jsautter,
I disagree. The Harbeth SuperHL5plus that I owned sounded excellent with all genres. A very balanced, neutral and revealing speaker (which employed it's lossy approach to actually achieve this balance).
How thick should the front baffle of speakers be?
Some manufactures advertise or hype a thick front baffle, two layers of MDF, if the woofer is as thin as paper cone how could it change anything. Could be just hype
