Bottom Line:
The following is for the speakers in their stock configuration:
Glorious High's, wonderful reproduction of women's voices, acoustic guitars and pianos. Treble instruments presented with wonderful soundstage and "air" around the instruments.
The bass is incoherent. Bass instruments sound flat, dull, and characterless. Certain mid-bass notes just seem to disappear. Very disappointing to listen to.
I tried several things to handle the bass deficiencies: room treatments, interconnects, cables, different amps, different rooms.
So bad was the bass stopped listening to Dark Side. I put the speakers in the closet for several years.
The solution to the bass: I modified the crossovers to make a 2-way system out of the mid-woofer and tweeter, and ran the subwoofers on a separate amp. I set the crossover point at 80hz, instead of the stock 120hz.
After this mod, the highs are even cleaner than before, and the bass deficiencies have been fixed. Bass instruments have individual character again, and the system can handle complicated bass material. Listening to organ music feels like there's a rush of air now. I love Dark Side again!
I believe that the crossover point of 120hz interacted poorly with the ports, and was complicated by phase shift. Literally one day after modifying the speakers, I found this article:

Känner igen beskrivningen av lågbasen i 2.5i, stor o maffig men lite odefinierbar...
Låter ju som att det kan vara värt ett försök att flytta ner filterfrekvensen mellan bas och mellanregister. Återkommer med erfarenheter och intryck när det är gjort.
