replacement for the Tangent EVO E4’s?

Yes, new BRI work largely lab based all week, but a local lab map has been made and some of the team out testing the new amp’s range. It’s fine. Funnily enough, Seppo on Hailuoto specced this back in 2013, but we used a Kenwood car amp, and Monse independently found it and we used it in Houston in 2014. Electronics world also so small? We wish the speaker world was larger. Serious struggle trying to find a replacement to the Tangent EVO E4’s( no longer made) Any ideas anyone? please post us, thanks.
