Did you check out this post?
Thomas & Stereo posted this interview with Harley Lovegrove and much of the discussion is about speaker measurements. Harley provides numerous insights on speaker design and discusses the pros and cons of a implementing a flat frequency response. I enjoyed the discussion and wanted to share.

From personal experience, I can say that the measurements of the MA drivers are consistent with my experience. It's a pretty cool driver for what it is. It has VERY limited use cases that make sense IMO. I love mine. I absolutely love them. They do some things really really well. Similarly they do some things very poorly. I have to listen to these off-axis and the sweet spot is quite narrow. Not narrow like you can't move your head, but if the speakers are about 6' apart and you're about 6' away from them then you're locked inside your chair. The treble tips up on axis and then rolls off off-axis.
Box design greatly influences bass response. In my experience somewhere around 100hz in a sealed box the bass starts to roll off. You can design a box to get it to dig deeper, but I choose instead to crossover to a pair of subwoofers at around 150hz. With a crossover that high, I found that bass could be localized which limits subwoofer placement.
So people that complain about single driver speakers... I get it. You're not wrong. There are better choices for most scenarios. If you can minimize the inherent flaws or downsides then there's actually a lot of upside. I probably wouldn't use these in a home theater. I wouldn't put them in my living room. I think they'd probably make solid desktop monitors. Personally, I have a little listening room with a single chair, and I like these speakers in this room, better than anything else I've tried.
