I saw your room reponse check, thought you might want a more accurate
measurement. I have software that will help. You would have to redo the readings starting with adjusting db for one of the spkrs for reference @200hz,70db. Set the mic where the 2 spkrs cross (sweet spot). Measure/write all db, 20 - 10khz at this distance. Then measure db, 20-200 Hz near field (within 1/4" of center Woofer dust cover; will be ~30db higher) Aim the meter on a stand (diy.. 5/8" wood dowel rod screwed into plywd base, find 5/16" pan hd for mic screw; which is put thru std plastic 1/2 plumbing snub end, slide on a match male/female elbow fitting; this will slide onto dowel top.. no glue. Measure/cut dowel length for the center of Tw cone ht., cut another dowel for the center driver of your 3 woofer arrangement.) Send me the readings and I will send you a plot with a comparison to top of the line speaker using the same method. I am retired with time on my hands.
