[QUOTE="winkychevelle, post: 8811998, member: 611804"] It definitely has a rolled surround and a fairly heavy motor. The fs is like 37.5hz which is really low as well. Typically hpf should be 1.5x the fs of the speaker. That would be 55.75hz for the flutes. I usually cross them at 63hz. The only down side is the upper end frequency response. They start to get muddy above 2600hz. Most tweeters should be crossed in the 2800hz and up range which can make finding a complimentary tweeter difficult. 25mm hard domes usually cross above 3khz, 25mm silk can tolerate a little lower. 28mm silk is ideal, I'm gonna try dd 28mm ceramic domes next they should handle crossing at 2600hz just fine with the low 1700ish hz fs [/QUOTE]
