It's a good time for those of us with limited woodworking who wish experiment with small sub-woofers. With the rising popularity of sound-bars bluetooth sub-woofers, consumers are throwing out some good stuff.
My 2nd favourite commercial cabinet is the 17 litre LG SH54P-W. I have purchased TWO of them for less than $20. They are good-looking enough and I couldn't build my own cabinet for half the money. I had intended to replace the 'blown' 7" driver with an 8" - it's tight but there's room. With very little pressure applied the driver sounds makes a 'slapping' sound like it has reached the limits of its excursion. In free air the driver exhibits no such behaviour.
Calculations reveal the overly large port is tuned to around 65hz. Could this be the source of the problem?
