Right, for my sub, its provided with different boz specifications depending on what you want out of the sub. I'm reverse mounting the sub and have taken Sub Displacement into consideration. All of the following are to scale
First of all, my empty boot:
Sealed is obviously the smallest, taking up between 0.5 and 1.5 CuFt, so i chose 1CuFt just for and idea on size:
The next set is called Everyday Bass Performer and gives figures of:
Air Space = 2.25 CuFt
Port Size = 4 x 8.25 Inches
Port Vel = 18.21 %
-3dB = 30 Hz
Tune Freq = 36 Hz
Port Disp = 0.055 CuFt
Total Vol = 2.305 CuFt
The last set is called Ultimate SPL Bass Box and gives figures of:
Air Space = 3.15 CuFt
Port Size = (2) 4 x 13 Inches
Port Vel = 9.19 %
-3dB = 28 Hz
Tune Freq = 35 Hz
Port Disp = 0.179 CuFt
Total Vol = 3.329 CuFt
Originally i was gonna just build the Utimate SPL Box, but having done this and looking at the actual size of it, i'm not sure if its a good idea or not
I definately want the most out of my sub, but i dont want it to sound stupid and not responsive when playing trance etc
