Tower Speaker Reviews

• Mythos Four L/R Sensitivity: 87.5 dB from 500 Hz to 2 kHz

• Mythos Three Center Sensitivity: 89 dB from 500 Hz to 2 kHz

• Mythos Gem Surround Sensitivity: 87 dB from 500 Hz to 2 kHz

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

The Mythos Four's listening-window response (a five-point average of axial and +/–15-degree horizontal and vertical responses) measures +2.77/–1.26 dB from 200 Hz to 10 kHz. The –3dB point is at 104 Hz, and the –6dB point is at 90 Hz. Impedance reaches a minimum of 4.82 ohms at 267 Hz and a phase angle of –30.34 degrees at 162 Hz.

The Mythos Three's listening-window response measures +0.95/–2.91 dB from 200 Hz to 10 kHz. An average of axial and +/–15-degree horizontal responses measures +0.97/–2.98 dB from 200 Hz to 10 kHz. The –3dB point is at 122 Hz, and the –6dB point is at 106 Hz. Impedance reaches a minimum of 3.96 ohms at 251 Hz and a phase angle of –46.45 degrees at 158 Hz.

The Mythos Gem's listening-window response measures +1.52/–2.17 dB from 200 Hz to 10 kHz. The –3dB point is at 162 Hz, and the –6dB point is at 134 Hz. Impedance reaches a minimum of 4.68 ohms at 343 Hz and a phase angle of –51.06 degrees at 183 Hz.

The SuperCube II's close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 27 Hz and the –6dB point is at 25 Hz. The upper –3dB point is at 110 Hz when using the LFE input.—MJP
