This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Mythos ST L/R (purple trace), Mythos Eight center channel (green trace), and Mythos Gem XL surround (red trace). All passive loudspeakers were measured with grilles at a distance of 1 meter with a 2.83-volt input and scaled for display purposes.

The Mythos ST's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +1.28/–1.68 decibels from 200 hertz to 10 kilohertz. The –3-dB point is at 30 Hz, and the –6-dB point is at 26 Hz. Impedance reaches a minimum of 5.21 ohms at 356 Hz and a phase angle of –36.19 degrees at 179 Hz.

The Mythos Eight's listening-window response measures +2.18/–4.55 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +2.21/–4.88 dB from 200 Hz to 10 kHz. The –3-dB point is at 88 Hz, and the –6-dB point is at 66 Hz. Impedance reaches a minimum of 4.63 ohms at 247 Hz and a phase angle of –51.51 degrees at 139 Hz.

The Mythos Gem XL's listening-window response measures +6.06/–1.73 dB from 200 Hz to 10 kHz. The –3-dB point is at 120 Hz, and the –6-dB point is at 106 Hz. Impedance reaches a minimum of 3.98 ohms at 288 Hz and a phase angle of –49.63 degrees at 158 Hz.—MJP
