Cutting the Shell

Cutting the Interior Braces



Two of the braces Cut



Legs v1.0. These were the first round of woofer-legs I bought, purchased them from Home Depot and trimmed them for about 3 inches of clearance between the cone and floor. We'll come back to these...



The final trimmed legs



All of the MDF cut to size - Note: the corner bracing is marked where the center brace overlaps, this amount of overlapping must be taken into account when calculating your box volume

According to the Q equations from Rythmik, I need exactly 3 cu. ft of air surrounding the driver. Here's the math:
Total Interior Box Volume:6762.766"^3
Total Volume of Driver: 871.873"^3
Total Volume of Amp: 406.0625"^3
Total Disposable Air: 5484.8305"^3
V of Tall Brace: 263.484"^3
V of Side Brace: 277.922"^3
V of Tall Brace: 263.484"^3
V of overlap on Side Braces: 2.8125"^3
V of overlap on Tall Braces: 2.25"^3
(-) Necessary 3 Cu. Ft of air: 5184"^3
= -498.9965"^3

So, 498.9965"^3 is the net volume of air that must be displaced, save for the 3 calculations below (the base MDF to be removed from each Brace):
V from Tall Brace 1: 102.75"^3
V of Tall Brace 2: 102.75"^3
V of Side Brace: 190.8517"^3

This brings the total volume of MDF that must be removed (after the initial removal) from the braces to: 102.6448"^3

The interior braces and their air displacement - the goal is to keep them sturdy while still removing wood for air, while keeping the box the target size.
