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.

So if they or ASR wants to post frequency curves that's fine, neither will tell me what they measure in my room.  

@sunshdw Your speakers will dominate the measurements until the room starts to take over. If you have a larger room, the room will start to dominate the response at around 500hz....for a small room it's around 250hz...

However, if you have a very small room or speakers very close to sidewalls for example, you're going to end up with phase cancellations or peaks at much higher frequencies. 

Lets say a speaker has a 5dB frequency response error due to a rising response...and then your small room is reinforcing that peak another 5dB...at that point a 10dB peak in the mids or higher frequencies will make the speaker unlistenable...this is a core argument for mitigating frequency response errors at the factory.  

@bigkidz if you manufacturer hi-fi components...you would notice if the response of an active component was +/- 3dB. Having said that, I have never heard of a component that creates such large frequency response errors....maybe a tube amp with a very low damping factor trying to drive Magnepans would create some big response errors. ;-) 

For what reason?  Are you going to buy because of the chart?

Great question @bigkidz ....The chart is more likely to cause me to avoid a particular speaker. If for example the speaker has a rising response due to lack of baffle step compensation....that's not for me. I know that speaker will sound too forward and possibly even shouty.

So,  what is important about the Tekton review not having Eric's prior approval?  Is he a special case?

@mlsstl Yes, Eric is a special case in that it has become a pubic dispute and gives us an inside look about what normally goes on behind the scenes with reviewers and manufacturers. When normal protocols go away, we see what can happen. 

With Erin & Amir's ability to receive gear from subscribers, it puts the hi-fi industry on notice. Small boutique brands can potentially be destroyed. 

@mlsstl I am fully aware of the dispute...and I didn't feel the need to weigh in on Eric's behavior...that drama doesn't interest me. 

Both times you have called my @ handle, you are assuming things I didn't say...I believe this is called the "straw man fallacy." Or possibly a reading comprehension issue? You also were impolite so back at you ;-)  

@mlsstl permission is the norm so a review done without permission was worth mentioning for contextual reasons...no other implications.   

it sounds like you are trying to justify rude forum behavior. Just treat it like real life...you know the place that's not so safe if you provoke another male ;-)  

@mlsstl in this specific case Erin did notify Eric that he was reviewing his product, to make sure he had the correct listening axis. However, he didn't have Eric's permission to review his product or publish measurements....which is the norm for print media and YouTubers who have enough subscribers to be sent product. 

ASR normally doesn't have permission to publish measurements and Amir is the biggest exception to the norm.

Other companies have reacted similar to Eric in that they have threatened litigation. You don't have to go back as far as Bose v Consumer Reports. However, Erin leaked the information and put Eric on blast...that is uncommon. 

 

@botrytis I know this and even stated this. Please see my statement below.

in this specific case Erin did notify Eric that he was reviewing his product, to make sure he had the correct listening axis.

@mlsstl I didn't use the words "needing permission." You did...creating a strawman argument.

I wrote "didn't have permission" which is a fact and not a value judgement.
