X-Program by DLS: Born to Play

The DLS X-Program was designed for those that love their music and love to listen at high levels. This specialized line from DLS has everything you need for a high-end, audiophile sound system. With precise engineering, these items still offer complete control of your audio and help you preserve the sound quality. The X-Program from DLS is a Sonic Electronix exclusive and is the perfect blend of performance and price. Just like the rest of the DLS products, the X-Program is designed and engineered by DLS in Sweden.

Born with Extreme Technology

X-Program amplifiers use class AB technology that is either all on or all off, so these amplifiers have low heat build-up in idle positions and are nearly 90% efficient. These full range analogue class AB amplifiers produce incredible power from a compact package so you can fit them almost anywhere, even under your front seat! All X-Program amplifiers are 4-ohm and 2-ohm stable so you can maximize you’re wiring options for speakers or subwoofers. Low-pass and high-pass filters allow you to tune your system just right by feeding your speakers only the frequencies they can handle, which reduces distortion. Phase shift of 180 degrees allows you to keep your subwoofer in phase with your speakers for the best tonal accuracy. Wrapping everything up, the silver finned heat sink is elegant and efficient removing any harmful heat generated from intense musical sessions. X-Program amplifiers were born to play rough, don’t let their compact size fool you.
