What if a high end speaker measures really badly?


You know, it's true that I feel listening is more important than measurements and that it's generally difficult to really tie together measurements with pleasure.  Below 0.05% THD do I care?  No I do not.  I really don't care. The number tells me nothing about whether I'd like the amp more or not anymore.

In this one memorable review for the Alta Audio Adam speaker, I really felt shivers go up my spine when I looked at the measurements, especially at ~$20kUSD.   This looks like an absolute hot mess.  Does it sound this bad though?  I certainly don't have the $20K to test that out myself. What do you all think?

Everyone should own a pair of L-100 at some point in life…. and of course the much better L-110

Actually, the studio version of the L100 was made to try to replicate the sound of the Altec 604 of the day.

I find people that don’t think measurements matter just lack experience. Use REW (it is free!) and start making your own correlations. 
 

I have had/have 4 speakers that have full kipple measurements posted publicly. I find frequency response and dispersion to transfer very well from measurements to my room.  
 

what I think is still missing in measurements is detail and transient response. The ability of the driver to start and stop with no over hang or over shoot. 

Some bumps are good and others not so much.

With DSP, you get to add bumps where needed and where you want them to be, not where they just happened to be when the product shipped.

I find with most speakers I tend to like a bump from ~4-6khz. That adds a bit of edge and definition, much like one might expect with a very good pair of high efficiency horns. In particular it helps to keep your attention at lower volumes. The other tweaks I might apply often tend to be more room and listening position dependent.

 

In the chart in the original post, that relative peak at ~10k in conjunction with the dip just below will likely result in a piercing sound (more fatigue) that might only benefit in certain more extreme cases of hearing loss. Would not be for me most likely. though again it may be nothing that some smartly applied DSP couldn’t resolve. But even if so, better to not have to apply DSP to fix what appears to be a significant design flaw. Better to go with a more suitable design right out of the gate where any bumps perhaps might be better located and maybe even work in your favor in some cases. You decide! To me a good design is always preferrable.

I'm thinkin' someone switched out the real speaker graph for a recent DOW stock market graph!
