[QUOTE="hispls, post: 8831357, member: 614752"] I think the difference may become audible (greater than 1dB) much more quickly than you think, both in output and in creating distortion. I had a reliable source explain to me the math behind predicting this sort of thing and it surprised me when he threw out some numbers about how little panel flex it takes to become audible. If spending money for weight savings and making your working with the material easier is good enough to justify the cost for you, it's all good, you get to prioritize the cost vs. value of those features. Just so long as you don't get the idea that it's going to be magic and negate the need for more thickness and bracing where appropriate. Bear in mind the exponential scale of deflection vs length of the panel as you go. [/QUOTE]
