    RE XXX 15: sound quality build; ported or sealed

    I am leaning towards sealed; I have a slot ported box that would be 3.25 cubes if I sealed the port and probably 3.00 or a little less with the port open.

    It is a generic box and I'm not sure the tuning, but the port does not bend so I assume it is tuned relatively high due to the short length.

    I guess the big question is, will it be close to reaching its full potential in the 3.25 sealed box or could I get a lot better sound quality form building a bigger box, which I really don't want to do. I realize the tuning is gonna be too high and box too small to run it ported.

    So, will the sound quality be much better in say a 5 cube sealed box, or can I get great sound quality out of a larger ported box tuned to say 28hz

    Like Jeff said above. Also get a proper ported box built for it.

    First is first, what do you consider "sound quality"?

    Build a ported box properly for it. Don't just throw it in a prefabbed. I had an 03 Quad XXX 12" that got low.

    And 5 cubes is way to big for that sub. Mine was 5^3 tuned to 32, should have been closer to 3^3.



    Current set up: Island bombed out 92 mazda 626. Stock rust bucket

    66 Pontiac GTO, modified stock radio, Crossfire CFA 302, Kicker KS6.2's in the front kicks, Crossfire CFA 452 for the 6x9's I need.

    what year XXX is this.. If it's 2006 or newer then ported really INS'T a good option. That sub has 40mm+ of xmax and not enough motor to back it up in a ported environment. Your wasting most of the unique capablility of the driver by porting it. If it's a new XXX build the biggest box you can reasonably fit and power to it. If it's a old one, then 3.5-4 cubes at 28-34hz is usually about right.

    Re: RE XXX 15: sound quality build; ported or sealed

    I want to be able to hit the lowest lows up to the crossover cutoff at roughly the same output; not "peaky". It will be powered by a AP3000D at 4ohm (1800-2000 watts)
    in a small BMW 325ci trunk

    And yes, new XXX

    I see what you are saying, but that sub won't use that xmax in any box. And a lot of it has to do with the split coil not handling power as well as it should to even achieve those levels of excursion.

    OP what kind of music do you want to bump to?

    I totally get what you were saying though, but RE isn't what it used to be. Seems destined for any large company to sell out after so much time and success.

    It's all about the bottom line. I get that. It's still a shame though. Kind of like Orion, RF, etc... Companies like Sundown get big enough and they'll do the same thing. I think at some point it's almost unavoidable.
