DD 9515 box question

[8thGenSI 10+ year member]

Ok, I know the 9515 is not the ideal sq sub but I am going to be running it off of 2k watts daily and wanted to ask what I should tune the box to? I want to try to get it to sound half way decent. I figured I would run about 4 cubes but what would be a good freq to tune the box at?

daily 34-39. I hear good things about 39. Mines 34 but definately rapes all lows

I've done them in 4-4 1/2 cubes at 35 & 38Hz. Both set ups sounded good for daily and got loud.

I would tune at 35Hz for a little better SQ as it seems to give a little flatter response...
