    Thoughts on an enclosure for the home - LOW Fb

    I've had this spare Lanzar Opti1232d here doing nothing for a few months now. Always wanted to build a nice home sub but never had an amp for it. Recently picked up a 500w amp cheap (bash 500s) so I've designed a box.

    This sub has a Fs of 29. Basic specs and manual are here if anyone's interested.
    The box that was recommended on a HT forum is 4cf tuned to 21hz w/20 sq in of port.
    My compromise is 3.4 @ 23 w/24 sq in.

    Anybody have experience taking a car sub that's usually tuned in the 30's and going this low with it?
    It's only going to be driven with <1/2 rated power, and rarely at full volume.

    Considering this will be replacing a pre-fab 5.25" jensen at 30w rms I'm expecting exponential improvements.

    Thoughts? Suggestions?
    Relaistic expectations?

    It doesn't take a lot of power or a large sub to get plenty of output in a HT environment.

    try and plot it in WINISD if possible, and see what you get

    You should be happy



    HU: Pioneer 880-prs
    Mid/High Amp: MB Quart DSC4125
    Front Stage: PG mids/Vifa tweets running active
    Sub Amp: DD Z1
    Sub: 10" Mach 5 SPL/Hybrid 1.25ft^3 @ 38hz
    DC Power Alt

    Big, low-tuned boxes are the way to go for an EBS alignment. Plot it in winISD so you can really see how it'll respond in the box you're wanting to do.
