The -3dB cut off frequency which indicates equal reference volume output begins at 55Hz, as opposed to 35Hz in the Eminence drivers, and emerges in a peak to 100Hz and declines to 160Hz. Below the Power Handling is diminished (in red) to a low of 236 watts @ 65Hz. So at 65Hz, the 1801 8 ohm in a 6 cubic foot cabinet tuned to 35Hz is a 236 watt speaker, even though the rating is 350 watts rms. |
