I was reading the April 06 Boys Life with my Tiger Cub when we ran across an article that described extinguishing a candle with a 120 db 55 hz tone. Since that is not something to pass up we donned ear protection and gave it a try. I ran a disc with tones 5 hz apart starting at 20 with no luck. We should have measured with the spl - but didn't so I don't know how close to 120 we got. We did manage to blow out the candle when we put it right in front of the sub with the grill removed (it went out about 35 hz). Can anyone out there get at least 120 db at 55 hz? If so I would love to hear the results.
