Axiom Home Page Forums General Discussion Technical Questions Amount of gain on EP500 volume control

I was told that the trim setting depends on, or a lot on your room. The issue I am having with my 500 is that I'm lacking the bottom end. This isn't really that new in the sense that I've been testing different placement hoping for different results and that I'm very limited with the amount that I'm actually able to get up and about. When I first got the 500 I was totally happy with it, lots of bottom end "boomy bass", just overall good LFE, and back then I had my trim setting to "flat". I listen to a lot of music with bass in it and am well accustomed to certain songs, now when I'm playing them I get a noticeable "thud" sound with some bass. It's improved slightly when the trim is set to full, but it just doesn't sound as it once did.

Cam, better check for stuffed animals in the port.

Who you talkin' to?

Me?

He did say Bob, don't worry we are here to help, why ya getting all excited.

Because we are never much help?

Does soft plastic and air, with a name and blonde hair constitute a stuffed animal?

wheelz999 - I'm in a similar situation as you as I don't feel that I'm quite getting the performance/response out of my 500 as I expect. My problem was that the 500's original amp had a faulty volume control and I couldn't calibrate the sub to match the same level as the other speakers. I didn't realize this to be a problem for some time, though, as I just recently had the opportunity to use an SPL meter (thanks to jakewash) to calibrate. Before that, I simply ran the 500 extremely hot and didn't realize (due to my ignorance) that my sub was playing too loudly. Now that it is properly calibrated, I don't feel it's response is "quite right". Keep in mind - I probably don't know what "right" is and that may be the problem

I'm going to keep working on it. And, much to appreciation, I'm going to lean on the expertise of jakewash to keep helping me out when I have the time.

Good luck with your tweaking.

Whenever I calibrate our 600 with the rest of the system using the SPL meter it seems a little too weak for me so I run the sub about 3-5 db's hotter than the other speakers, and then sometimes will bump it up or down a little depending on the material being played.

Even after exacting calibration with the SPL meter you may still want to tweak the system for your ears, after all that's what really matters.

That's one of the benefits of the BFD. I like running the sub about +6db hot on the extreme low end, with a house curve bringing it slowly down to +0db. The "boominess" seems to hit me around the 60Hz range, and by that time I'm down to +0db, while still retaining the boost at the extreme low end.
