    Quick question - ported box.

    Hi guys. I'll be building a ported box for 2 audiobahn 10" this weekend, and I have a question. The Vas for this particular sub is .85 cuft, displacement is .10, which gives .95cuft per chamber. Since I'm porting this box, should I increase the cuft per chamber? Would appreciate some numbers . Also, this box will be for SPL, tuned at 40-45hz. Round or Square ports, which would be better?

    thanks,

    Rick

    the bigger the box the better for ported boxes.

    vas is not a number you want to be looking at, unless you know what it means, and how to implement it alongside the other T/S parameters...
    which audiobahn drivers are you talking about..
    give me model numbers and year.

    try 1.6 cubes before the drivers displacement, but after the port displacement... tune to 33 hz, and use a common chamber...

    Just to be clear, 1.6 cuft total volume, or per sub? 33hz would be right for an SPL box?
    Seems I was way off, but thats why we seek advice from those that know . One last thing, just out of pure curiosity, why use a common chamber?

    per sub...
    that's a little low for a pure SPL box, but a good spot to use for a daily driver to get them loud.
    use a common chamber because it's the only way to make sure you ahve them both tuned to teh same spot...

    hmmm now that you mention it, a slot port would be easier with a common chamber. I'll look into that. If it's within my ability, I'll go for it. Thanks again.

    Just an update..... Box is built, ports are tuned, subs installed, and to be honest, I'm impressed. These are low end audiobahns, and the general consensus is they **** for SQ, but they're not half bad. On the SPL side of things, they are LOUD, VERY LOUD. I didn't expect this, but hey, it's a nice surprise. I'm really VERY picky about my mids/highs, but I'm fairly easy to please on the low end.

    I'm going to credit the recommendations from Wonderbread (and the nice gain from my jeep cherokee ) for this awesome success. Thank you very much, Wonderbread
