My last year project, a DIY Subwoofer based
on a 100W plate amplifier and 10" subwoofer driver.
Size 16"w X 12.5"d X20"h, approximate volume 50L.
Material-3/4" High density waterproof fibreboard laminated on both side (for wet kitchen cabinet application)
Design-tuned port with adjustable port length,currently tuned at 19hz for music listening.
Cutting- the board is so hard that jig saw or hand saw is a complete no no.
i have to use rotary cutter to do the cutting.

Putting the pieces together using industrial grade wood glue.
Binding posts are mount directly on to solid piece of wood for maximum strength
and to ensure airtight quality.
Cross and horizontal internal bracing are added.
Note the 2 standing pieces of wood also double up as a support for the
woofer magnet to minimize basket vibrations.
Hard felt and recycled cotton felt are use in different side of the internal walls to cut down standing waves.
Internal wiring is QED.
Putting the last piece together.
I use 2 pieces of wooden Chinese chess bond together and grind to
the shape of cones for the enclosure footing (4 sets).
Veneered in black
Note the finished wooden "chess" painted in black.
The 2 pieces of cross bar are layered by foam padding waiting for the driver
to sit on.
Time to wire the driver
I lined the edges with rubber weather strips instead of foam as foam tends to
deteriorate or soften in time.
Putting the adjustable spikes in place.
The driver is positioned with the 4 screws facing towards the side walls and anchored deep to the vertical plane of the cabinet to add strenght.
Done! time sit back and enjoy!
