Is it possible that the higher frequencies travel through the air more easily when the way is cleared by the low frequency waves? In other words they "draft" behind the low waves with less resistance.
How can a subwoofer expand the soundstage?
I have recently added a Rel Storm III to my two channel system (Essence Sapphire amp, modded Essence Reference Super Gems, Arcam FMJ 23T CD, SOTA Sapphire TT, Benz Glider, Audible Illusions Preamp). I immediately noticed an improvement in imaging and depth of the sound stage at all frequencies. The REL manual specifically mentions these benefits. Can someone please explain how adding a driver that's designed to play at lower frequencies can have this kind of impact? I will NEVER take the REL out of my system.
