The Volume and Crossover Frequency Controls together with the Phase Correction Switch allows the sub-woofer to be set for a desired sound.

Recommended Project Idea:
Purchase an A 2451 and 2 x C 3088 8" Woofers. Ideal combination for a D-I-Y home theatre subwoofer. The 8" woofers employed result in a compact enclosure that could easily fit behind or next to a couch.

This project can be built to the following specifications:

40 litre enclosure
70mm diametre port
100mm port length

This results in a sub enclosure tuned to 45Hz.
