That's a valid point. There are tricks to making a Wuhan project better. It's better to keep the gong hung closer to the floor. Many orchestras hang them a bit high, so everyone can see it. The same thing is true in regards to how you face the gong (Wuhan). While it's more difficult to see, a Wuhan will sound better if you have the flange end facing towards the audience, and the not the front of the gong. The Vienna Phil. seems to understand this point. Also, many players use mallets that are simply too small for effective fortissimo smashes. To my ears, the Concertgebouw seems to have that problem. It comes out sounding more like a hard bass drum 'thud'. Percussions spend hundreds of hours perfecting four-mallet playing on their various keyboard instruments (two mallets in each hand), yet spend little time listening to, and tweaking, their craft when it comes to 'utility' stuff like gongs and such.
