Speakers may be the most important piece of the sound quality puzzle. eXcelon speakers employ oversized drivers to enhance the low-end range and large tweeters that improve mid-to high-range transitions — ideal for clear and dynamic vocals. Oversized woofers provide quick response and offer stable and powerful bass that remains true to the original recording. Specially designed for one car: Yours. The automotive listening environment is filled with acoustic challenges, so we build our speakers in a wide range of configurations and sizes. From two-way full-range speakers to advanced thin-mount subwoofers, all eXcelon components are designed to perform in sonic harmony with eXcelon amplifiers.
