Tower Speaker Reviews

Highlights
• Relative ease of setup because of the Prodigy's ForceForward bass alignment
• Custom-designed CE-certified binding posts for easy torquing
• Expansive, deep, transparent soundstage

HT Labs Measures: MartinLogan Prodigy Speaker System

This graph shows the quasi-anechoic (employing close-miking of all woofers) frequency response of the Prodigy L/R (purple trace), Theater center (green trace), and Scenario 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.

On-axis response of the Prodigy L/R measures +1.73/-2.78 decibels from 200 hertz to 10 kilohertz. The -3dB point is at 37 Hz, and the -6dB point is at 33 Hz. Impedance reaches a minimum of 1.12 ohms at 20 kHz and a phase angle of -90.65 degrees at 14.2 kHz. Sensitivity averages 87 dB from 500 Hz to 2 kHz.

On-axis response of the Theater center measures +1.76/-2.49 dB from 200 Hz to 10 kHz. The -3dB point is at 76 Hz, and the -6dB point is at 66 Hz. Impedance reaches a minimum of 3.24 ohms at 132 Hz and a phase angle of -62.1 degrees at 93 Hz. Sensitivity averages 87.5 dB from 500 Hz to 2 kHz.

On-axis response of the Scenario surround measures +3.87/-9.35 dB from 200 Hz to 10 kHz. The -3dB point is at 322 Hz, and the -6dB point is at 52 Hz. Impedance reaches a minimum of 1.84 ohms at 20 kHz and a phase angle of -100.9 degrees at 16 kHz. Sensitivity averages 88 dB from 500 Hz to 2 kHz.—AJ
