This kind of sums it up. A comment early in the review
The woofers are pretty weak sauce. While they do play clean they just can't put the SPL's in the bottom octaves that I need from a fullrange speaker. Port has a foam insert to calm it down and sounds good with no chuffing despite the little woofers epic fapping at volume
This is the reason the ADS L1590/2 are gone. Sure they were a good speaker but my tube amps didn't like driving the dual woofers and the bass was flabby. I can live with the DQ-10/Magnepan/Time Window sound and not have to deal with flabby bass when enjoying the tube amps.
For those of us who have no experience in how circuits actually work (building a Dynaco kit 45 years ago does not count) and who know only what their ears, a few reviews that can be triangulated to try to cut down on biases, and a few technical articles tell us - Joe can be invaluable. Fortunately, you guys go working on this stuff and all I have to do most of the time is just listen and I'll pick up something each thread. But every now and then I just want a little guidance on the basic principles which means I gotta ask.
