I've been quite impressed with my M2OW. I've been thinking about how much better exactly are the active LFR1100s over the M2OW.

I've figured they are 2 times better. Here's how.

An M2OW, ADA1250-2, EP175 system costs $3845 Can. It can reach as low as the active LFRs but can "only" hit a max of 116 dB SPL at 3 feet away.

An active LFR1100, 2xADA1250-5 system costs $17,715. It can hit a max of 129 dB SPL at 3 feet away.

129 dB is 13 dB more than 116 dB. Every 10 dB of sound pressure is perceived as twice as loud. Close enough.

So there you have it. The active LFR1100s are two times better than the M2OW but cost almost five times as much. Loudness costs!
