I'll probably be going with the Ultra, so there will be some additional complications from me not having matching the subs.

Just figure that if I go with an Ultra I'll be out almost $3000 in subs, I don't want to skimp on the last $100.

There is a guide on the mini dsp site that explains how to use REW with a Mac. I use a Mac mini with HDMI.
It took a little bit of time to set up, and a couple of set up steps each time you start measuring, but it works well.

You'll need something to measure your setup with....like REQ. Once you do this you can see if there is any large resonances that need to be tamed. I used the two PEQ's in tandem to flatten out a wide point of emphasis in my room. It doesn't need to be perfect...just help perfect it for Audyssey. The problem with mine I believe is that audyssey saw the drop off for this wide resonance as the actual drop off point in the sub and gave up anything below that. Once I flattened it out the results were startling when followed up with audyssey.

I have REW and measurement gear (though I haven't had much of a chance to play around with it), so I do plan on taking some measurements. All things considered, these subs have pretty decent PEQ's, so I would love to try to get things working between the two instead of buying more gear.

Thanks for tip. I also have Mac mini with HDMi so as Macbook. I will check it out and maybe will get back to you with some questions if I can, thanks again.

REW will not fix Your issue but it will help you in finding the problem areas in the frequency response and Yu can make adjustments manually and REW will let you know the results.

Hey buddy. I just noticed your PM and replied. Sorry, I honestly didn't see it before!

The ultras arrived today, and I'm setting them up right now. Too bad Audyssey pro takes so long to run.

REW will let you see, and optimize, your response before Audysey or any other eq attempts to smooth your response. If your placement is poor and you have a huge null, there is not much that Audysey or manual eq can do to help. REW can help you work on getting the smoothest response possible without any nulls so that your eq can get you the nice smooth response that results in the best quality bass. It lets you see exactly what any change you make with placement, phase, distance changes, crossover changes, etc does to to your FR.

So when i get the mic and i start testing do i need to run Audyssey every time or move the sub while the distance setting stays the same around the room and measure until i get the best response? Or how does that work.

Titan, you can also get the UMIK-1 from Cross Spectrum Labs if you want the best calibration. I don't know how large the difference is, but that's what was recommended to me.

What you should do is the sub Crawl.

Put the sub in your listening position and go around the room to the spots you want to put the sub and measure the output with a
SPL meter using a white noise signal. Put the sub where the white noise measures the loudest.

Also you can use REW at each spot and run a Sub sweep for 10hz-120hz. Find the spot with the shallowest null.

Then Audyssey can trim the peeks.

I have not tried this but it makes sense to me unless others can add to why this is a good idea or bad.

Many subs loosen up after a break in period. I'd either wait to calibrate, or if you must, do it again after you get some hours on them.

You do calibration couple of times anyway a specially with dual subs until you find right spots for them or right mode for Ultras.

Thanks for all the tips guy i guess first things first. Is it really worth the price difference to have the UMIK-1 calibrated from what i see it looks like it is accurate from 5hz to 25khz from the lab. And if i buy it direct it is accurate from 20hz to 20khz. Is this the only difference. I put my PB12+ back in place i am running 20hz tune man this sub has some serious bass output.

If that's the case - if you want to measure below 20Hz, I'd get the one from CSL. It's only a few more bucks.
