Correction

We mistakenly ran identical measurement graphs for Figs. 2A and 3A in the test bench section of Thomas J. Norton’s Aperion

Audio Novus 5.0.2 speaker system review on page 64 of the February/march 2020 issue. The correct graph for Fig. 2A (the response of the left and right Novus towers with no subwoofers engaged) is reproduced below.
