Only if you're on serious drugs or a studiophile.

Hi Richard, I certainly can't promise (and don't) they will sound good to everyone in every room. That is an impossibility.
Some folks who like to see that kind of stuff and perhaps desire a much sharper, more "studio pan pot stereo construct precision" spatial presentation/sound, might prefer some form of treatment.
I don't because I attend lots of live classical, jazz and other types of non-amplified music and prefer that sort of "realistic" presentation. I also fully understand what folks like Floyd Toole found in controlled listening tests...and exactly how to apply that to my speakers. So that show after show, event after event (including local ones) sometimes in shoebox cramped, sparsely furnished hotel rooms, potential customers in droves still find the sound pleasing. Apparently the same for customers who have purchased. At least above the Schroeder frequency. For below, I prefer treating ears to added LF sources, which will spatially smooth the LF, adding a touch of EQ if necessary.
I do think the basic sealed/active design gives them a decent chance of achieving satisfactory bass in many rooms, even used as pure 2 ch only. YMMV.
