I currently own a Kenwood 103 10" sub. Nothing wrong with it, love the sound, but it's not magneticaly shielded. I'm thinking about replacing the unit with B&W 300-series sub (about US$280 street inlcuding our 15% taxes). Any comment about this sub? or any other subs, for that matter? I don't like boomy bass, I like accurate bass. A bass sound that's supposed to be 1 second long should last exactly that, not 1.2 seconds. An acoustic double-bass should sound like one, not like electric double-bass. Something that supposed to sound like a "bup" should not become "boop". well, you got the idea.
