Perhaps the JBL 530 or the Ascend Acoustic Sierra and Sierra 2 bookshelf speakers would be more right for you, as they do reach under 50 Hz.
My own personal (and significantly smaller) experiences with HiFi audio (and specifically EMP Tek brand) mimic dsrussell's...
My Polk Monitor 70 Series II floorstanders are 42" tall, and have four 6.5" powered drivers (with a low-pass filter on the bottom two to focus solely on bass), and when audyssey runs, it determines that they are "full range" and I believe tried to set my crossover up to be at 40 Hz. Comparing their performance in 2.0 channel, bass performance is SIGNIFICANTLY improved by crossing over into my SVS PB-1000 at 80 Hz.
None of this gear is anything close to "top of the line"... but just to speak to my own personal experiences with floorstanding towers, they may not *need* a subwoofer as badly as bookshelves do, but they will still benefit from it, and in my opinion, the improvement is not insignificant.
Also, I just recently became the proud owner of a pair of R5Bi's, and for the time being, they happen to be paired with a VERY low-budget Polk htib 8" "subwoofer". At least at low volumes, the R5Bi's benefit substantially by that 8" woofer. Now, as I turn the volume up louder and louder and louder, the R5Bi's quickly start to shout down this low-budget low-end subwoofer I currently have them mated with...
Anyway, just wanted to share my own experiences on:
- Tower speakers benefiting from a proper subwoofer
- R5Bi's benefiting from even a small budget sub.
Hope this helps.
