I don't want to jump to conclusions, but i would like to tell you, that all my Concrta speakers (F12,C12,M12) were from Mexico ( as we know, it was intended to reduce the price point) but i bought them 1,5-2 years ago.
A few weeks ago, i bought a used Concerta b120 sub ( as i told you here already) which was 6 months old, and I was very disapointed to see on the box, that it was made in China
I mean we are talking about a sub retailing for 1000$...
It could be, that the higher lines (Ultima/Performa) are produced now in Mexico, and the in-wall, and Concerta lines are made in China. I hope they won't push the Performas to china as well... It would be such a shame
