Odd, I know. I'm not ready to call that max. The thing is, though....is it sounds like the limiter is kicking in well below any of the filters. I spent some time on the RTA today listening to frequency sounds, it's been a while.

But then I think ..... shouldn't the limiter kicking in show on the graph? Not sure..... There is an .Mdat file attached for whoever wants to check out the distortion or whatever......


Here's a screen shot of the the filters and graph from REW.

You do realize that trading those xv30's in for a single Triax will be a lateral move in terms of output? However The Triax will yield deeper extension and possibly better SQ. The fact that those 30's are starting to compress at 105 tells me there is something definately wrong with the signal feeding them. Thats why they do not sound right. They should easily hit over 120db even with that amount of eq. Point is I bet you are going to run into the same issue with any sub you hook up.

Have you checked your measuring gear to make sure it is working, especially the spl meter? There is no way you should be compressing at 105 dBs in that range because they can play 20 dBs louder outside within that range! Also, your speakers look like they are compressing in the 90 dBs range which tells me something way off. I now guessing it is not your subs or speakers.

Here is without the mini - dsp in the chain.

Mic in same spot, AVR same settings etc.

Could it be that the peaks are not peaks? eek.gif Since the null is actually still reading the same as when the peaks were pulled down.... Even still the peaks should be a tad higher.

Most likely just some issues I'll have to live with. Pulling those peaks will cost ~10db.

I'll go to rat shack and grap an spl meter. No problem.

It'll be fun to verify my UMIK-1 I got from Cross Spectrum is properly calibrated in every area but the SPL meter, since they don't calibrate that one line.

Is there a limit on the length RCA cables one should use on subs?

That is still way low for max output...the xv30f is rated 119db 2m rms outdoors, add another and you should be seeing 125db. I would think 125-128db in the mid bass is what you should be seeing at the LP. You will know it when you are at those levels because when a sub system is approaching 130db it leaves you gasping for breath not disappointment.

25-30ft is approaching the limit of RCA, then xlr connections should be considerd. have you checked line voltage? maybe the amps are starving for power.

I was thinking of turning up the sub amps. They're at ~ 3 o clock.

Any idea what line voltage is supposed to be.

Man that is crazy...I have my subs at 2:00 and at 0 on the Yamaha they are hitting 128-130db according to the shack meter.

I would put a volt meter on the lines you have the subs hooked up to and see how much the voltage drop is when they are turned up. You should get a reading of 120volts. being all your speakers are compressing makes me think you might have not have enough juice from the wall.

Oh the A/C power lol.... I thought you meant the line voltage from the AVR RCA out!

I just had a dedicated line installed for the subs. 20 amps. Maybe the surge protector (which is new) is limiting them. It's only a 15 amp..... A long shot given the circumstances, but I'll check it out.

When you test your SPL, how are you doing it? Test tones with just the subs or what?

I have -10 pulled out on the AVR. I like to be able to turn it up on some movies.

At least that's been the case. Might change once I get things dialed.

In any event bumping up the trim on the AVR during these db sweeps gets the same result as turning up the volume on the AVR.

Turn up the volume, peter out. Turn up the trim, still petered out. I'm hitting a wall somewhere.

The lastest test was with music...back when i just had the dual xv15's i hit 132db with a rew sweep at 30hz. take note that was with the 12db peak at 32hz.

Yep, and believe it or not it's dead even with my UMIK-1 MIC coupled with REW.

There was a bit of variation playing the +/-3-4 DB while playing the cal REW SPL tone, but on the graphs after running sweeps the max matched every time.

No, I haven't.

I can, easily. Here's my thought though.... doing that is supposed to add ~3 db of gain. I can turn the amp down, the sub trim up to a 0, and still be having this problem.

In other words adding gain any which way is leading me to the same wall.

Correct me there if there's something wrong with that thinking. Very well could be since read all of two paragraphs RE: hooking the Y connectors up.

But you're right.... does seem kind of weird. I do believe I am hitting the limiter and it's at the same level every time, no matter how I get to that level.

Wanna see some high numbers..... darn... looks like I tossed the graph of the mic on the floor a ft. from the subs.

I don't remember exactly. It was literally one measure.

I want to say over 135 though. I'll do another one when I measure again.

Tom and I have been conversing. I sent enough info to him where he should know which direction to go next.

Really at this point all I've got is checking the voltage at the surge protector during a max DB sweep.

if you are losing 22db from 1ft in front of your subs to the LP then then you might want to try moving the seats or subs...again.

If measured at 1 foot then SPL will be down 6dB at 2 feet, 12dB at 4 feet, 18dB at 8 feet, 24dB at 16 feet, in a anechoic room. It shouldn't drop that fast in a normal room on the broadband average, but destructive room modes can actually make it much worse than that at some frequencies.

right but wouldnt you add 12db back into that figure for 1/8 space?

It's in 1/8 space at one foot or twenty, there's nothing to add.

No adding because you are taking the same in room measurements or what Bill just stated. If he is losing 22 dBs at the LP then I am sorry to say but if you want some bass in there it is time for many many sealed subs or a couple horns! 4 GH's sound about right! At this point based on your compression graphs you need new mains and 4 more subs! The easiest solution would be moving the LP closer! Cheaper too!

The LP is ~9' from the subs. This was the best 'slot' if you will to get out of the deep nulls you see earlier in this thread.

New mains? Please explain......

I have three JBL 3677s in a 15x16 ft., with an 8x8 L. I can't possibly see how that is not overkill for a room my size. But I'm all ears....

Yes

In REW there is a tab in the preference section labeled mic/meter. I stick the calibration file from Herb at Cross Spectrum Labs in that box.



I can do it manually, but normally when REW does not have the cal file in that box (if I delete or whatever) it will recognize my USB mic and ask for the cal file.

To calibrate the output to a certain volume I go into preferences sound card tab and select the check levels button, then next. A tone plays. I open the spl meter and set it to 80.

It wasn't quite 22 db. Here's a graph. The blue line is the max sweep, 5db before the speakers go south.

Green line is 1 ft from speaker no eq, gold is the same but with eq.

Set it to 80 only if your regular meter says 80. You need to match REW to your outboard spl meter. THAT'S what you're calibrating.

You're going to find out you've been at 150dB all along! biggrin.gif

My mic is a calibrated SPL meter. My Rew measure, weather noise, graphs, music, whatever, match my rat shack spl meter.

Check them out. I got mine from Cross Spectrum Labs. He doesn't include the calibrated SPL line, but you can grab it from the mini dsp site (maker of the UMIK-1 Mic).

Each mic has a serial number to it, so the SPL cal line is actually for your specific mic. Why Herb does not calibrate it I'm not sure.

Thanks for the tip though!

I checked the AC line voltage at the surge protector and it's 119 on a max db sweep, and it's 119 in any socket I plug it into, so no issue there. FYI the cords that come with the subs say 10 amp on them.

While I unplugged the eq for the close distance test I happened to run a test with the door open-

Who'd of thunk of it-



Not a huge deal but it will save me from having the solid core put in, and lessen the EQ load.
