    I'll be getting some more subs today.. 3 JL W610's in a box.. I already have a JL W315D4...

    I'd like to set something up with all 4 subs, but I've heard from others a few theories, such as different sized subs of different ratings don't sound right together, etc.

    Can anyone correct me or agree? I figured if they are setup right on different amps or something, it shouldn't be an issue.

    I would not reccomend using more than one specific size or type of subwoofer in an installation.

    bad idea.

    what 042801 says is pretty much law.

    A local shop owner with a "story" told me he hit 160db with 2 JLW7 10's and a 12. I wanted to say what the fuck was the point of that :dunno:
    Hooking up 3 10's and a 15 is a really bad idea :rofl:

    Don't do it your speakers will be out of phase and it will sound like crap. stick with 1 size subs in 2 enclosure.. 2 boxes is dumb and would be horrible.

    It can be done if you do it right. Tune each type to a different freq, and have differenct frequencies playing to each. i.e. have the 12" play from 20hz-40hz, and the 10's playing from 40hz-70hz. But you'll need some pretty good amps/crossovers for this.

    Check out ////Alpines demo car before you say not to use different size subs. :) I believe they had everything from 8"-15".

    :wiggle: I want that car. :wiggle:

    lowfat is right, if you are going to do more than one sized sub, that is the way to do it. As to why anyone would bother is beyond me. :dunno:

    The 12" woofers would be able to cover the entire 20hz to 200+hz spectrum just fine.

    I can already tell you that their is no real practical purpose to that without even seeing the car.

    Now, if it had 8" woofers up front, 15" woofers in the back, thats one thing. But unless they are stupid, they would cross over each woofer to cover a different frequency range.

    I'm sure that is what they did regarding crossing over each sub.

    They DID have the 8 inch up front in the lower kick, and maybe it was just 8", and 12" or 15". They DID have the smaller drivers up front.

    Everything is completely fiberglassed in. Now I"ll admit... most of that car is for looks only. For instance... they have the MRDM100, MRDM500, and the MRVF540 arranged in the rear of the vehicle just so it looks good... kinda like an upsidedown triangle with the lengths of the amps.

    But at the same time... I would think that having an 8 inch driver in the front of the car would give one kick-ass stage. :cool:

    I only wish I had the cash... :hs:

    Yup, and that is a good setup too. You take some of the burden off the front midranges from having to play so low. You can cross your subwoofers over even lower, which makes localization that much harder.

    I just don't get why people will have say a 10" and a 15" woofer in the trunk of their car both playing the same frequencies. I mean, you COULD get it to sound fine, and it would be louder than a single 10" or 15" woofer, but seriously, why bother?

    just a wild thought, how about 2-12" in trunk and 2-8" in cabin? :dunno:
