Nice work! The FR looks good enough to enjoy already. You'll probably work on the low end, but it's not an emergency.

Cool design, too.

Nice design! It's amazing what a miniDSP can do. Before dsp, all this would have required super expertise in designing a XO and EQ active circuit a la Linkwitz Phoenix. Looks very cool, I bet it sounds great.

The response looked good. It has to sound good.

Maybe so kind of full length grill would increase WAF. It would be a shame to abandon what looks like a winner.

Nice effort so far. And you deserve to enjoy it.
But dipole truth is in the polars . I look forward to see the shortcomings - if any.

Lovely design.

What colour are you going to paint them ?

Well Linkwitz helped a lot with his documentation on how to do active correction for dipole. Still, it is really astonishing what you can do in about an hours worth of measuring and tweaking!

Yes, It would be nice if I could make them. Do you know any free tools that work with OSX? REW doesn't seem to support polar plots. I will do some off axis measurements later this week. That should also give you an idea.

Well, this one won't get any paint, since it's only a test model. I'm still not sure about the final version. I'm not sure if I want to use MDF and give it a paint job, or make it out of bamboo, and just clear-coat it. I have some time still... the design is not yet final anyway.

No need to show polar diagrams. I meant to just ask for off-axis measurements up to 90° .
If you can export your impulse response measurements as .wav files, I could turn them into polar plots or sonograms for you using ARTA.

A thoughtful and innovative design, well executed to this point. I find the form factor very appealing.

Congratulations, I think you have a real winner on your hands! I look forward to your continuing work on it.

I like this!

I'm interested in horizontal off-axis measurements too! Just do the various measurements and mak an Overlay of them! And what xo frequencies you use, what topology?

I think it should be easy to eq the woofer even more (flat to 30-35?) , but perhaps at the expense of overall "efficiency" Be careful for not boosting low end, because without high-pass it leads to digital clipping in minidsp.
