just researching tonight and came across this difference... can someone tell me why the s26 is rated @ 48Hz (low end) and the S36 is 60Hz? i know this is nitpicky - but usually when you spend more on the same mfg. it results in "more" frequency-wise? i can find the S26's for $169/pair while the s36's are $239/pair... i don't think that extra midrange in the s36 is really worth $70 more?!?!
