Has a hybrid Horn/Bass Reflex design ever been tried? More specifically, using a PVC pipe inside a Bass Reflex speaker box. See the attached crude drawing.
Hi Juan,I bet it works far better against a wall at ear or chest level than simply in the floor.
I'd guess you could call something like the Metronome a combined horn / vented box. Expanding TL geometry terminated with a vent, I'd guess its pretty near.
Man, I can't tell you how many speakers I designed, years ago of course, long before the internet or even the T/S parameters for that matter, only to get a little older and discover they were built long before I put pencil to paper. About the only one I know that has worked well and that I have not seen anywhere else is this one.
