Hey guys I currently have two sealed Dayton 18HO's powered by a peavy IPR2 5000 and I am using a behringer FBQ3102 to EQ them. I plan on building two Martysub boxes to replace the sealed boxes. Are there any different settings on the EQ that need to be changed for ported subs?? is there something else I can replace the 3102 with??
No, the settings will most certainly need to be redone. As BassThatHz mentioned above, you really need a measurement mic, such as the UMIK-1 or UMM-6 in order to take measurements and adjust the EQ accordingly.
