Dude! Hahaha... You learn finnish on the way too. Did this to my friends uncle a while back (well looks like 13 yrs) who publishes hifi magazines. Funny how you find your early "work" is still online and even usable...
.. and reminds you how many fucking years you have been sitting on this damn machine.
How much is that doooogy in the window, toot toot, I do hope that doooogy's for sale, toot toot.
Went to look at wood. MDF. 19mm 300mm 2440mm 8.27l internal volume.
If I were to be horribly and unforgivably stupid and ignorant I'd make it a cube. If I did that, the internal walls, assuming no stuffing, no bracing, no speaker back intrusion, etc, would be:
3√8.27 = 2.02225151688209 decimeters or 20.2225 centimeters or 202.225mm, which would be awfully difficult to achieve with 300mm wide MDF, even after subtracting 38mm + 4mm for thickness and sawcuts.
So given my lack of tools, it'll likely be 300mm ID one way, and 300 - 38 the other, minus 20mm square corner braces, gives us a cross section of:
(30 * 26.2) - (2x2x4) = 770 sq centimeters! DuckDuckGo fucking ROCKS! (mixed multiplication symbols and it still works!)
Converting that to square decimeters is 7.7 more math required:
<went to bed, got up again>
Volume of the bracing is ID of each dimension minus 4cm, times 2cm * 2cm x 2 of:
((30 + 26.2) - 8) * 2 * 2 * 2 = 385.6 ml
(0.3856 + 8.27) = 8.6556
8.6556 / 7.7 = 1.1241038961039
11.241cm / 112.41mm high which isn't big enough for the driver in question, so it'll have to be whatever the driver needs high, and tuned with sand filling.
Cuts are 50c each, and a little under 5mm wide, which is what I accounted for, IIRC.
Drivers arrived today! A little treat for Fred. So I went out and bought some stainless steel cap screws to match, and a bunch of various types of stuffing to fill the boxes with.
Need to pick up screws, Chinese jigsaw, glue, sliced MDF, and some square pine for bracing.
Also need to do work on the amp, or I'll never hear them...
Divided in two, so as to guarantee sufficient material:
4 * 185 = 740 + saw cuts
3 * 338 = 676 + saw cuts
2 * 300 = 600 + saw cuts
Per board @ 2440
If just what I really need:
8 * 185 = 1480 + saw cuts
4 * 338 = 1352 + saw cuts
Need to sort out a hole cutting option. So far a 35 euro ching chong router looks like the best (read cheapest) option. Might try to sort that out today.
