Recently replaced 2 Klipsch R-115SW with 4 Rythmik FV18. Gain matched them by REW/UMIK1/SPL measurements all in the same location. Set gain offsets in minidsp.
Then followed general process outlined here to incrementally add all the subs to ensure that each addition resulted in net positive SPL:
Here are my measured results:
Equalized/flattened the response to 76db in REW, imported into minidsp PEQ, results (top line is unequalized full 4subs, bottom is equalized):
Ran ARC and followed steps here to ensure a good house curve and that the final eq'd curves hug the target curves as much as possible:
ARC file after getting audio measurements and before I did any fiddling:
rythmik_initial_setup_post_audio_measurements_before_adjustments.arc3
Adjusted/final ARC file:
rythmik_fully_adjusted.arc3
End result is that new subs sound less boomy/bassy than old subs in exact same room - very "meh". I didn't do any measuring/empirical testing with the old subs when I put them in 5 years ago - just kind of subcrawled a bit and then fiddled with phases until I got something pleasing-ish.
Can anyone spot what I've done wrong? It seems like "on paper" with the empirical tests I've done I should be getting great results, but I don't yet understand.
Another strange thing is that the frequency sweep graphs in ARC for the subs don't look like my REW frequency sweep graphs. Can anyone explain that? My fronts are Founder 120Hs - do their frequency graphs look correct? They seem to have this huge 94db cliff from 30-50hz and then tapers down to around 75db by around 100hz and then stays there. I'm not sure if that's normal.
Thanks for any assistance anyone can provide!
