    Finding the right cabinet design for the right driver

    They work better in a sealed enclosure. Look at their BL number. That's motor strength. Or look at the size of the magnet structure. 45 pounds is quite large for a 3" coil. I also have a custom 3" coil sub that has a magnet structure that is close to 60 pounds. It's more about the enclosure than...

You can't even get a TC-3000 any more. Parts Express sells the Axis model now. It's close to the 3000 but with...

    Not even close. The enclosure is ported and based on the specs of 36hz it is probably tuned to around 40hz. It doesn't matter what the driver is rated for. Sending information to a sub below the enclosure's tuning frequency is a recipe for disaster. Look at the Thiele/Small parameters on the...
