[QUOTE="Carl Klinkenborg, post: 215200, member: 12770"] For a few years I've used 4 x 50l sealed 18s crossed over at 100Hz with about 2kW per pair, which just keep up with Beyma TPL150H/Beyma 10LW30N tops (20l ported 80Hz). I now find it very difficult to listen to any system using ported or horn-loaded subs, such is the accuracy of sealed subs to my ears. One of my acid tests is double-pedal drums such as used by Metallica, which comes through as the brutal machine gun-like staccato it should, not as a transient-blurred phrrrrt-phrrrrrt sound most usually reproduced. (Please don't for one minute think that this genre is all I play!). To my mind, the lowest possible stored energy in a subwoofer system is crucial, but both relfex and horn subs have it in droves. It is super-quick and easy to build a trial sealed enclosure. Try it - and with the correct EQ and power you might like it! [/QUOTE]
