If It Ain't Broke, Don't Fix It

I apologize,  I misspoke. The measurements pointing out the phase interaction where the tweeter and woofer were measured independently was done by Danny. Amir did not measure drivers individually. Since they were on his video and he was questioning what was even wrong with the measurements to warrant an upgrade, I assumed they were his measurements.

A lot of you guys that have been on here for a long time know me.  I was GM at Marcof Electronics and SpeakerCraft out of Webster Groves/St. Louis mo.  Retiring, decided to do similar work that GR does.  My new business concentrates on Speaker Upgrades and Repairs.  I saw Danny’s original video and I saw the ASR post.  2 things,  lowering the ribbon to 2.5k could have added a little distortion, without measuring, I’m not sure it was enough to cause the problems that Amir maintains, but I doubt that it would be as bad as he states.  second thing.  The waterfall that Danny showed was a dramatic improvement. Nor did Amir mention cabinet resonance improvements. I have no doubt that overall this speaker sounded better... Lastly, the parts improvement do improve focus, imaging and soundstage that ASR really did not check at all.  I hope this helps in some way,  Tim..... I am now Speaker Upgrades  dot com

Amir was a senior executive overseeing codec and media technology development at Microsoft.  He  oversaw the development of successful audio and media codecs.  They employed standard scientific protocol for developing codecs - eg double blind testing.

Then why doesn't he do this method he's been trained on? He advocates blind testing but doesn't do it for confirmation. Not a listen!!  To make such a claim that could damage a persons reputation and business model I think I'd take a listen before throwing dirt. Danny could do the same.

I’ll wait for the AI summary, thanks.
