I am totally new to the open baffle modeling process. I have gained a very rudimentry understand about what needs to happen by reading from John K, Martin King, Linkqitz, etc...
I am setting out to build a first attempt at an open baffle. My budget is tight and I want to go all passive. I really like the idea of minimizing radiated energy into the room via di-pole cancellation.
I own the following drivers for one pair of speakers:
2x alesis 5.25 http://www.parts-express.com/pe/sho...tnumber=299-160 (Nearfield FRD Attached.)
4x no-name 12" woofers (qts = 1.2) http://www.parts-express.com/pe/sho...tnumber=292-320
4xDayton ND20fb4
I really would like to find the best tool for the modeling process. AJINFLA explained that the X-Baffle and the Response Modeler do not account for the H-Frame specific properties. I assume the H-frame has some level of pressurization that is independent from flat baffle designs(Pressure cavity?). I believe that both programs do account for the di-pole peak. THe response modeler 2.1 was just released today with this mod. (Thanks Jeff!)
I was thinking a nice starting point would be: (MDF)
--woofer baffle of 14"x30"x.75"
--two wings 8"x30"x.75".
--The top and bottom of the hfram would be covered 15.5"x8"x.75"
--Open Baffle for mid 12"x24"x.75". REsts in the middle of the h-frame
--Tweeter (Dayton ND20fb 3500hz) at 16" on open baffle (Rear firing tweeter is mounted on additional back baffle piece.) wired in series with rear firing out of phase.
--Midrange at 12" on open baffle
--30degree angle brace from h-fram rear to open baffle rear.(pine 1"x4")
