JBL LSR305 (1st gen) quasi-anechoic measurements

[dominikz]

I captured a quick measurement of my own first generation LSR 305 and the result matches that of @dominikz very closely. It appears to be waveguide cancellation.

BTW, do you plan to do a full spin of your JBL LSR305 at some point?
Would be very interesting to have another independent measurement to compare with - especially one with more midrange resolution (such as yours)!
