[QUOTE="Paul Bell, post: 33094, member: 413"] Re: McCauley M421 Quad 21" Subwoofer Friends, Forgive me if I haven’t been active on this forum, I’m starting to get a bit overwhelmed by the various internet forums I’ve become associated with. As many of you know, I’m a regular user of McCauley products, with some pretty good results. When I’m not happy with something, you can bet I say/do something. I do have a set of cabinets with custom horns I had made. So don’t assume I’m gonna automatically go to bat for McCauley. When dealing with pro speakers of this level, it’s never wise to assume the manufacturers specs/claims to be dead on. You audition a speaker. You add the factory recommended EQ. You test and see it’s response. You add some EQ of your own. I don’t think there’s a pro speaker on the market that’s dead nuts on what it’s maker says it’ll do. Self powered speakers would be the exception as they're usually thoroughly tweaked by it's maker. Example: The widely used JBL SRX728. JBL says it’ll do 33Hz at -3db. Compared to what? At 33Hz, it’s down 8db from what it does at 50Hz. Regardless of what any cabinet is and what it’s maker says it will do, us here in the business of “pro sound and production” will test a cabinet with some level of precision and add in our own flavor of equalization to suit our needs and tastes. This speaker is certainly not the first one to not exactly match what it’s maker’s specifications say it will do. Nor will it be the last. My take on the McCauley M421: As it has this peak at 65Hz or so, obviously it’s a result of it being partially a horn loaded sub. As it easily goes down to 30Hz real loud without EQ boost, it is a substantial subwoofer. Looking at my friend Mr. Prescott’s un-equalized response in post number seven, I’ve extrapolated at 25Hz it’s down about 7db from it’s output at 31.5 Hz. If you REALLY need sub energy down that low, give it about a 6db boost, HPF it no higher than 20Hz and you should be good to go. If you hate that punchy horn hit, cut a bit centered around 65Hz. Now with this EQ setup and the sheer power capabilities of this cabinet, how will it perform? Can you honestly say there’s ANY other cabinet that’ll do what this one does? This is certainly not a cabinet I could use in my productions. If I owned a huge rig and often did events on the level of Madison Square Garden, I would own and have use for these subs. I know there are several touring level companies that are using them with great success. [/QUOTE]
