Is DEQX a game changer?

Congratulations, Bruce! Glad to hear that the time and effort you've put into this assessment has paid off.

Best,

For those thinking about measuring outside, for practical reasons I don't do it. The last DEQX calibration that I was involved was with a pair Apogee Full Range and at 300 pounds each they ain't going anywhere! Measuring outside lengthens the time it takes for the calibration microphone to hear the first reflection. Longer the time until the first reflection, the lower in frequency your calibration will be accurate. Recently, after talking with Nyal Mellor of Acoustic Frontiers, I normally don't try to correct anything below 500 or 600HZ anymore. I seem to get better results now rather than trying to correct all the way down to 250 to 300 Hz or so which is usually where the first reflection places its limit on lower-end calibration when measured indoors.

Normally when I do a DEQX calibration indoors, I move the each speaker (if movable) one at a time to the center of the room and perform a measurement then move it back. I also toss some blankets of the floor between the microphone and the speaker to be measured, then perform the measurement. The first reflection usually comes from the floor or ceiling.

What I saying is that by not measuring the speakers outdoors is by no means a deal breaker. You can get great result measuring indoors. Just use the Earthworks M23 or M30 calibration mic. If you have large speakers with large ribbon drivers or large array like Apogees, you will probably find that you will get the best results if you measure the speakers anywhere from 5- to 7-feet back rather than the recommended 3-feet.

Glad to hear you had a successful demo Bif. I am happy to help if you need any advice once you receive your unit. Did you go for the DEQX Mate?

The DEQX home demo was completed last night. I am buying the DEQX.

Not being inclined to the use of vivid hyperbole, I do not think the DEQX is transformational. But I do think the improvements are considerable and significant enough for me to spring to buy the DEQX.

awesome!
I'm happy to read that you now recognize the importance of time coherence to music playback. :-)
it IS very significant.
The time-coherent speaker manuf weren't barking up the wrong tree - no sir, they were not...
So, anyway you can make your speaker time-coherent will work to significantly improve your listening pleasure: apply a Band-Aid like DEQX or buy a time-coherent speaker from the get go.

Bruce, maybe you'll be transformed in time to come. I'll poll you in about 6 months & request you to pull out the DEQX from your system & give me your opinion. I'm wagering that you won't be able to listen to your system ever again without DEQX.... ;-)
That's what happened to me - once you get use to a time-coherent speaker system there is NO going back even for a few seconds....

As others have already written, I too await your report after you've collected your thoughts. Thanks.
