sonotube almost done (1 Viewer)

[David_Lew]

my sonotube, aka ghetto tube, is near completion.
my cirle cutting skills need help, but it's my first time messing with wood, so close enough. My sonotube from whitecap
is 24.5" wide, .25" thick. Overall length with legs is 25.5".
It's a mini monster having my psw450 next to it. Inside is a Titanic 12" MKII, 1 4" x 17" port, term cup, polyfil.
I just need to dress it up! I have it inside to play with for now, it's nice, but I'm not feeling the bass enough .
I have the PE250 amp powering it, I need to build a little box for it like Ron-P.

What are the specs?.....

net volume -
tuning frequency -
t.s. parameters (maybe others are familar with the Titanic) -

From PE's website:
Thiele-Small Parameters * Power handling: 350 watts RMS/ 490 watts max. * Voice coil diameter: 2" * Voice coil inductance: 1.91 mH * Nominal impedance: 4 ohms * DC resistance: 3.03 ohms * Frequency response: 22-500 Hz * Magnet weight: 108 oz. * Fs: 22.18 Hz * SPL: 91.3 dB 2.83V/1m * Vas: 4.46 cu. ft. * Qms: 9.56 * Qes: .43 * Qts: .41 * Xmax: 18.9 mm * Sd: 77.7 sq.in. * Net weight: 20 lbs. * Dimensions: A: 12-1/2", B: 11-1/8", C: 6-1/2", D: 6-1/2"
I'm estimating ~136l of volume, including sub & port.
I'm not sure what it's tuned at. I have no program to run the specs. Internally 24.25", height minus endcaps, 19". 4" x 17" port & size of sub if anyone wants to take a guess what it's ported at. Thanks
