Hello, I am looking for people who have *in person* experienced a rotary woofer, or if there is anyone who knows anyone who has one in the Minnesota area; I realize this is a relatively rare item... I am in the beginning stages of researching to build one of my own and was wondering about a few things, particularly how much unwanted noise is produced by the fan blades? the
seem to have a lot of 'white noise'; presumably from the edge of the blade... I am thinking of ways this noise could be minimized, also I was thinking of making a shroud mechanism to also help reduce noise (think of a large diameter, short length, flared subwoofer port). Please give me your opinions and thoughts on the shroud idea and any ways of reducing the 'white noise' effect from the blades acting on the air; I was thinking that some sort of soft 'fluffy' attachment to the leading edge of the blade could help (think of a 'boa' like material, like what girls wrap around their necks, but very small diameter).
Thank you all for your input!
