I have just finished installing, calibrating, and am beginning to enjoy my new Ht, thanks again to this forum for all of the great help. After alot of research I now own HTD level 3 package (w/ the inceiling for the rears), Panasonic XR50, Pioneer 563, and the Dayton Tiny Mighty. I received my copy of DVE yesterday, and using the RS Sound meter calibrated it this morning. I have read that the DVE can give different readings for the sub channel, but it all sounds good, even to my wife. The only thing is that I bought the sub as a hold-over until I could get what I really wanted, either an SVS or a DIY. I like the look of the cylinder subs, but..... Now my question. I have the gain set in the sub at about the 11:00 position. What do I gain by buying a bigger sub? If I need more bass, shouldn't I just turn up the gain a little more? I'm not sure if this makes sense, but in my mind the better sub will only yield more bass. But if the calibration is telling me to keep the gain turned down, what do I end up with? Sorry if this is confusing, but I need some clarification.
