Secondly, why pick the Q over the BL?? I've heard the BL or BTLs push air, and not much sound... That's whet I was told. Not that I would know. Now I ask you, what is the difference. I just know that's what ppl recommend. Do you have any subs you've referenced these to? I have never heard anything other than Kickers, I'm completely new to all of this. When you say hear all the notes...do you mean your highs? No, I've been spending time setting up my front stage. I want 20 - 100hz to be loud and accurate. Accurate as in my daily drive I don't bang the music much, But when I'm in the mood to bang it, it shakes the car and sounds Loud but still good. or you just mean not having a peaky, one note wonder box? Yes, I'm getting my box made by Pound That Sound, so I have to decide which sub before he starts making it. I just want to be happy and not regret getting something that don't perform and sound grate.
