Sub Upgrade for Music and Home Theatre

I second Sugarbrie on the REL. Also check out the Thiel SS2.

The Aerial is VERY good and has great looks as well. The xover built in is very flexable and you can run a sub level in at the same time as a main front in so you can calibrate for both theater and music a little like REL does. The Velodyne is just loud but not very clean or fast and always sounds like a subwoofer. I call it the high end Cerwin Vega. I think you should look for REL as well. Anything at or above the B series but not the Q series. I think the REL is better than the Aerial but you can't go wrong either way.

Take a look at Essex Audio SW-3. Very musical and plenty of power for movies.

You might check into the Parts Express/Dayton Reference 12" subs with 1000 watt amps.I'm using a pair of their 10" Reference/aluminum woofers in my AV set-up.Great with music and LFE effects.Articulate,quick and detailed.The "high fidelity" series will be more to your liking than the "high output" woofers.

One reason I like the REL's other than the performance, is because they have two sets of inputs and controls that can be used at the same time. You can set the subwoofer for music through the high filter and for HT through the low filter and forget it.
