Product Details

Harman Kardon GLA-55 Two-Piece Speaker System - GLA55

Every detail of the GLA-55, from the facets of its bass-reflex enclosures to its custom chrome tubing, has been designed to complement its astonishingly high sonic quality. From the powerful bass of the Atlas™ woofers to the crystal-clear highs of the CMMD® (patent nos. 6,327,372 and 6,404,897) tweeters to the touch-sensitive volume controls, the GLA-55 system is audio luxury defined. It’s also versatile enough to work with your computer, iPod, or virtually any audio device with a 3.5mm (1/8") output.

The First Audiophile Quality Sound System for Multimedia Devices

After years of relentless advancement in the power and sophistication of computers,digital audio players, video consoles and other entertainment devices, multimedia audiohas finally caught up. The Harman Kardon GLA-55 audio system brings impeccable sonic performance, stunning design and exquisite craftsmanship to the desktop forthe first time, forever raising expectations of what multimedia sound can be.

Easy-to-use Touch Controls
Just a touch increases or decreases the volume. Touch both volume controls simultaneously to mute; touch again to unmute. An LED on the front of each speaker lets you know when the system is on, in standby, or muted.

Total Compatability
The GLA-55 speaker system is compatible with virtually any audio device with an analog output. A stereo mini jack connection allows you to enjoy the ultimate audio performance from a variety of devices such as desktop and laptop computers (all platforms), MP3 players and CD players.

Advanced Technology for the Audiophile

Digital Amplification and Sound Processing.
GLA-55 transducers (1) are driven by 112 watts (56 per channel) of cool-running onboard digital amplification with DSP (digital sound processing) equalization. A chrome-plated, solid-copper bus delivers the signal from the amplifier to the speakers with minimal resistance and signal loss. An integrated heatsink and fully shielded amp enclosure eliminate the potential for electrical interference.

COE (Computer-Optimized Equalization)
The GLA-55 system equalization has been computer optimized to provide a rich soundstage over a wide range of listening positions.

OCT (Optimized Compression Topology)
The GLA-55 utilizes a proprietary compression technology which ensures clean, accurate sound at high output levels.

Atlas™ AL Woofers.
Engineered specifically for GLA-55, the 3" Atlas aluminum-cone woofer (2) is capable of peak-to-peak excursions of nearly an inch. That’s equivalent to woofers six times as large, delivering remarkably tight, accurate bass reproduction.

CMMD® Lite Tweeters.
Featuring the same edge-driven Ceramic Metal Matrix Diaphragm (CMMD) dome tweeter (3) found in high-end Harman Kardon loudspeakers and home theater systems, the GLA-55 takes multimedia audio to a new high, with linear response to 20kHz.

Slipstream Port Design.
All bass ports reduce distortion by venting the internal pressure created in the normal movement of woofer cones. But the revolutionary shape of the GLA-55’s Slipstream port (4) provides more surface area outside the enclosure than conventional cylindrical ports, creating an “adverse pressure gradient.” That increases bass output with greatly reduced port noise and distortion.

PMMA Enclosure and the Annealing Process
The GLA-55’s enclosure material is the same as what is used in bulletproof glass. Harman Kardon then takes this material and puts it through an annealing process. This includes baking each enclosure at 80 degree C for 4 hours. This process provides increased dimensional stability by realigning the molecular structure of the enclosure material. To further enhance performance the GLA-55’s enclosure has a variable wall thickness which creates a stiff and resonance free enclosure. The net result of the annealing process and variable wall thickness enclosure is increased bass performance and a reduction in unwanted distortions and resonances.
