I have a pair of PPI Pro 124's that I am going to be running off a MB Quart DSC 1500.1. The thing I want to know is if anyone has experience with these subs, especially using a ported enclosure. I have heard that they can only be ran sealed so that is why I want to know if anyone ever did port them and how did they sound?
