I have a large listening room which needs several sub-woofers to give
adequate bass. I am only interested in the range above about 32 hz.
When I play some recordings with organ that have strong output below 32
hz, the woofers give signs of distress. What is the best way to reduce
the input to the subs below 32 hz?
