nice not only does it have a duck but a ZX5 focus :D

Yep it is a Focus.

The system is 4 x JBL GT5 10's of 1200 WRMS in a 33hz tuned box.

SPL testing with/door window open (louder on the lows).

Peak=142.7dB @ 37Hz

40Hz=141.8dB

33Hz=142.5dB

25Hz=138.3dB

20Hz=138.7dB

So it plays quite flat!

Blocking the port to tune to 20hz makes it do 140db at 20hz.
