Katylied,
Actually I wasjust playing around with sub settings (one of the reasns I love and hate subs...) And changed the crossver from 85hz to 130hz. Wow! I now have some of that mid-bass slamm I've been wanting..playedloud u cann feel it in your chest. Since this most, linn ahs confirmd the update to the 242 is quite signifigant, and probably plan to go for apr of these. Many speak highyl of the olderversions, and the newer ones are to be a large step in performace ahead. And they go to 49hz vs 70hz on the 212. So I'd probably keep the 221 anyhow. And yes, the akurate sub is a great sub. Many speak negatively about it stating they can't even tell if its on. A good sub shouldn't draw attention to itself, just when you turn it off. And when itson it not only improves low end, but everything. This is the fastest sub I've known, and is capable of good pressurization as well
