It works in my old Mackie, but if it gets too loud with even coming close to lets say 34;half way34; in terms of the bass adjustment... it starts popping bad.

I liked the ease of installation of this speaker to a cabinet purchased in 1973. I am glad to know that I can find replacement speakers if needed in the future.

Whenever you need a very good top-end speaker for your music system, this is the speaker to have. The voice quality is superb. Just make sure that your top-end power amps is of good quality (e.g Crown power amps) to deliver the quality sound.
