Building my own monitors.

I've been fairly curious quite how much you can mask the inherent weaknesses of a speaker or a room with an EQ curve. Steve rated the JBLs from the rooftops at how much difference they made.

But whats stopping you taking a midrange hifi cabinet, and just tweaking it into a machine of precision excellence through the simple overlaying of a compensatinv EQ setting?

I looked at soundsystem design for ages. Building big rig speakers isn't that difficult if you are a half decent cabinet maker and can follow insructions.

Some lovely plans for big PA speakers. Mate of ours down in brighton has loads of "loony bins" and they siiiiiing. Beautiful precise warm bass, just a joy to listen to. Rate them much higher than F1 stuff personally. More character and less fussy.

There's probably some advantages of producing on a well set up engineered PA rig. You'll no doubt make tracks that tick all the boxes in a club, but might lack the detail you need to provide for the headphone listening crew.

Good luck anyways mate, you've set yourself a real challenge and sure you'll have fun and learn a stinkload.

Most Room Correction algorhythms deal with standing waves, and generally the cut (or at least hopefully, unless your room is ****ed) is subtle and at one point.
Other stuff deals with stereo balance and slapback etc
As a whole, RMC measuring and compensating for the room, not the speaker.
So the speaker still needs to be matched to the Program, or assumed to be a flat response speaker.

If you are building or ending up with a woeful speaker and box, that requires all sorts of EQ curving at mid and high frequencies, then you have earned an epic fail.
There isn`t any room correction that will compensate that much, and also, the more EQ you add to any signal, the more you are effectively adding distortion.
So you really don`t want to be adding EQ to the more delicate frequencies.

This shows exactly one of the many many intricacies of studio monitor design.

Making a rig is much much easier, unless you are looking at the real cutting edge stuff like The new Court Accoustics System, or the New Void System.
Speakerplans is a great place for soundsystem plans, and although fiddly in some places building a rig requires a lot less accuracy than nearfields.
Unless of course, you wanna make a real super beeauty of a beast of a rig.
