You should run them through a mode calculator such as these:

Is not a high ROI path.
I'll just have to save up for some MiniDSP magic and a good ADC - in the medium term.
Much else to do - once I am well - xxxxx fingers.

The software is free. The subs need to be in mono for this technique to work though. The idea is to get flat response at multiple listening positions simultaneously. You make a bunch of measurements in Room EQ Wizard, export them as text files and import them into the program. After some setup and running an optimization, it calculates the filter coefficients to load into the miniDSP to optimize performance.

I don't know of any spreadsheet / Calculator for L-shaped rooms.
Does anybody?
Or is there a way to overlay L-shaped room dimensions onto / into those calculators?

1. I agree that using electromechanical as opposed to software filtering is like going back to using hand-tools.
2. There are modelling programs for non-rectangular rooms. I no longer used them because, today, one can actually measure the modes more easily than one can analyze and predict them. So, I have used CARA 2.0 in the past but, now, I just measure with REW or DiracLive Calibration.
