My current subwoofer system is based upon (4)15" Adire Tumults.They are sealed.Two per cabinet in separate chambers.
I use (4) QSC 1450's, bridged mono to each Tumult.They have a relative high F3 (around 38hz in a 3.0 cu. ft. enclosure).To counter that rolloff I use a Marchand BASSIS to extend the bass down into the 5-8hz range.My Behringer 1124p is used for one bad room mode.
WTS, deep bass really fills the frequency response.There is information down into 8hz that needs to be felt not heard.There is an energized feel when the room pressurizes.It's almost like surround bass.In WOTW the lightning strikes are around 8-10hz and at 90db it hits home and gives you that feel that a 20hz high pass does not.
Make no mistake getting down that low is a DIY job if you don't want to go broke.I don't know of many subs capable on the commercial market that can get that low without a mortgage attached, if at all. I'm not sure the return is there for you unless you feel it for yourself.it's a personal thing.If I'm going to buy a DVD I want all the sound....even down to single digits.
Enjoy..hope this helps KG
