I’m guessing you meant un-equalized CS 1.2’s?
Checking the eq is a good suggestion. I’ve never had a problem with mine, but in the last 30 years there have been some reports of eq issues. Your available power is just about the minimum suggested for the 3.5’s, but it is a small (and not ideally proportioned) room, and that might the reason for the limited bass response. I’ll hazard a guess and say the 40 Hz setting will probably work better in your room.
