@reaper81 I’ve built speakers with exciters before, and the only way I found to really get nice treble was to use a tweeter in addition to the exciter. You need a crossover so the tweeters don’t blow if you crank the volume. I would say if you got tweeters you could point them up and hide them behind the mirror? This mirror build is very nicely done!

Here is a link to my exciter speaker build for the curious. https://www.youtube.com/watch?v=D6hGmyNImaI
