Most installs you've heard are like that because fucking morons insist on making a sub that will get low naturally just play stupid low and not be able to play the higher range. Put them in a good box and you'll be happy. I heard an X that was flat all the way up to 50hz or so.

"Due to the extremely low level of suspension induced distortion the typical "punchy" upper-bass peak in the 40s-60s Hz range that occurs with traditional woofers when pushed to high excursion does not occur. This "punch" is caused by a tightening of the suspension over stroke leading to increased FS and Qts figures -- in other words it is distortion that some consider to be pleasing; but distortion none-the-less. "

DD is overpriced
