I am redesigning my sub bass system in my 2008 Hyundai Elantra. I currently have one SSA XCON 15" in a 4^3ft net enclosure tuned to 32hz. I am pleased with the output of the system but the enclosure is too big for my trunk area, I need more cargo space. Since I am redesigning the system I would like to achieve a smaller enclosure with more output.
For amplification I have one Crescendo 3kwp which is capable of approx. 4000wrms @ .5 ohm.
I am considering two TC Sounds Axis 12Q1. Each driver would be in it's own small sealed enclosure.
What is the optimal sealed net enclosure size for one Axis 12Q1?
Power handling: 1,000 watts RMS/4,000 watts peak Le: 8.7 mH
Impedance: 1.2 ohms per coil x 4
Re: 4.74 ohms
Frequency range: 15 - 150 Hz
Fs: 27.8 Hz
SPL: 85.4 dB
Vas: 1.41 cu. ft.
I am no pro at enclosure calculations that's why I ask!
But based on my calculations a qtc of .707 gives me a vb
and a f3 of 54.9hz.
Isn't that enclosure size extremely small and the f3 high? I want good low frequency extension to 20-30 hz.
