I owned 1+1s a long time ago. You definitely need a "fast" musical sub. The REL used to be the standard, but the ACI Titan II LE has really passed it by. At $1100 direct it is the new reference in musical subs. Has about as much output as the $2500 REL. Very fast and defined. Built like a tank with a gorgeous furniture grade cabinet. I have done extensive comparison with the REL, the Titan II is clearly better at less cost. Got mucho applause in the latest issues of Positive Feedback, Bound for Sound, and Soundstage.
