Yes, 0.007 is 7ms which really isn’t all that bad. It’s bouncing back from the nearest surface - wall, floor, ceiling, etc  Move your trim pointer immediately before the bump and go from there.  Later on, you can reload that same driver file witho...

By placing the measurement microphone about six-inches directly in front of each driver to be measured should minimize its first reflection back to the microphone.  Of course the best, but usually not practical solution would be to place the speak... 
Building Resonance Free Subwoofers
Great job, Mike!  Your fine engineering, design, and workmanship inspires me to get out to my workshop start a new project.  But after seeing your workshop, I think that I need to do more than just a few updates first to it to say the the least.  ...

I don’t think the software is there as of this latest release. You may want to submit this as a "Suggest a New Feature" request. So far I’ve only submitted two request but I’m sure that I'll be adding more  soon. The following are the two reques...

The problem that I run into during the integration of a pair of stereo subwoofers using the Pre-8 is that all drivers’ relative sound levels, for both the main speakers and subs, are measured during the first step. Essentially, you place the measu...

Actually that sounds like it may be a great idea for measuring the subs and I'm going to be thinking about doing just that, but unfortunately that's not going to work, at least in my case, for a pair of 81-inch high 300lb (each) speakers.  Even a ...

Here a tip to help minimize aggravation when measuring speakers.   If it's going to take a bit of time to reposition blankets, wall coverings, sofa cushions, furniture, etc, between measuring your left and right speakers in step 1, consider LOGGI...

After some offline discussions with mijostyn about the difficulties in taking accurate measurements of dipolar speakers such a the Soundlabs that he has and the Apogees that I have, as well as any other dipolar speaker for that matter, I found tha...

Don’t give up too quickly. I know that it can be done. Yes, dipoles do radiate to the rear. Some less than others, but like you state, it is a major factor. The Pre-8 is my fourth DEQX since 2012 and I have great success not only with with this p...

mijostyn, Im glad that you pointed that out to me. You got me thinking. Even though I used lots of very sound absorbent padding on the floor, walls, etc, and I’m sure that the cloud processing uses software algorithms to minimize first reflection ...

Hi mijostyn, Alan replied back to an mail I sent may 30 on June 3. I figured that he must be swamped between further development and answering user questions. I questioned him because was perplexed at the final response curve that I was seeing. I ...

Hi Ted, Like me, you must be on the second wave.  Mine showed up a little less than a month ago and it been a tedious process.  I have been told by someone on the first beta wave that we're fortunate to be on the second wave since some of signifi... 
20 year old solid state technology.....
. . . 20 years ago, semiconductors could not handle as much power as the ones made today; more were needed for a given power output. Today these devices can handle more power so, at least on paper, less devices for the same power rating should yi...

Ketchup, that’s what Bruce was telling me when I let him know that I was running 18 psi. If you already have an ET-2 you may want to try upping the pressure before trying the 2.5. I don’t have a high pressure manifold and for that reason if I go m...

Frogman, I sure that removing each of the set screws is the best way. In my case, as clean as everything looked and the fact that spindle operates smoothly, I felt that pushing high pressure air through each capillary would sufficient. If you list...
