I am on a strict budget ($100 for driver) and already have a Bash 500 amp from PE. I am thinking of using the 18" sub from Mach 5 Audio. I live in Alaska and I haven't been able to find a large sonotube so I was thinking of a verticle rectangle around 19"x19"x44" with a 6" port 22" long.
Here are the T/S Parameters: MJ-18 - 4 Ohms
Fs = 28 Hz
Re = 3.2 Ohms
Qes = 0.34
Qms = 4.99
Qts = 0.31
Mms = 229 grams
Rms = 8.1 kg/s
Cms = 0.14 mm/N
VAS = 208.4 litres
Sd = 1029.2 cm2
Xmax = 12 mm
Cone Diameter = 36.20 cm
Power Handling: 600 Watts
SPL (2.83v/1m): 93.4 db
Recommended Box Sizes (this is from Mach 5 site):
Sealed: 80 litres (2.8 cu. ft.)
Ported: 128 litres (4.5 cu. ft.) 30Hz tuning
**EBS: 250 litres (8.8 cu. ft.) 18Hz tuning** (thinking of this one)
Any thoughts?
