It's designed for the smaller theaters, and that's how it's advertised, that doesn't mean it's sound within its limits is inferior. It can't handle as much power and isn't quite as sensitive as the others mentioned, It basically has the same cd as the 3622/3722 with a smaller waveguide.
The 2035 woofer is slightly more expensive (jbl direct) than the woofers used in the 3622/3722 and even a few $ more than the woofer used in the 4722n (265h-2) And a few dollars more than the popular 2226, however that's probably a supply and demand thing as I thing the voice coil on the 2226 is better.
The 2035 is used in some of the higher end cinema lines too. Here they are in a $3000 dollar cinema speaker.
Looks a lot like some more MK had, not sure what woofer those had.
As far as drivers go, the 3622/3722 actually has the budget 15 (m115-8) not the 3677. Definitely something to consider. As as far as the woofers go the 3677 in no way has the budget or inferior woofer based on driver price and what other higher end cinema speakers they're used in, and may be the best woofer out of the speakers mentioned as none mentioned have the 2226h. they probably all have their pros and cons.
By driver comparison I'd say it's as low end as the 3722 is within its limits and intended purpose, small theaters, where the 3722 is the budget speaker for larger theaters, and the I've owned it, and it was by far the most impressive speaker I've ever owned.
Just kinda putting my thought out on the forum as I'm still torn between which ones to get, reorder 3677, or go for something that may or may not be a nnoticeable upgrade. I'm just not sure the 3722 will actually be worthy upgrade sitting 15-18 feet away. Because I can't hear them all I can do is compare the drivers.
