Hey guys, need s'more help once again . I got a price quote from somebody online about having a box built for 2 Fi Q 15's... I told him the dims I had to work with (40" deep, 19" high, 48" wide) and the tuning freq (32Hz) and he came out with the rest. Is this a good setup?

30" deep x 19" high x 28" wide

6.1 cu ft tuned to 32 hz w/88 sq in of port.

Thanks

n/m I am going to get a box designed thru Fisher Customs, but I'm wondering if I should go towards the lower end of the recommendation for the sub (2.8cuft) or the higher end (4cuft). What difference in sound will this make?

if you go larger tune lower like 28hz middle 30hz and the smaller 32hz personally i recommend the large low tuned box

I've heard a Fi Q 15 in 3.3 cu ft tuned to 33 htz and in 3.7 tuned to 33 htz and in 4.5 tuned to 32 htz.

I would personally recommend 3.5-4.0 tuned to 30-32 for rap. It gets so low and loud. The upper end really doesn't suffer too much from the extra space, and there is a real difference in the lows.

Ok thanks exactly what I needed to know
