I finally got unibox downloaded so I got to see what the responce would be for the driver. I have a couple of questions. 1. I dont need a linkwintz chip like everyone was talking about earlier, a BFD should do fine correct? 2. Im aiming for a QTC of .63. A 16" I calculated should have enough volume (exterior) however, I want it as small as possible, will the baffle be big enough? 3. Im planning on buying the QSC RMX - 850 this should give me enough power to eq flat at 110db-112db at 22hz and up? I know the unit has a fan, but I heard it was dead quiet, is this true? I'm ordering the loudspeaer cookbook before I start building, so I may have more questions. Thanks for the help!
