My impression of my Wick 2, which is the same as a 2L, just the difference between the smaller Besson receiver and the standard American receiver, is that the 2 is rather Bach 18-ish, with a rather rounded, moderately deep cup that provides a brighter tone compared to my Wick 1, which has about the same rim, but has the deeper Helleburg style funnel cup, though not quite as extreme, think a little bit of an inverted arch more than a straight funnel.
If anyone is in the market for a Wick 2, mine is for sale. PM me for details.
