Dual tuning and a 350w amp. Are you planning on using the Rythmik with the selectable SSF?
They model very well in home theaters. I've only played around a little with my 1001's and 1201. Nothing serious. From reading multiple forums over the years, the 03 series requires much more than 350w to get it going.
As for "best of the best", not really. They are always a great value. They some from the same build house that used to supply SVS with their ISD driver. And finding out that I had some XBL^2 equipped subs was a nice surprise.
