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

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

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.
