Can anyone provide feedback on how they compare to the 3677s?
I can't quote on the CD but I can on the Woofers and I currently have 2 QSC bass cabinets (basically the exact same internal volume and tuning frequency as the 3252 cabinet) with dual JBL M115 drivers. This is The cheaper driver of the bunch and also used in JBLs cheaper PA speakers.
They both hit hard mid bass wise but the JBL 2035 in the 3677 sounds better and has a tad more slam, the second woofer in the 3252 only helps get the sensitivity up and isn't really needed at all in our rooms. You're also using these speakers well into the vocal range with the high crossover points in both speakers so a quality driver is a huge plus.
Google around about the 2035 and you'll see it's used in JBLs very high end cinema line as is the 2226 and is regarded by those who've used them to be a very nice speaker and used in many high end DIY builds like the 4pi. Is it as good as the 2226? for our use..I'd say it's pretty darn close. You won't find the M115 in anything but the budget speakers (JRX for ex) and in the DIY world it's kinda frowned upon.
If you search the 4pi and my name, you'll see Wayne also used to use the CD driver too. He later went with the B&C because it was cheaper, just as smooth and higher response doesn't hurt.
I'm not meaning to dog on any speaker... I'm using the m115 drivers (crossed at 500hz though not 1300hz). They both have great midbass but I would put the 3677 a good bit above in this comparison, as for frequency response I feel it's a non factor. The fact they can both be had for about the same $$ and the 3677 has one less driver should tell you something about its components.
IMO if you want to upgrade above the 3677 (bass driver wise) you're looking at the 4722N/3722N with the dual 2226 drivers. But I would bet the 3677 (in our rooms) would be able to give even those a run for their money as in that scenario it would be 1 high end driver against 2 high end drivers and neither speaker would be straining at all. Of course overall I'd expect the 4722n to come out on top due to the much larger waveguide and lower crossover point.
It's also harder to tune and properly place an acoustically taller speaker to sound good to multiple rows. Especially with a high crossover , you really need all the drivers to image and not be blocked with multiple rows. Some 4722s have been lowered to bring the mutiple rows all more on axis and not need lots of down tilt but the screen frame blocks the bottom woofer slightly.. not as big a deal when you cross at 750hz .. but when you cross at 1300 hz it's a bad thing.
