The Eficion F300 is a premium floor-standing loudspeaker designed with a 3-way, 4-driver ported enclosure. It includes a 2.3" x 0.3" ribbon super tweeter, a 5.1" x 1.4" air motion transformer tweeter, a 6.5" carbon fiber midrange driver, and a 12" carbon fiber woofer. The speaker offers a frequency response from 25 Hz to 40 kHz and a sensitivity of 89 dB at 2.83V/1m with a nominal impedance of 8 Ohms. The crossover frequencies are set at 110 Hz and 1.3 kHz. The design features a two-piece construction with a large woofer enclosure and a separate top section housing the midrange and tweeters, allowing for precise sound staging and clarity. The cabinet is finished in a high-quality black lacquer and weighs approximately 158 pounds per speaker. The Optimal performance requires careful positioning and pairing with a fast amplifier capable of controlling substantial bass output. The F300 is noted for extraordinary detail, clarity, air, and extension in sound reproduction.
