Hey, I had a question about this because it concerns me. My plan is to buy four tops (PRX 612m's) and two XLF xubs for the front end. However, some reading I was doing and someone on another forum in a PM had mentioned that the PRX horns have a 90 degree coverage pattern and that having two per side would cause certain sonic interactions and anomolies and cancelation in areas where they intersect and that the lower frequency drivers would do this as well but not to as great a degree.
He was saying that if I want to have multiple speakers per side that I should look for speakers with a 40-60 degree pattern to avoid falling prey to these issues.
Any suggestions here?
