Bob,

I paid a lot of $$ for Smaart, looks like REW V5 will do similar functions for free.

The ability to measure phase will make crossover alignment far more accurate than simple RTA programs.

I'd suggest trying several of the Panasonic capsules, recently tested several I put together about a decade ago and found some inconsistencies.

I have also bought and tried a number of different measurement programs. REW offers a lot of functionality and a great user interface for nothing. I use it a lot. There are some things that it will not do like swept distortion measurements, but hey it's free. Also it is updated regularily with new features incorporated. I can't believe John doesn't charge for it really.

Also look up the ARTA software suite. It is functionally free but I believe the license in order to save measurements is <$200.

I am glad to hear I inspired.
I wish I hadn't taken the time on my build as you have on yours. Looks top notch.

I also have used REW.
Cant afford other software. And I dont use it often. I normally use my DEQ2496 along with a Dayton EMM-6 to get a room response to adjust settings.

I do not have a good location for
outdoor testing. By backyard isn't empty and is sloped. But I will be in a 23K sq room in April so I will do my best to have time to do some test.

The boundary locations will affect the speaker response in singles or multiples, the change (if any) in the LF corner is what I am most interested in.

The outdoor response, even with a slope and some objects around would be more telling than a large room.

weight of only the wood, glue and paint is 47 lbs. have not weighed them with hardware mounted yet.

i personally have 90 hours into them. i had two boys help with glue and sanding. they each have 15 hours. so total construction time is 120 hours.
