used to a skewed bass response. Most likely its the former.

Let us know how the calibration goes.

The thing about calibrating subwoofer is that it's very hard. It's hard because it's tricky to get a good reading with an SPL meter, because some Avia disc's calibration was wrong, because the receiver plays a great roll, because the room acoustics come into play so much, and because it's hard for humans to figure out non directional sound.

Before the high end guys come out to do the calibration, ask them how they are going to do it. Are they going to just sit in one place and use RS SPL to calibrate it at 75dB across the board?

Do you have someone that can help you with a sub crawl? I know it's a pain in the butt; however, this may be the single biggest bang for the buck adjustment you can make with your sub.

You can use Flight of the Phoenix to generate *LOTS and LOTS* of LFE while doing your subcrawl. Or you can use your pink noise from the AVR.

If you get sick of trying to calibrate it, you can always buy another sub!

Oh, one more thing. How are you listening to your music? I think you mentioned that movies are fine but it's not when listening to music?

What do you use to play your music?
