I wonder what improvements can be made with a mini DSP? I havent even read up on this, I need to check it out

Blackmambakila's Avatar Blackmambakila 02:05 AM 01-05-2014
Well I did some reading on mini DSPs. Interesting indeed but I probably won't get one for this setup. I think REW would keep me busy for now. Def something I'll get into for the future though

Eq should only be applied as a last resort. Your graph looks pretty good, I would leave it alone.

Anyone have a link to help me get a whole setup.

How do these graphs help u determine where to put acoustic panels

http://cross-spectrum.com/measurement/calibrated_umm6.html

Everywhere I've read said to get it from these guys. They calibrate the mic before shipping to you and send you the data on a USB drive. I just got mine yesterday. Haven't hooked it up yet. The UMIK-1 might be a better choice, but those have been sold out and won't be available until mid January.

Yeah that's what I figured, no use going through hurdles if not needed. I can honestly say though that my room pressurises so much now that it's even hard for me to tolerate without feeling woozy. Can't ask for much more at this point, PSA def met my goals and took me even farther than I planned biggrin.gif

Really you'd be fine with either one, even if one was off by 1 or 2 dbs it wouldn't make any difference from keeping you from using REW accurately. Good luck on measuring and don't pull your hair like I did lol

Thanks. I'm actually really excited to take measurements after seeing your graphs. When I run Audyssey it feels like it takes away my bass completely. I just shipped back a Denon X4000 with XT32 & subeq because I did not like the sound. Especially what it was doing on the low end. I am going to use the REW to find the best positions in my room for two XV-15s and then optimize with room treatments and minidsp.

I also picked up a Pioneer SC-75 so I can make adjustments to the PEQ after running room correction. Something I couldn't do on the X4000 without Audyssey Pro.

Sounds like a good plan! What's the size of your room your working with?
Slingblayde's Avatar Slingblayde 10:09 AM 01-05-2014
Are you guys measuring with the Mic in a horizontal or vertical position, something in between, or does it matter?

Approximately 20x15x9 with two large opening to adjoining rooms. Basically a colonial with a first floor open floor plan. Roughly 9000 cubic feet to pressurize. The large openings behind and to the side of my main listening position make sub placement rather difficult. Basically looking at front wall placement either in the corners or inside my main speakers.

In our case, the last set of readings was done with the mic laid out in the horizontal position. Never gave it any thought as to making a difference or not.

(good question)

Cross Spectrum will not ship calibrated mic outside of the continental US.

International customers:

*Please be aware that we are no longer shipping UMM-6 microphones to non-US destinations. If you order a microphone using an foreign shipping address, your order will be canceled and your payment refunded. We apologize for the inconvenience.*



This unfortunately... applies to me and the Dayton UMM form PE is likely my only option. So, can these calibrated mics be used in unison with any AVR...my Anthem uses its own ARC designed software...how can I be certain it will recognize or not conflict with the Dayton UMM-6 program?

Any advice on how to proceed would be welcomed....smile.gif

Mic should point to the ceiling. And use the 0 degree cal file

My PSA-XV15 will be here tomorrow. It's been a long wait. I thought I was going to have a heart attack waiting for this sub to get here. It's X-Mas all over again biggrin.gif

I think only the UMM6 is not shipped outside the US because earlier versions were failing and getting them replaced was a pita for customers outside the US. CSL ships the UMIK-1 outside the US, but those are backordered for another couple weeks.

You'll def benefit from when you get to measure, for now looks like you've got a nice setup. Whenever you get a chance snap a couple pics, one of the front side of your setup and also the rear side. smile.gif

Enjoy, I sure am..........And I only have a single XV15 in a 23x16x9 room. Not the 2, 3 or 4 like some have. cool.gif

It appears, that I might have the opportunity to buy a use XPA-3 for a really good price. I've PM the seller, and I am hoping he answers back promptly. If I am able to buy, the XPA will be powering my front 3, and my pair of Outlaw M2200 will be powering my surround. The Outlaw M200 left over, I am not really sure what to do with it. I'm probably going to put it in storage until I can find another M2200 or M200 for the surround back biggrin.gif

Once the 4520/3313 are up and running, hopefully I'll find out what that feeling is.

yep Beeman, youll def be in good shape especially since you know how to dial everything in. its all worth it when your all done and go to fire up some demos, then comes the Grin biggrin.gif
Joshjp's Avatar Joshjp 01:35 AM 01-06-2014
How much more dbs do you get when you go from 1 to 4 subs? Is it 10 db more asuming they weee all double stacked in both front corners?
BeeMan458's Avatar BeeMan458 02:09 AM 01-06-2014
My understanding, colocated + corner loaded is 12dB * 2 = 24dB but that's on the back end not the front. What's up? As in what are you planning?

I also own a Pioneer Elite avr and use PEQ. Running the PEQ after MCACC is what I have determined is the best way to use it. I found that running a 3 position standing wave calibration is vastly better than running 1 position. I Use Chase sub and a Behringer I Nuke 3000 which seems to be a nice combo. Enjoy your sub/s.

Located close behind your main listening position.
Brian Fineberg's Avatar Brian Fineberg 08:28 AM 01-06-2014
also if placement is flexible the "sub crawl" is the best practice...

place the sub at the main listening position (literally at the seat) and then put on bass heavy music or movie...then crawl around the room (near the walls) to find where the bass is the loudest most prominent. this will let you know the ideal place for the sub (please note....its is almost never the best aesthetically pleasing place smile.gif ymmv)
