[QUOTE="John Halliburton, post: 33558, member: 8"] Re: McCauley M421 Quad 21" Subwoofer Paul, While I don't doubt the M421 is a good sub, McCauley suffers from the same issue you point out in your post-they don't relate the -3db to any reference. Also, they want to annoy us with a 4m ground plane reference. They also don't publish any response/impedance/phase curves, so I honestly don't know if this cabinet will do as it says. Has Pat Brown measured one possibly? Ivan, weren't you going to get a bunch of subs together and measure them under the same conditions-assuming you will get some free time? Best regards, John [/QUOTE]
