Looks decently made and has a nice integrated waveguide. Sadly, this is by far the worst soft done tweeter I have ever heard and measured. Despite being waveguided, there is a sudden rolloff at 10khz-20khz of 9db on axis which makes it impossible to design a crossover for. Resonant frequency is also 1.6khz, which is not even close to the advertised value. Waveguide is impossible to remove and reuse as everything is glued together.
Very good!
