Affordable vs. ultra expensive speakers - what's the difference?

Even great and frugal engineering talent like Jim T have to deal with inflation. The 2.4 cabinet performs poorly against some of its more modern competitors which as they are still in business subject to inflationary pressures. A study on beating inflation are the Vandy model 1 and 2. No flames please, I am a Thiel fan and until very recently owned a pair of 2.3 +

Is a there a link to point to a test that compares the cabinet resonance?  I am not aware of any specific test.

Well put. Value is highly dependent on many things.

Only working a few years in 1979, I took out my first loan to buy the state of the art… Pass designed Threshold s500 for $5000. The average car back then cost $6,000). That amp in todays dollars is ~ $19,000. 

I haven't seen any measurements on YG other than some back in 2013 on Stereophile and those were nothing to get excited about. If you want aluminum I'd take a pair Genelec 8361a for $10k with GLM and adjust to my room. For another $16k toss in the W371A and I'd be at my end game.
