So I finally was able to locate the old manual. And the manual does indicate that the left/right speakers are M1Ti. Cover says Millennia Ti, Vocal.Point, Epicentre, Quadrant, Epic.

I feel that 20 years with this speaker set is enough and dont feel it fills the room with enough sound when watching movies especially. Its time to upgrade. I recently upgraded my receiver to an Onkyo RZ820 and my TV to a Sony 930D series. My TV room is in the basement and 15ft x 14ft, with one side completely open to a bar area. So unfortunately, for a 5.1 setup like I have, the surround speakers are on the back wall.

I have done the auto calibration of my speakers with the Onkyo many times. Yet I still feel I dont get enough vocals out of the center channel or background out of the surrounds for this room.

Where do I go from here?
