Tbg- it's been repeatedly shown that mdf is poorer to other materials. I'm sure JA's measurements on a Tidal will clarify that as well at some point in the future.
But considering the price Tidal charges (24k for a 2.5 way and on up)--- I personally expect more. Magico's V2 has a better cabinet at 30% less (both 2.5 ways).
I'm sure the Tidals sound good---but my guess is that yet another mdf speaker with ceramic drivers won't make a push like Magico into the upper echelon. Perhaps i will be wrong, who knows.
