Very very very pleased.
Just received it. Had it in a 1.9 cu ft ported box tuned to 33hz and it hit hard. Had a minor air leakage and it started sounding sloppy :-(
so I went and got a temporary sealed box while I get my custom ported box built and oh buddy. It sounds **** near better.
Nice subwoofer for the price. Got 1 being fed 500 watts and it slams.
Will get another in the future.
