Rear Center Console

I got the shop turned back around to wood working, so the rear console was first.
Because I have gone to alot of trouble to insulate the trunk from the passengers compartment, sticking any sort of speakers back there makes no sense. Come to think of it sticking speakers back there never made any sense to me if you had a back seat.
Also while I will have a very nice sound system, I will not be putting thousands of watts into this small space.
I have aquired 2-6"x9" triaxiels for the package tray, 2-4" Bi's to replace the 4"x10"in the dash, and 2 -4" Bi's for the door panels, Im not inclined to put speakers in the kicks.
All of those are fairly straight forward.
For the Sub-Woofer frequency range I will be running 1-6.5"MB-Quart. For you speaker guys it has an Fs=34Hz.
It only takes 150Watts RMS, and will out perform 3-12" 150Watt speakers.
One of the things I have been doing for the past 20 years is designing and building large front of house systems say for 250 people and up.
The secret to getting great sound, is efficiency.
There is a design called a folded horn that if built correctly will produce 5 times the SPL at 30% of the Wattage using a conventional box.
Now there are folded horns and there are folded horns, what makes one efficient is the lack of square corners and a proper horn flair for the frequencies desired. The ones I build are based on a design called "snails". A pair of subs for large venues takes 60 hours to produce.
The single cabinet I made for the car took 16 hours.
They are a real PITA to make which is why you cant go out and buy them.
Here are the pics, first is the pile of parts for the one box, next is the bottom, then the throat and duct assembly, then one side with the bottom & back attached showing the gussets for the corner pieces. the next three are views with the final side missing and then one of it in place.
I will paint it black, cover the exterior in carbon and put a padded arm rest in place in between the seats
