My question is, should I EQ each sub individually, then EQ them together. Or should I EQ the combined SPL readings
Local wisdom claims it's best to equalize two subs together as if they were one...........

I will be designing a hard knee house curve for my EQing based on Wayne's article
Figuring out a 'hard knee' is no longer required. The latest version of REW allows logarithmic interpolation for house curves. A checkbox is provided for that function. Wayne will have to modify his info.

I doubt anyone’s going to miss all the trial and error that’s required to come up with the proper .txt file!

Now the only challenge is how to say “logarithmic interpolation” without getting tongue-tied...

Re: EqualizingTwo Subs

Thanks Guys
I'm going to have a go this weekend.

BTW, I developed a hard knee house curve (for practice) by printing the default curve. On the print I drew the straight line I wanted. As the vertical scale is linear, I just measured the vertical gap between the curve and my straight line, adjusting the measurement to dB using, say 10dB on the axis as a reference. I had to add more lines to the frequency scale between 30 and 50 Hz. That's a bit more difficult, but not impossible. My resultant txt file gave me a near perfect straight line first up.
