The Critical Q Sub-Woofer

Box Construction Page

(Under Construction)

Earlier Sub Plate Amplifiers are no longer available. But PartsExpress makes what looks like a suitable amplifier, part number 300-804. According to the PDF file, the stock unit without any changes will give you good all round performance being -1.5dB @ 20 Hertz. But if you limit the subwoofer for only audiophile use, change R35 from 24K to 15K and R36 from 150K to 470K.

The box cut-out for the amplifier now need to be 216mm by 216mm.
