VAUGHN LOUDSPEAKER LINE ARRAY REVIEW $9000 Review
April 22, 2023 §
I normally measure distortion using an 85dB signal across the bandwidth at my listening position, which would be about 94dB at one meter from the speaker. For the Line Array Majors, a 95dB signal at the listening position was used – a full 10dB above the normal test. This was loud enough that I wore earbuds for protection while taking the measurements. This is a slow sine wave, and not an enjoyable listen. It’s also a very difficult test for a speaker.
Let’s look at some distortion data from 80Hz and up. The black line is the frequency sweep, and the blue line is the THD+N. Any point with a 40 dB or greater spread between the lines is 1% THD or less. At 80-160Hz, we saw nothing higher than 1.47% THD. Above 160Hz, the THD was below 0.5%, hitting a low of 0.14% at 1,000Hz. This is an astonishing performance and dovetails perfectly with the listening results
