I have the REL Q150E subwoofer, and wondering if I've set the "Lo Level output" correctly. On certain films the subwoofer reacts perfectly to appropriate moments, such as the Death Star exploding in "Star Wars", the rebel base at Hoth exploding in "Empire Strikes Back", that first spinosaur roar in "Jurassic Park III" making me feel the air almost blow past me, etc. But then there are other moments when I would expect to feel some subwoofer effect but I don't feel anything at all; for example, during "Godzilla" (UK DD 5.1 version) when the mayor is giving his speach and it gets interrupted by Godzilla's footsteps in the background, through my REL it doesn't at all feel or sound as heavy as a 200 tonne monster, I feel no vibrations at all unless I turn by subwoofer up a lot....but then that increases the bass too much for other films where the sub is already working well for. People tell me that I'm supposed to feel the footsteps at that point in the film. Other "missing sub" moments are include "Aliens" when you hear the aliens banging on the pressure-door and Hudson comments about the loud noise they're making....a "loud" noise which just sounds and feels like little taps unless i turn my sub up to unrealistic levels. Does anyone else have the same problem as me, or know if I'm doing anything wrong with my setup, so I can resolve why I'm not always getting the desired effect? Here's my configuration: Amp: Denon 2802 Speakers: Mission M72 6.1 package, centre sopeaker replaced with MC2 Subwoofer: REL Q!50E Crossover: 80Hz Subwoofer output level from amp: -2 dB (85 dB on SPL when running test tone from amp) Main and centre speakers set to Large, surrounds set to small. Settings on subwoofer: Lo level = half way; mode=2; slam/depth=depth; connection via IXOS subwoofer phono cable from amp to sub's 0dB socket. Thanks.
