    Wink 2225, 2235 mass control ring

    hi,
    this is my first post. does any one out there know if the 2225h/j woofer use the mass control ring? the jbl lit i have makes a big deal about it in some of their lit, in others , they don't mention it.
    i have seen this in the 2235. when they do mention it, they state that it offers better control at about 1k. what advantage/disadvantage is there?
    in my system (4671) the 2225 (8 ohms) goes up to 800hz where it is crossed over to the 2425 using a 3110a crossover. the 4430 (2235) goes up to appx. 1k, then to the 2426. in my system the crossover is seamless. when i heard the 4430 there was a boom around the crossover frequency.
    any one out there noticed this?

    thanks

    2225 no ring. 2235 (single in 4430) is same as 2234 (two in 4435) but uses a mass ring to lower resonance frequency and extend bottom end response at expense of slight sensitivity loss and lower upper range limit.
