About to get started on getting a box for a fi bl 15. I have the space so was thinking about 4-5 cubes as one fi page suggests 2.8-4 and another 2.8-5? want to hit lows and still have it get a little loud and don't really know 100 percent about tuning but was thinking 33 hz ? Any suggestions I appreciate or input...power is a saz 1500d v3...thanks for your time

I'd say 2.8-4 closer but closer to 4,I built mine at 5 and it hits the low low frequencies nicely but it was flat when it played the higher of low frequencies, know I have to build a smaller enclosure.

What do you drive? What kind of music do you listen to?

I drive a 2001 grand cherokee limited, listen mostly to rap/hip hop as I like the bass of course. Or music like bass nectar, and stuff like that that brings out nice bass lines

 

5 cubes net tuned to 32hz and ample amount of port area, BL's have alot of motor force.
