its safe, why would you not want to play below tuning at all?hmmm dont think thats too safe. i have tested that and i got more stink playing under tuning than at/above tuning
2 HDC's off a single 2200 won't be pushed hard enough to hurt themselves playing below tuning...i could help ya maybe this weekend man. make sure your subsonic is at your tuning freq not below for whoever told you that. set you lpf to about 60 and set you gain up at around half. if nothing still then post on here and let me know how that went
Give me a call in the morning ,417-859-6025, and I will go through the set-up with you.anyone?
