I decided to frankenstein an Altec Lansing horn to pretty much the PM90 design, changed it a bit to accommodate the horn better (it'll get some color soon...). It was a pain to attach it and even though it's partially in the way of the sound path of the 12", it doesn't seem to affect it audibly.I still have to tune them, but boy do they sound good already.[ATTACH=full]209356[/ATTACH]
