A calibrated mic is even more important in the low frequencies. A lot of the non-cal ones drop off at the low end. Looking good there with the latest runs if they are accurate - and of course if it sounds better that's the main thing. As you can see, excellent results from just 4 filters. I'd be interested in seeing unsmoothed or 1/12 results too. The idea with the waterfall is that once a sound is made, it should go away quickly. If it does not, it is reflections hanging around (or indeed it was too loud in the first place). The waterfall shows how quickly a given frequency decays in the room. Less than 300ms for the sound to go away is supposed to be something to aim for, so your waterfall should be steep - following your curve at 0ms and rapidly dropping down so you should have very little showing at the 250ms or more point (which is a 1/4 of a second). This can show either how well your room is treat or if your sub is "flabby" and not controlled well. I'd love to see some waterfalls done for subs eqed to the same curve in the same room to compare the control. I saw somewhere at the REW forum where you could by the Galaxy 140 SPL custom calibrated with its own cal file for around $130. I'm seriously considering one. The Galaxy is known to have better response in the higher frequencies as well. If you already have an SPL meter, you can get a calibrated mic and pre-amp for around the same price as that galaxy - and is it a specific cal file for that actual Galaxy mic or a general one for all of the same model?

It is a cal file created for the specific meter he sends you. I think its 10 bucks cheaper if you want to just use the generic cal file.

The DVD or the HD-DVD? I did hear the HD-DVD was incredible. Didn't know there was an HD-DVD available but I've never had anything that would play HD-DVD. The DVD DTS tracks are quite good though and the bass is definately an order of magnitude better.

Great, if you are buying from someone including a specific cal file it's all good.

So the Dayton with the pre-amp will cost about the same as the 140, so if you have an SPL meter already that might be one to go for (it's easier to clip into a standard mic stand). If you can mount the CM140 somehow and do not have an SPL meter that seems a more economical approach.
