Between January and April of 2014, I began designing and building my own pair of studio monitors. The end result was a pair of monitors that are +/- 1.5 between the frequencies of 65 to 20,000 Hertz. Though depending on room size, they can accurately reach as far down as 35 Hz. Weighing at around 40 pounds, they are about 17 inches tall, 11.5 inches wide, and 14.5 inches deep. They use the Dayton Audio RS-225 8" woofers and the Vifa NE19Vtt-04 3/4″ tweeters.
