how does it sound like? that sub is TS-W121SPL right ? i just bought one , powering it with pioneer 1000w rms amp 4 channel, but i still dont know which design i will use for the enclosure, (clean it al lil bit , i gave u 10 , so that u keep inventing stuff,
The sub is a TS-W305DVC 800 Watts max, Its loud for one 12. The reason for the ports coming out the front is because I tuned it so low and my friend I built it for didnt want to spend money on elbow pipes.
The box is 3.4 cu. Ft. the first chamber is tuned to 28Hz and is 2.2 cu. ft. The second chamber is tuned to 48Hz and is 1.1 cu. Ft.
I think if you are going to use a ported enclosure make a ABC box (double-chamber reflex box). if and one needs help making one just ask.
