I've done the search, I've read the primer, and I guess I just don't have the ears everyone else has. I have a Adire Rava sub (just hooked it up , thanks to ya'll for your help!) 2 mini-monitor mains, and an Onkyo 696 receiver. I set my mains to "small" as this forum suggests. The Rava manual says to start with the gain, turn it up till it sounds too "boomy", and then do the same with the crossover, and then do the phase knob until it "blends in". Right. I can't tell if it's blending it...I don't even know what that is supposed to sound like - I don't think I can even tell what it's doing! And what is "too boomy" anyway? Someone on one forum suggested that I set my crossover to 80. How do you know where that is? Only the min and max are marked - do I just estimate where that is? Is there some other setting that I am supposed to make on the receiver? If so, how do I get to it, cause I sure can't find it. I'm just so disappointed after all the posts that I have read, that I can't make more sense of this. And I thought I was good at this kind of stuff. Oh well...humbled again. Also, is the goal to get the settings done, and then leave it? Or do people change them depending on their listening mediums? That would seem like a pain, I'd rather "set and forget". So far, I have ony listened to music with the sub, and yes I can really hear the bass, but since this is my first sub, I just don't know what is right, or what is too much. I haven't tried a DVD yet - maybe I should try that. Anyway, I appreciate whatever advice you can give!
