One popular way to improve the multimedia experience on a PC is with a set of external wired computer speakers, and Harman Kardon HK19.5 Computer Speakers provide a balance between performance and practicality. With a 6.7-inch height, 4.5-inch depth and 4.3-inch width for each of these Harman Kardon Computer Speakers, and no bulky subwoofer to place, the system is compact with a minimum of wires. Speaker housings are designed to complement the look of any computer or laptop system and the minimalist setup reduces clutter. These two-piece Harman Kardon HK19.5 Computer Speakers are capable of 12-watt sound output, with 80 Hz to 20,000 HZ frequency response at 10 percent total harmonic distortion. These wired computer speakers each feature a 3-inch transducer that is magnetically shielded to reduce interference, as well as a tapered port bass reflex enclosure to offer deep bass reproduction without need of a standalone subwoofer. These Harman Kardon Computer Speakers are both Mac and Windows PC compatible (they can also be connected to any portable audio device that uses a standard 3.5 mm headphone jack) and feature a front-mounted LED indicator that confirms successful connection to a sound source. Harman Kardon HK19.5 Computer Speakers also include front-mounted volume and tone control knobs to easily customize sound.
