I have just finished my set of your 2,5way CA18RNX + 27TDC loudspeaker.
It took me almost one and a half year to finish, but you know what they say; better late than never!
They sound great with my 60W tube amplifier, but I think that a little more powerfull amplifier would make them sound even better.
I would like to say thanks for this magnificent website, I check in several times a week to stay updated on your projects and I find it great fun!
Here's a few photos from the building process, crossover and finished speaker.
Sincerely, Jostein, Norway
