DIY subwoofer parametric equalizer

SSassen · 1st June 2005, 02:37 PM

I'm embarking on a new subwoofer project with the Adire Audio Tumult 15D4 woofer in a small closed case powered by a high power class-D amplifier and using LT to EQ the response and a accelerometer on the woofer cone to further optimize THD and EQ the response flat.

All of these parts are more or less drawn out in their rudimentary forms but what's still missing is a means of room correction, so I would like to include a parametric equalizer. Has anybody ever built a parametric equalizer with a high Q and hence a small bandwidth so as to equalize the 10...150Hz range?

Best regards,
