What volume did you choose for those cabinets? Did you go with 9 CF like the 620? Where is the tuning ending up? Are those 5" ducts?
They are 9cf. Still tuning them. Trying both the markwart crossovers and some home grown before adjusting the port lengths. I hope to dial them in between 30 and 35Hz.
