I finished watching Toole's video earlier today. He was waxing poetic about Harman speakers and showing off the curves of one. The listening window and sound power were at least 3dB apart and the listening window was flat. These apparently were state of the art and as good as it can possibly get. They looked worse than the M5 actually. That M5 is probably as good as any passive speaker can possibly get. Enter the active LFRs with aligned, declining curves and that should make everyone out there take note and question what the hell they've done for the audio world lately.

He also totally trashed Martin Logan. Their curves looked like the Rockies.
