CATB™
SE coaxial speakers feature Boston’s CATB™ (Contoured Asymmetrical Tweeter Baffle). The CATB™ offers to major advantages over a conventional tweeter post. First, its contoured baffle dramatically improves the off-axis response of the tweeter. Second, its asymmetrical shape makes the baffle acoustically invisible to the woofer, keeping the frequency response from the woofer flatter and smoother then conventional designs.



Type-S3 Tweeter
The SE component speakers utilize the Type-S3 soft dome tweeter. Its 3/4" size with neodymium motor structure, the tweeter is very compact and features Ferrofluid cooling for increased power handling. The dome material, a carbon injected polymer, offers a perfect blend of detail and strong output.

Customer Reviews

Reviewer: Tom Wright

To my suprise, the two SE35s I bought for my Jag didn't come with speaker covers.

Reviewer: Kurt

This is the second set of Boston 3 1/2" speakers I've owned. The first being from 1997-2001 in the dash of a 1989 Cavalier Z24. I now have a 2011 Jeep Patriot with the "Boston" system. I put Boston in quotes because they still use cheap dual cone speakers that are no where near the performance of some real coaxial and component speakers Boston actually sells. Anyway, the Patriot w/Boston system has 3 1/2" speakers in the fold out tailgate system, so I was more than happy to upgrade to real Boston 3 1/2" speakers, because my past experience was good, and I get to keep with the factory Boston theme. The speakers did the trick. Treble is much brighter. Not much more out of the woofer, as expected out of a 3 1/2", for all I know the factory amp may have high pass crossover settings, but I'm happy with the result. Can't hear them so much with the rear seat up, but with the fader 3-4 clicks back, I can hear the 3 1/2" over the rear 6x9" in the rear doors (next up to be replaced).
