Someone mentioned that a good "musical" sub makes all the difference in listening to concert DVDs. So what makes a good musical sub? I'm trying to figure that out. I figured, so far, that a sealed sub has, overall, lower group delay (i.e., tighter bass). I noticed that my Dayton 10" gets pretty fat when i turn it up. I really notice it when it comes to bass drums - the sound lingers too long - THuummp instead of THUMP!. Thats what it sound like even though the frequency is flat (relatively for my room) from 25-100hz. I turn it down for a more natural sound (to my ears). Can a ported sub be a "musical" sub? Kindof a loaded question, isn't it:b SVS guys feel free can chime in as i may buy a SVS sub in the future (as a ported musical sub).
