Should Speaker Manufactures provide a Frequency Response Graph?

The full measurements that the kipples spit out are super valuable. At $100k-ish they don’t cost much for a business to own. It is a way for smaller (compared to Harman, Kef, etc) companies to do measurements and make better speakers. It is much cheaper than anechoic chambers which can be upwards of a million dollars. When companies want to sell speakers for $30k+ I expect them to invents money and time into design equipment. 

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

This! I agree completely.

"The full measurements that the kipples spit out are super valuable. " In what way? Do these measurements tell me I will like what I hear? No! I am not an ASR minion that needs to be told whether a speaker sounds good or not.

The only figures I look are is the efficiency and the nominal impedance as they will give me an idea if my amplification will drive a speaker without any issues, then I just listen.

If graphs are important to you, check out Ascend Acoustics. They provided them and even included a copy of my specific pair of raal towers in the shipping box. That was more than 10 years ago. I even discussed it with the owner. They were just slightly off the one published, but even better. I no longer own these but have only good memories of them.

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