3 Layers in total make up the front baffles...





The inner most edge has a 1/2" radius to help air flow at the back of the woofer




Offering up the baffles to make sure they fit










The weird cut outs I showed you before, are the braces for the inside of the box as well as the magnets as the subs weigh around 40-50kgs EACH! Not only are the 18" in diameter....they are nearly 16" DEEP!!!! Imagine the leverage weight on that!





And test fitted with the port




The back panel was then glued up




And joint the rest of the box!




Time to strengthen the top of the box!...An extra 2" of MDF going in

Time to get the braces in to firstly, support the subs, and secondly brace the box BIG time!

Get some angle steel (which is rated at over a ton IIRC!)


Cut it to the right lengths


Bond it to the wood


Then screw the steel to the MDF using HEAVY duty coach screws

Time to fit the braces!






As you can see from the pics, the braces are 2" thick themselves...and are braced further by the steel sections...I dont think this will flex! If it does, ill be in serious shock! Steel/MDF is bracing the side panels, the port, the floor AND the roof!!

Port was also specc'd and radiused...

[teamSPB]

Time for some pretty panels to be mocked up














Then it was time for some flock! MASSIVE MASSIVE thanks going out to Mike and Nikki here...they are awesome at flocking!

Only have one photo of it so will need to check my camera to see if there are more photo's...if not ill take some more...

[teamSPB]

Damn thats crazy.
How many db are u lookin for when its done?

Im hoping for around 157-158db fingers crossed! HOWEVER, im not building this for numbers...infact, there is alot riding AGAINST it doing big numbers...the cabin is HUGE...Honestly..the space I have left in front of the wall is probably the same as a Polo inside! Ontop of that, my tuning is pretty low (30hz)...

I built this to play music and play it loud...I listen to alot of dubplates so the lows was a priority for me...oh and to be like a wind tunnel lol!!

I just want to have fun with the vehicle..play loud when I want...and scare people left right and center lol!
