Subs are SPLUSA - Subwoofers - SP3-15 (http://www.splusa.net/spl2011/subs-SP3-15.html)

My question, is a port of this size diameter accurate?

If not could I get suggestions.

Box will be around 8ft^3 before displacement. Subs up port up.

Thanks

I've tried numerous online calcs and abosolutely no values are similar.

At diyaudioandvideo

Vas = 5.451 ft3
fs = 23.4 Hz
Qts = 0.745
D = 14 in

Dimensions
Vb = 41.27 ft3 = 1168.6 lts
= L x W x H
f3 = 9.6 Hz
fb = 35 Hz
Dv = 6 in = 15 cm
Lv = -3.3 in = -8.31 cm

This can not be right, can anyone guide me as to what I must be doing wrong!

Again its going to be 2 15"s my max space is 55"W 41" H 34" D I would like a tune of around 34Hz using aero port thanks!
