Should Speaker Manufactures provide a Frequency Response Graph?


Eric at Tekton Designs has been battling two different reviewers who have posted measurements without his permission, using Klippel devices for their respective measurements.

It seems to me that if manufactures provide a simple smoothed out graph, consumers can see how much a speaker is editorializing with a frequency response that deviates from neutral.

MAYBE some people may like the sound of the speaker regardless of the graph. MAYBE it does sound good even with a not so perfect graph. MAYBE it's thinking outside the box and creating a speaker that has it's own unique signature. 

ThomasAndStereo does NOT post any negative reviews. If it doesn't sound good to him he just sends it back. 

This way the company won't get the benefit of a positive review and they also won't get slammed negatively in an open forum that could have serious impact on their business. Could even put them out of business on the opinion of ONE bad review.

 "If you don't have anything good to say, don't say anything at all" because YOU might be completely wrong!

 

Nope.  I buy speakers based on my hearing, not a graph made in a testing lab.  

You are gonna stare at a Frequency Response graph and not know a whole lot. Manufacturers should provide a minimum of the following:

Frequency Response

Impedance

Sound Power

Impedance

Directivity

Dispersion Polar

Waterfall Plot

7 plots...should be able to take it from there...

Posting a graph wouldn't be bad idea.  I'm sure some would resist, especially those with poor graphs.  I think if we had them all, Tekton would fall toward the top.  Eric has always been proud of his flat frequency resonse.  

They already post numbers like "40-23000 Hz +/-2 dB" so show us the graph.

I agree, buy speakers based on how they sound but as a physicist, I would likely use graphs to choose which ones to check out.  I certainly would have a problem with one that had a big dip in middle C, for example.

I think those who are having fun criticizing Tekton would not really want to see a graph of their own speakers.
