I fully applaud this man on his 200w efficiancy thing, but have always wondered the sanity of horns in a house.
As for mid tops, well those low power fast drivers in the scoops probably go up very high?
Correct me if I'm wrong, but is that also a turntable I see almost touching the right speaker building ?
Of course a man is free to do whatever in his house, but when the picture is put on a forum, questions will get asked..
IMHO, to fully appreciate any time of scoop cab, you need to be at least 10M back, with no LMS, his "mid tops" , will b arriving at his ears before the sub, so he'll be adjusting the volumes to attempt compensating for this.
Meanwhile, a fully reflex system, would have him thinking he's standing directly next to the conductor while playing "Prokofiev's Dance of The Knights"..
