Schu Posted April 12, 2020 Share Posted April 12, 2020 Possibly... if that's where they are on modern pieces. I didn't open up the bass bins. I don't see why they would be. You notice also that klipsch made a tiny change from the original ak4 (top) to the most current version ak4 (bottom)... The photos are just for reference...
