Re: WinIsd help!
Depending on the driver, that might be about right. Bandpass enclosures are not small. Factor in the high Vas for the W0 series drivers and they end up not well suited for bandpass use especially in a tight location (like the cab of a reg cap truck?). I just ran the numbers on those through a spreadsheet off DIY and those numbers you gave are the optimum for those subs. Yes, that is a huge box, and yes, that is what those dirvers need for a 4th order bandpass.
If you are dead set on using those drivers (since you already have them) your best bet would be to go with a sealed box for use in the back of a reg cab. If, however you want a bandpass, you will need to go with different subs.
