i have a 15" truck box looking for a subwoofer that will fit a 7 1/2' mount depth and a airspace of no more than 1.25 cubic feet sealed box.

Was there any thing in it before? What amp was running it?

Hi jdavide,

Choose any driver size that fit your box and take a look at my simple calculations if you are considering a closed box:

What is your goal? Is accuracy more important than volume?

Also, what's your budget

I just want a good sub that will sound good in my box. $200 or less would b great.

Have a look at this Tang Band 8x12 driver

In a 1.5 ft^3 ported box with 250W, it will get you 112db (before the addition of cabin gain) with a F3 around 33Hz. The port required would be 4" diameter by 21.5 inches long

The driver is about $80 so that should leave you enough for the amp out of your $200

Sorry bout that I didn't say what size sub it needs to b a 15" subwoofer

For the driver I mentioned it will outperform a 15" in that size box, at least within your $200 budget, just make a filler plate for the 15" opening.

In fact the only way any 15" will given you decent results in that size is if willing to drop $1k+ on a high end driver and amp.
