How is this different from the other b22 plans I had modified it so that it would play lower bass than expected.
I did some modifications to get 147dB
The original one was 143dB
I really loved this bandpass subwoofer box cabinet it shakes me in a distance make sure to use the B&C Speaker 18DS115 to have its maximum performance.
Frequency Response: 32 Hz - 90 Hz
You could change the bracing dimensions in case your speaker's mounting depth was too deep so that it would not hit any wood and you could fit it perfectly.
This is a line array subwoofer.
