@deep_333 Thanks for the link for the rythmik F18 sub that looks like a solid possibility. A pair of those should do a decent job of energizing my theater room. Certainly gonna put those on the list. The ascendos, if you look at the specs are 15 db down at 30 Hz, so they wouldnt be on my list.
@devinplombier The lack of distribution in the US is a non starter for me...there are enough things to juggle to try to get a house back in livable condition that taking on the hassle of trying to get something shipped from across the pond kills that as an acceptable situation.
@mark200mph - my dad was a physicist too :) and I agree that we should just enjoy the music. God knows there is enough good music to listen to I will never hear it all.
