I don't know how to interpret the clarity measurements but here are mine. Please note that I took another measurement for the decay and waterfall plots because I had higher ringing ~120Hz that reduced 3-4dB the second time.
Bass decay shows impulse, 140 and 160ms, waterfall shows about 30dB on y-axis, full spl is variable smoothing, bass spl is no smoothing, impulse response envelope and clarity graphs are what they are. I only measured from 27Hz because that's A0 in musical terms and my sub doesn't play with accuracy to that range anyway.
This is post-EQ from 18 measurments around my listening position, nine in a grid then nine more at seated height, averaged then placed into EqualizerAPO. Speakers are Yamaha HS50 with HS10w subwoofer (quoted -10dB @ 30Hz) @ ~1m with a calculated level from REW of 74.4dB in a treated space of ~2500ft3 and irregular shape.
How does my bass sound? I take you to mean with the mains because without them it sounds just like a subwoofer. It sounds spacious, accurate and flat, slightly elevated but not overwhelming. My taste is not to have a ton of bass so it's fine. This calibration is for music creation more than enjoyment and a similar calibration I used before this worked well, allowing me to achieve the "translation" that audio people chase, as least in the low end. My plan is to swap out my mains when I can.
Let me note that 120Hz is a problem frequency for me right now. I had to use the high pass filters on my mains to 80Hz to get the most even response at that range. I tried 100Hz and inverting the subwoofer's polarity but none of that worked. Quarter wavelength is around 2' so I think it's either a desk bounce and/or a front wall reflection; I have no absorption behind the speakers except for two floor-to-ceiling 32"-wide fluffy superchunks in the corners. If I look at the minimum phase generation, I'm pretty sure it's not flat right there either. As far as I know, that means EQ is less effective there and that could be why there's more decay.
