back chamber (Oris Horns)
A guy I know has horns similar to 150's with Lowther Pm2a's ( i think) and likes them open at the back I.E. no back chamber. Has anyone tried this? What does the back chamber provide?
My play with open baffles speakers revealed a more open and free sound compared to similar cost box speakers. Less colouration. I have enjoyed electrostatic speakers so maybe the flavour of dipole speakers is to my liking.
