Mike,
I would certainly not argue with the experience you and Ivan probably have that a
horn loaded sub can be flown with much better results than a front loaded sub.. just that I have only ever seen ONE system with flown subs that worked properly. And I would certainly agree that having a boundary, such as the floor, for a front loaded design box seems to mitigate a lot of the issues that flying creates for that design type box.
Another thing, though, is I know I see riders that say very clearly about NO FLOWN SUBS.. probably because they are thinking about conventional front loaded boxes sounding so poor up in the air.
Anyway, I'm not contesting your experiences.. only relating mine.. which I have not had the privilege of getting to work with as much in fine equipment as you all have.
Regards,
