From a greater distance, smaller values of C(D) can be measured (and heard), down to an inarticulate bass in ordinary rooms@ ~1m.. in a treated space of ~2500ft3
Thanks for your response. Can you point me to a good resource on understanding these Clarity graphs? The REW help says it’s the ratio between direct and ? sound in dB but I’m not sure if lower or higher is more “clear” and why the lines would not be horizontal whether they should conform to a certain shape or what importance wiggles in the lines have.

Thanks for this. I'll check out MATT and review this thread. Cheers.I think there is some discussion in this thread. As a metric of the quality of bass reproduction, these indicators are not generally accepted and are quite rough.
See also discussions about MATT test aka Stereophile Test disk 2 track #11.
Ideally, the D50 graph line is approximately horizontal between 99% and 100%
BTW here's an ordinary sound card:

Clarity looks very good. I don't know if it would sound better to damp it down further or not. You'd have to try it and decide. Your room clarity looks very similar to mine, except yours is better below 200 Hz. I think my room sounds really good above 200Hz so I'm not inclined to add more absorption. I had some Revel M16 at one time in this room and they made the room sound overdamped. Not sure why, but my current setup that's all horns doesn't come across that way. I percieve it as more lively even though it has a considerably higher directivity index. So, I think it's hard to say exactly where that RT60 should be. Cn you include the RT60 too? Just curious to see it. Mine hovers around 280ms except in the bass, where it gets up to 600.My Setup consists of Revel F226Be, x2 Rythmik E15s, Benchmark AHB2 & DAC3L, SMSL PO100, I7 laptop running Audirvana upscaled x2,x4 to 176/192 VST3 HLC, EQ and phase adjustments with REW and Rephase with convolution filter. Semi treated medium sized open basement living area located in unsymmetrical part of the room approximately 9 feet from speaker to MLP, 27'Wx14'Lx7'10"C opens up to more to sides of listening area, Rspkr 6' from right wall. Have a serious ~60hz dip on right channel. Looking for any comments - RT60 is definitely not as good as some here, may need more treatment (RT60 350) and the upward tilt >10k is intentional, EQ 10hz-6k boos<3db and rephased closer to flat >200hz. Probably more than necessary info. Curious if any thoughts on my measurements or improvement ideas. Sounds great, better than my Arya hps, really tight imaging vertically and horizontally, good texture in the bass and clear but I am discovering that until you hear it you just don't know how good it can get. Measurements are both speakers and subs.View attachment 371145 View attachment 371136can always learn something.

Thanks for the feedback. Attached is my RT60 which sounds like it is much higher than your RT60. Mostly in the 400s and in bass gets quite high.Clarity looks very good.

It is interesting that you've got such a very flat response from 200Hz on up. My latest settings have me at a 1 dB/ octave slope at the listening position, which is surprising to me but sounds good. I've had some very flat response in recent times. This occured more by accident than intentional, as a result of crossover settings. It was intriguing in some ways but overall too bright for me.
That is interesting. You've got good clarity despite a higher RT60 time, especially between about 600 Hz and 2 kHz. I imagine that probably sounds really nice! Without seeing further detail, I'm guessing the initial sound is relatively loud compared to the reverb tail. So even though there's a longer reverb time, it doesn't dominate the direct sound enough to murk it up.Thanks for the feedback. Attached is my RT60 which sounds like it is much higher than your RT60.

View attachment 371596I think running Rephase adjusting for crossovers and making the speaker to speaker phase flattish and <+/-15 degrees apart 200hz up helped clarity a bit. The flat frequency response was intentional although I may add some slope. My hearing isn't what it used to be. Need to rerun EQ etc. and do some comparisons. Look forward to any thoughts you may have.
