Tech Tips/Secret Stuff
T
here are all kinds of ways to design subwoofer enclosures. Nomograms, charts, on-line design
software, etc. But the BEST most consistent PC software is available...and better yet....its FREE!
And it has been available for over 10 years.

1. Use 3/4 in or thicker MDF, or Baltic Ply (perfered)
2. When in doubt BRACE! Woofers can produce MORE than 10 pounds per square inch of pressure!
3. Always deaden the interior (if possible) with deadliner, DynaMat, HushMat, etc. Make the
enclosure as dead as possible.
4. Stuff enclosures about 1/2 to 2/3rds full of polyfill. BOTH for vented and sealed!
5. IF there is a choice between vented OR sealed. For a normal human being...go VENTED!!!!
Sealed? You need 4 times the energy (power) to get to the same place a vented can get you.
And some of the most expensive home speaker systems in the world...use vented enclosures!!
(HINT: only put in 4 of the Theile/Small Parameters - Fs/Vas/Qes/Qms)
IN THIS "SCENARIO" A 0.4 SEALED VS 1.0 CUBIC FT VENTED ENCLOSURE
VENTED IS +9 dB more output for every watt put into it!!
