Thanks, as usual, for all the great info, Ilkka. Would just like to point out that, according to Linkwitz's closed-box
spreadsheet, 100l is good for something like 6% air-spring distortion at the LMS-5400's maximum displacement, which, if true, makes this result even more spectacular. Not sure if this chart is really for constant 110dB SPL at each frequency, or if it's a plot of the distortion along the "110dB SPL" curve from the Maximum Output Level chart, but either way, the box should be doing some damage...
