Re: McCauley M421 Quad 21" SubwooferPaul,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

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.

Best regards,
