Flat Anechoic Measured Frequency Response Speakers


No unverifiable claims please. No in-room response measurements please.

Please post link(s) to relevant measurements. They don't have to be perfect, but relatively flat would be best.

Thanks.

It makes sense that a flat frequency response is a good starting point. I don't know if people will inherently like it better without training. I can't even do that kind of experiment on myself, because I've done the Moulton Labs training courses...

It is very easy to take a flat frequency response and alter it after the fact by dropping dBs wherever it suits you if you find you would like to accentuate parts of the spectrum. My understanding is that it is much harder to fix a signal that is inherently flawed.
What do you think of the Moulton Labs 8 CD's and course? Do you think it is worth it for non audio professionals (8 CD's = $220 )....above all was it fun, a revelation?
Shadorne,

I liked it. It is cool to be able to understand when you are hearing things like ranges of the frequency response being out of proportion. Of course, with my 40-90Hz bass issues, I already knew there was a problem because of the kick drum from hell.

It is also nice to be able to identify compression, distortion artifacts, phase issues, reverb effects.

Some of the stuff, like effects, is fairly obvious if you play electric guitar (or other instruments where effects are used often), but others, like being able to single out areas of the frequency response when they are boosted, are pretty neat.
Shadorne,

In other words, I recommend it for anyone who is a fan of music. It can only help you appreciate music more by being able to discuss it with greater subtlety.

I would especially recommend it to you because the ATCs measure so flat. They would be perfect speakers for doing the coursework on.
