So many ear based audiophiles will hate this...

A masterclass on speaker measurements Amir. Kudos! The knowledge just flows out so naturally from your mouth that it shows how well you understand the subject. Thank you for sharing that knowledge and passion.

How about ya measure your ears!

Amir's speaker measurements (more than a dozen and counting) have lined up with my listening impressions. Accurate results; and he is doing these measurements properly. Even using the best high-end amplifiers and source components will not correct a bad pair of speakers. Instead, top-notch gear will only spotlight the shortcomings.

I knew all this already because I actually have read Tool's book but I still immensely enjoy listening to Amir explaining this stuff as comprehensively as he does.

I don't understand there are many many many many speakers out there that measure poorly and the get rave reviews.....In my experience speakers they all sound different in every room.

You going about the 2K 3K but what about the BBC dip where they say it's better to have these frequencies at a lower DB for more natural sounding speaker You're not particularly agreeing with that scenario why!? Yeah and I didn't add the other frequencies because we're not talking about that

Hi this is Poolio from Belgium. You are a hero of mine. However I am having trouble getting people to believe my scatological audio information. I even start out by saying I am from some exotic location, and even throw in something obscure about the weather to lend credibility. Sadly they still don't believe my serpentine essence. What am I doing wrong? Am I too tranparent?

Music is fun with good equipment, then there is all kinds of stuff around. Most of it can be fun? For a while?

You have brought a lot of truth to this area. The snake oil pushers are in trouble when faced with the reality of measurements.

Great tutorial! Very important.

Wow, this was everything a person could want to learn from speaker measurements.

The waterfall explanation, and actual worth of it, was a great eye-opener as many reviewers use this as some sort of bible. Again a very meaningful, understandable and entertaining course with a touch of humor. Appreciated!

Very thorough explanation of direct vs early, vs effective power "in room" response in a room. Excellent discussion of the challenges getting test gear to reveal real aberrations of the speaker, vs mic location(s), or room contribution. I envy your test platform!

You know someone knows by the clarity of thought (mentally seeing clearly the concepts) and holistic grasp of the subject. Roads traveled which aren't worth taking, etc.

Very nice! I've never struggled to read the graphs, but the explanation of the physical causes of various deviations from ideal is the sort of thing that takes many years of experience to develop an intuition.

I took a leap of faith and blind bought some used Revel 106’s at a great price to replace my B&W CM5’s. The B&W measure to have that happy FR showroom sound (measured by Stereophile, and confirmed by Dirac Live to behave as such in my listening space) that wowed me when I bought them from Best But Magnolia 12 years ago. The research on preferences did not lie to my ears, and I do very much prefer the neutral and well-behaving speaker. It sounds great at all volumes and with all genres of music, which I couldn’t say the same about the B&W.

What a really good tutorial and it does open up a whole set of other questions. Hopefully there are more explanations where these came from. Look forward to when they come along.

Thank you for this demonstration, in particular on the interest of well controlling the dispersion pattern of each driver under different listening angles, I learned some things important for my future 4-way DIY speaker project ! My listening room is not very big but it opens on both sides to other rooms, which lengthens the path of the reflected waves. I use a professional DSP based on the SHARC ADSP21489 (not a MiniDSP) 4 inputs and 8 outputs on XLR on my Magnepan 1.7i active, Purifi amplification and Viawave supertweeters to make up for the lack of air.

FANTASTIC!!!!! Thank you very much! Best audiophile video and most informative audiophile video I’ve ever seen.
