      Cup Diameter

      The Monette Unity TS6 has a cup diameter of 25.40 mm / 1.0000 in compared to 25.00 mm / 0.9843 in on the Denis Wick 9BS — a difference of 0.40 mm / 0.0157 in. A wider cup generally produces a fuller, darker tone but requires more air support.

      Cup Depth

      Both mouthpieces share a medium cup depth, so the sound character from depth alone will be very similar.

      Throat Diameter

      The Denis Wick 9BS has a wider throat (6.66 mm / 0.2622 in vs 6.63 mm / 0.2610 in). A wider throat allows more air through, increasing volume and projection but reducing resistance.

      Neither mouthpiece clearly dominates the other — the right choice depends on your embouchure, playing style, and the sound you're after. Try both if possible.
