Tuning for 2 10in BLs

[aherzing 0]

Im currently using the RE Enclosure calculator (http://www.reaudio.com/speaker_box/LPort_Box_Calc.html) and after putting in the dimensions I can fit in my trunk and Im playing around with port size and what not and I was curious, the "tech" section on the Fi site says the recommended tuning is 33hz, I can only get my box to fit if I tune it around 34hz, is this an issue? would it be better to be lower than ideal if you cant get the ideal 33hz like 32hz instead... Or am I not even gonna notice? Also, again refering to the "tech" section, for the 10s it recommends 15 square inches of vent per cubic foot of air space, is it a major issue if I can only work around 12 square inches?

Specs for the box for two 10in Fi Bls

Air space after woofer displacement: 2.475 Cubic Ft

Square Port Area: 31.25

Tuned Frequency: 33.79hz

Good enough?

Also side question, is there any disadvantage to having it built with the universal option as opposed to not?

It depends on your listening preferences but it wont that big of a difference between 34hz and 32hz, since you dont have either one built to compare you wont notice. If thats all you can fit then go for it or go smaller if the tuning is to high for you. That tuning should be fine since it says on the tech page that BL 10"s can be tuned from 30-37hz. Hope this helps.
