So was I Fred. I guess there just isn't much material that hits loudly below 20hz, or at least not in what I listen to/watch regularly.
Which is what I was saying in that other thread about the EP350 vs the competion, the lower extension really isn't noticed sonically but I believe it is noticed via lesser vibrations with the EP350 and EP600. The lower extension is more of a subtle feel than a blow you away sound, IMO.
