You have to be kidding..you guys are not use to real bass..

EV sub @-3db range is 53hz to 93 hz.....@-10db range is 44hz to 118hz..

You may as well use a Bose ...If the roll off is 100hz..@ -3db there is a hole in the frequency range..just like Bose..

I'll take an old Cube ..3 way and woofer goes down to 38hz..and full range to boot..

Guys you better rethink why you need a sub woofer

20-25kz is sub range...

No wonder Donny is cutting bass, he isn't use to real bass on the floor...Don't judge bass on the stage or front row at a nursing home
