Anthony,
As you know I'm not keen on any room EQ, but I don't object to using it in the lowest octave or so, maybe up to 50 or even 60 Hz, where bass traps are less effective. But I'd never use EQ above the low bass range.
As for products, any modern fully parametric EQ should do a fine job. But the only way to set it properly is to measure at high resolution using something like the ETF and R+D software.
