    JBL 3678 or 4638/2352/2447

    I was going to buy 3xJBL 3678 for my hometheater today... but ended up with two LCR speaker systems

    I bought 3xJBL 3678 (2226 and 2425) and another bigger system that consist of 4638 boxes (2x2035) with 2447/2352 horns.

    I'm going to hook up the 3678 later tonight, but the other system needs active x-over so it's not that easy to test right now.

    What system do you think will be best suited for hometheater (and of course some music)? I think maybe the bigger system will be best, but I have not found too many users of 2447/2352... so I really don't know it it's any good.

    Sounds good to me.
    Those are the horns and drivers I want to upgrade to, using my Be diaphragms and I've heard that the 2352 sounds really nice. I'm using 2385ss w/2445's right now.

    I would also belive that 2447/2352 with Be diaphragms would sound pretty nice so maybe that's what I will be amining for!For now I've hooked up the 3678 in my HT, they look quite small next to the 4645 subwoofers (there will be 4x4645, probably 2 on top of the others)The bigger setup is still in storage in the garage:A third alternative is a three way EAW CB523 that I haven't bought (yet), I wonder how they compare to the JBL:

    Looks great! Reminds me very much of my own system (2x4645C and LCRs consisting of 2226 + 4722-HF ScreenArray horn).

    What are you using for calibrating/powering the speakers?

    I currently use three 4622n's for HT, which is the 4639 (2 x 2035) and 2430/2384 combo. BUT, I also have the 3 of the 2352/2447 laying around.
    Now I wish I had tried them with the 4639's....

    I haven't got the time to try the bigger system very much yet, I've only hooked it up to test that they work... I like the 3678 very much but from the litle test I belive the bigger system have more potential so I'm not sure what to do yet. The disadvantge with the bigger system is the need for active x-over and more amps but maybe it's worth it I've several amps so I'm not sure what I'm going to use, but probably Parasound NC5125 or Emotiva XPA-5 if i'm useing 3678. If I'm sticking with the bigger speakers I will probably use my Crown SR2 for the L/R woofers and Parasound or Emotiva for the rest.... or maybe I will sell them all and buy Crown amps with builtin DSP/XO.

    Present I'm also only useing two of the 4645 woofers but I'm going to use 4 of them!
