Unpacking the Subwoofer

If you suspect damage from transit, report it immediately to your dealer. Keep the shipping carton and packing materials for future use.

PLACEMENT

Since the installation of a subwoofer can be somewhat more complicated than installation of full-range speakers, it is essential that you read this section very carefully prior to connecting the subwoofer to your system. Should you have questions relating to your installation, it is advisable to call your dealer or distributor for advice.

The performance of the subwoofer is directly related to its placement in the listening room and how you align the subwoofer with its satellite speakers. Setting the volume of the subwoofer in relationship to the left and right speakers is also of critical importance because it is essential that the subwoofer integrate smoothly with the entire system. Setting the subwoofer’s volume level too high will result in overpowering, boomy bass. Setting the volume level too low will negate the benefits of the subwoofer.

Here are several additional facts on installation that may prove useful.

It is generally believed by most audio authorities that low frequencies (below 125Hz) are nondirectional and, therefore, placement of a subwoofer within any listening room is not critical. While in theory it is true that the larger wave- lengths of extremely low frequencies are basically nondirectional, the fact

is that, when installing a subwoofer within the limited confines of a room, reflections, standing waves and absorptions generated within the room will strongly influence the performance of any subwoofer system. As a result, specific location of the subwoofer becomes important, and we strongly recom- mend that you experiment with placement before choosing a final location.

Placement will depend upon your room and the amount and quality of bass required (for example, whether or not your room permits placement of the subwoofer near either satellite).

With its sleek design and robust performance, it provides deep, resonant bass that can enhance music, movies, and gaming. A key feature of the ES250P is its 12-inch polycellulose driver, which ensures clarity and precision in bass reproduction.

One of the significant technologies utilized in the ES250P is JBL's patented Bass Reflex design. This technology enhances the overall efficiency and output of the subwoofer, allowing it to produce deep bass sounds with minimal distortion. The system also includes a low-frequency crossover, adjustable from 40 Hz to 120 Hz, which allows users to precisely tailor the bass response to their specific listening environment.

Connectivity options are essential for versatility, and the JBL ES250P does not disappoint. It features both line-level and LFE inputs, making it compatible with most home theater receivers.
