Just got my stuff installed, orion 1200d powering a orion h2 in 3.25 cubes @ 31 Hz. Since i don't have my HO alt yet i put the gain at about 1/4th, figured that would be fine until i get the alt, then i will set it right. What i was wondering is, is there a subsonic filter on this amp??? (can't go look right now...) and if there is what should i set it too, since my box is tuned to 31hz. (wait would the subsonic be the same as the HPF that it has built in? same thing basically, but does the HPF go low enough???)
