    This should be interesting.

    I picked up a couple of ID subs from a guy at work. He claims they are SPL's they are 15'' subs with a double stacked motor and a stamped basket. The claim i dont trust is that the were built for 2200rms a coil, i saw quad coils which were even more rare and then the dvc most said would handle 1100rms since what tiny amount of info i could find suggested the use of the IDQ specs for enclosure design ive chosen a bandpass. this will be a blow through in my 06 nissan frontier, I think im settled on 4 sealed 8 ported, tuned to 45 with 2 10'' sonotube ports, i might be able to get away with 8's if i can do my own flares.

    Any serious suggestions are welcome. i did not list an amp because i dont know what these things will handle but i have an AP30001d sitting around.

    This should be interesting.-band-pass-me.jpg

    and go. hows this look? thinkin some 3/4 plexi in the access panel and all thread for bracing, what size all thread is suggested i was thinking 1/2" would be plenty if i use neoprene and regular fender washers.

    scratched the round ports as then i have to cut multiple holes and cant find 10" pvc for a reasonable price

    Not many with technical knowledge anymore. I don't know much about bandpass enclosures man, but I say just build it and post a build log.

    Re: This should be interesting.

    I need to know if this looks like a decent design, the bracing i plan to do is all thread and mdf what size all thread should be big enough? Does this look like it will work well, or should i try to change the design entirely?

    If they really are ID SPLs (very rare subs) then yes they're similar to an IDQ. They're not exactly a 4th order friendly sub from what I can see of the TS parameters. And if you put that AP3k on it with all kinds of distorted power they'll go up in smoke.

    Re: This should be interesting.

    where are you getting specs from? the ones i have seen from ID's site for the idq suggest it wouldnt be a bad sealed sub, meaning it should do well in a 4th order.

    You (generally) want a sub with high Qts, low Fs, and higher Vas.

    The qts seems pretty low, but you might still have good results

    Re: This should be interesting.

    putting the pair in just under 4 cubes sealed after bracing and adding poly-fill to that with the motors facing out to the ported chamber that will be right around 8 after its port bracing and subs. the access panel is kinda funky but was thinking 36x12 3/4 plexi with a 3/4 inch piece of mdf as a mounting surface on either side. that would give me some room to replace subs if need be.

    the ap3k has been doing its thing in my truck for a few yrs, about 4 if that matters. I have only used it at 4 ohms, but at that ive seen all the claims and believe it was close to the 2k claims. i wont say its high sq but it does a decent job and was cheaper than anything else when i got it.
