    Is this sealed box too big?

    I currently have a Boston g310-4 subwoofer. The recommended min/max sealed box size for this sub is .50 cu ft. I have the opportunity to buy a sealed box that is custom fit to my car, but it is 1.16 cu ft. Since this box is almost double the recommended size, will it degrade the sound quality? Thanks

    That box fits it ported though. I see you're in OKC. Hit up pro-rabbit @ DC Creations. He's a box designer on here, a moderator for the site and has a business in OKC. He'd probably put in an aeroport or tell you how to do it. You'd get better output of the G3 ported anyway.

    I agree with DoesDad that would be easiest. You could always try the sub in the sealed box and see how it sounds some subs sound really good in a larger sealed box.

    In the oversized box - you will reach the mechanical limitations of the sub much quicker (since there isn't as much of a 'spring' behind the woofer).
    How much power you're putting to the woofer will greatly influence this - but long story short, I'd stay within the recommended specs.

    Put 2 woofers in that large box, port it, or have a proper size enclosure built.

    You could buy the enclosure and add some internal bracing to strengthen it and eat up some space to get you closer to where you need to be. A few 2 x 4's would be inexpensive and eat up space quick.

    unless you are getting some crazy stupid deal (free), I wouldnt buy a box so far out of spec. I cant imagine that any shop coulnt whip up a 0.50 sealed box cheap. I have had a few sealed boxes that were larger that spec and it helped the low end, but none were that far off.

    Re: Is this sealed box too big?

    figure in sub displacement too when you are making the right size box



    Head Unit: Pioneer avh-4300dvd,
    Front Stage: Ascendant Audio 6.75", Massive Audio 28mm tweeters
    Rear Fill: Massive Audio CK6-3 6x9 Woofers
    Amps: PPI Phantom P900.4, Sundown Audio SAZ-2500D
    Sub: RE Audio XXX 12" 2.25^3 Tuned to 32

    They sell Kicker at Wal-Mart now. That's saying a lot..
