Is that a typo? I'm sure it was more than 300 hours, but I thought it would be much more than that.
Full quote:
"Through 2018 and into the spring of 2019 the diamond tweeter was optimized for better performance in the 1-40 kHz frequency range and with improvements in the production processes as well, for higher linear excursion (FEA optimized suspension, verified by measurements) with lower distortion at low frequencies, smoother response and better batch-to-batch consistency.
To facilitate this development, SEAS has invested more than 300 hours of engineering, as well as a new Brüel & Kjær NEXUS conditioning preamplifier which is linear to above 100 kHz, and a Benchmark AHB2 analog power amplifier with low distortion and low noise well beyond 100 kHz, such that the entire measurement chain is geared towards high-res and high-frequency audio measurements."
I think what they mean is that they invested 300 hours in just the past year (2018-2019) in making performance improvements to the original design.
