For only $85 each brand new shipped, I don't see any other speakers on the planet that can touch these speakers in terms of measurements (Soundstage/NRC).
Anechoic NRC:
5-point Avg +/- 15 degrees response is 70Hz-80kHz +3dB/-2dB; the +3dB is ~ 800Hz, otherwise it's +/-2dB; 65Hz @ -3dB.
Even @ 60 degrees off-axis, the polar response is down ~ -6dB @ 10kHz, -8dB @ 1.5kHz, otherwise -5dB from 650Hz-9kHz.
Of course, I might add that speaker measurements are not EVERYTHING. I believe that higher-end speakers will sound better. But for $85 brand new, it's hard to beat.
