A little EQ to bring 20Hz up about 4-6dB, and no one would turn this bad boy away.

3rd order distortion is really low. That has to be a really clean sounding sub at normal listening levels.

It was my intention to measure this with some EQ too, but unfortunately the surround gave up during those measurements. Maybe next time.

The news ones have a better surround to handle more excursion. I think the ones built after September last year. I bought mines last month and it has it.

Yes I know that. I have new top assemblies with those high roll surrounds on the way (TC sent them since this one had a manufacturing failure).
