Hi guys, nice forum 
I'm planning on building a subwoofer for my home theater (surround sound only). In my country I can get the Ascendant Audio chaos 15" in a relatively good price but only in the dual 2ohms version. To order the SDX15 will cost about 50% more.
I have a crown CSL800 amp that outputs 640W into 4 ohms. My room is 13ft. X 15.5ft.
I was thinking of building a ported enclosure of 200 liters tuned to 20Hz for the chaos 15 OR and if the added expense really justifies it, a 225 liters enclosure tuned to 18Hz for the SDX15.
The chaos 15's t/s parameters are:
Re: 1.5 Ω
Fs: 27.1 Hz
Qms: 6.62
Qes: 0.47
Qts: 0.43
Mms: 260 g
Sd: 810 cm^2
Vas: 121.8 l
SPL: 89 1W/1m
Bl: 16.9 Tesla Meters
Xmax: 21mm (one-way)
RMS: 800W
What do you guys think?
Thanks.
