Licensed to ass kick ...

First, the technical background to expand with this subwoofer: 35m² wooden rooms in the old building (half-timbered). Tower speaker from Celestion F30 F20 front rear, plus two F35C than Surround Back and a Heco Victa 100 as a center. previously the bass was supplied by a vicious K300 SW. This was already making good pressure, lost, however, by the Downfire principle in conjunction with the wooden floor much power to the "walls". For ES250P here do not in any trouble. Despite the problematic circumstances you do not need a time 50% of the power controller to the kick in the middle of the abdomen to get. Really I was surprised, however, that the sub can not only strong but also while remaining clear of roar was so far nothing to hear. Some scenes like the appearance of the T-Rex in Jurassic Park or the Pod Race from Star Wars Episode 1, it is very hard to get the smile off his face again.
For home theater thoroughly recommended.
