Axiom Home Page Forums General Discussion Technical Questions I got me an SPL meter

Graeme,

One other thing you might like is to bump the center channel by ~3-4 dB. It helps with dialogue intelligibility on most movie soundtracks. If you like it the way it sounds, there's no reason to change it, but bumping the CC is a common adjustment after you equalize the rest of the speakers.

A sub 9db louder than rest is way too hot, I have mine 2db and my center channel sits about the same 2- 3 depending on the material.

I think how hot you set your sub depends a lot on your in room response curve. The meter is biased towards the loudest frequencies in the curve. In my case, I have a +20db peak around 52Hz.

I find that I have to turn up the EP350 a lot (from 9 o'clock to 11:30 on the dial, +15 clicks) to get good rumble in movies. I havn't checked how many db that is, but it will be interesting to see how things change if/when I tame that peak.

Thanks for the advice, I will make the adjustments when I get home from work. I will also try to get those pics of the subs back panel, As I don't think I have it right.

Well I have adjusted the CC a couple of DB more than the speakers, so far it's good.

I have the pic of the Sub's rear panel, can you take a peek and let me know if I have it set correctly? On the AV in the sound setup menu, I have the meter set to the max position. Maybe I should bring that back inline with the speakers?

I would turn the LP Filter up to 100 so as to not have it interfere with the avr crossover, other than that it is up to you and the SPL meter to decide if the volume level of the sub is set as loudly as you like it, 5 is a good place to start if you think it isn't loud enough just turn it up a little more. I would also take a guess that the other input bypasses the LPfilter on the sub leaving you only the volume adjustment working.

Thanks for the reply, I wasn't sure if I had it connected right. I still have to get a decent length of cable so that I can do the Crawl. I have tried several settings but it always seems very course, the port noise is the most annoying at high volume.

Port noise is always a problem when approaching the limits of the subwoofer.

I agree, set the crossover to 100 as to not interfere with your receivers crossover settings, usually 80hz.

Graeme, just looking at the picture and not having access to the manual(if you have it the connections should be described), I'd be inclined to agree with Jay that the other input labeled "XOVER INPUT" is the one intended to be used when a receiver is doing a crossover. So switch the cable to that input, which then bypasses the internal sub low-pass filter and makes that setting on the sub control irrelevant.
