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?

I don’t think the measurements should be ignored completely when buying speakers, even if they sound good to your ears. Over time, and outside the showroom, any serious flaws might start to become apparent. Reviewing the impedance graph can be even more important in terms of matching with your amplifier. Comparing sensitivity and nominal impedance only can result in a mismatch if there are some dips that your amplifier is not equipped to handle. 
 

A lot of high end speakers measure like poopy and a lot more sound like worse than poopy!

don’t buy that one easy!

use your ears and get in your CAR AND DRIVE TO AN AUTHORIZED DEALER NOT JUST SOME STUPID HOTEL ROOM SHOW AND HEAR DIFFERENT ONES!

I think the up/down peak/dip jogs are artifacts of the enclosure design, which is apparently a transmission line/port hybrid. 

 

@audiokinesis Ahhh! Thank you, I missed that in the article.  That explains why they posted the inner design of the 2-way as well.

A speaker can sound very good yet have a significant dip (or more than one). Generally that dip is at the bottom and most people check for that by playing songs heavy in bass. But a dip at a different frequency might not be caught until you play that one song that has an important note at that frequency and you say "what happened to that chord?"

Then you know something is missing and can’t enjoy the speakers any more. I do like to see a graph or a published number. Here are the numbers from my speakers: 20 – 20000 [Hz] ±3 [dB]

Looking at the graph for this speaker, it looks like the numbers would be 20-20,000 hz, +4/-8 dB. I think that would raise some eyebrows.

PS Everyone says "listen to these before you buy. My point is you may not catch these dips in a 15 minute audition.
