The JBL Pro 4641 is equipped with a 46 cm (18") woofer, specifically developed by JBL to reproduce very low frequencies. Its preferred frequency range precisely matches the Dolby or DTS specifications for the low-frequency channel of multichannel audio tracks, from 20 Hz to 150 Hz.

JBL Pro 4641: Dreamy max SPL

The JBL Pro 4641 subwoofer boasts a sensitivity of 97 dB for 1 W at 1 m, measured at 100 Hz. This exceptionally high value is due to the very powerful moving assembly of the JBL 2241H driver.

The bass-reflex enclosure is tuned to 25 Hz, and the subwoofer responds down to 35 Hz with only 3 dB of attenuation. To linearize its response down to 20 Hz, the use of a power amplifier with active equalization can be considered.
