Crossover point of 5.25” vs 6.5” in two way bookshelf

I am not sure I agree with OP that the specs offered by SF seem backwards. A larger diameter woofer should beam at lower frequencies but also allow for higher power inputs. The tweeter should Ideally cross lower to preserve wide dispersion before breakup or beaming in the woofer occurs, but that stresses its power handling.  If SF is using the same tweeter then the higher crossover frequency is probably intended to reduce strain on it at the higher power levels expected from the larger woofer and enclosure.  What this tells me is the 5.25” model is probably a better option if you don’t need more volume or bandwidth than it can comfortably accommodate. 

Just two things.  One, there’s lots of excellent 2 way speakers with 6.5" class mid-woofers that sound really good.  Second, remember that the tradeoff for a low cross point is also reduced dynamic range and higher distortion.  It is a "compromise" no matter how you do it, but so is every single speaker out there.

Exactly right.....no free lunch.  Speaker design is twisted game of whack-a-mole.

Well I’m not sure what the actual crossover point is (lol)… but I picked up the Smaller Sonetto I’s and they sound wonderful paired with the SVS micro 3000 and Rotel RA-1572mkii. My room is not huge and I don’t listen at rock concert levels so the smaller speakers are more than enough I think. 

As the saying goes, "the proof of the pudding is in the eating."
