I bought a Power Acoustik Fubar 15" sub for my brother for Christmas, and I need to build a box. Power Acoustik's website has it listed as

2000 watts power handling
1000 Watts RMS
250 oz. magnet size
2.5Ħħ BASV voice coil
SPL 93 dB
Fs: 29.9 Hz
Vas: 4.45 cu.ft.
Qms: 6.7 ? Qes: 0.52 ? Qts: 0.483
Xmax: 0.52"
Sealed box: 2.25 cu. Ft.
Ported box: 3.4 cu.. Ft.
Tuning: 39 Hz
Port Size: 4Ħħ(dia)x10.5Ħħ(length)
# of ports:2
Mounting Depth: 8.0Ħħ


I sent them an email and they say the 3.4 cubes is meant to include the sub, and the ports. Well I want one port, and they can't tell me the displacement of the sub. I'm also using Unibox, the spreadsheet, and does anyone know what these figures mean? I punched in all the numbers given by power acoustik (which wasn't much), and now I get a whole bunch of output I don't understand, does anyone know which outputs are applicable to box volume and port size? Happy Holidays everyone
