Has anyone measured the vertical off axis response of the Statements or similar speaker with mtm mids and a high crossover to see what effect the mid's ctc spacing of nearly 3 wavelengths has. Do you notice any comb filtering when standing up and sitting down again with these speakers? I am considering a similar design with an XT25 and twin RS100 but wonder if I might have to use a better tweeter like the Scan 6600 in order to cross lower.
