[QUOTE="Peter Morris, post: 148707, member: 652"] Re: New DIY Mid High With a 4[SUP]th[/SUP] order crossover there is 360 degrees of phase rap. Add to that phase caused by the porting of the double 12 horn i.e. 180 degrees at the box tuning frequency … and the then at the other end, the phase caused by the HF/VHF crossover. [/QUOTE]
