Two 56-watt-per-channel digital amplifiers with DSP

The GLA-55’s transducers are driven by 112 watts (56 watts per channel) of cool-running, onboard digital amplification with DSP (digital sound processing) equalization. A chrome-plated, solid-copper bus connects signals from the amplifier to each driver with minimal resistance and signal loss. An integral heatsink and fully shielded amplifier enclosure eliminate any potential for troublesome electrical interference.

Easy-to-use touch controls

Just a touch of a button increases or decreases the GLA-55’s playback volume. Touching both volume controls simultaneously mutes the playback; touch them again to un-mute. An LED on the front of each speaker lets you know when the system is set to on, standby or mute mode.

Total input compatibility

The GLA-55 speaker system is compatible with virtually any audio device that features an analog output connector. A stereo 1/8-inch (3.5-millimeter) mini-jack lets you enjoy the ultimate audio performance from a variety of playback devices, ranging from desktop and laptop computers to MP3 and CD players.

Atlas AL woofers

Engineered specifically for the GLA-55, each 3-inch (75-millimeter) Atlas aluminum-cone woofer is capable of peak-to-peak excursions of nearly an inch. That is equivalent to the performance of woofers six times as large, with remarkably tight, accurate bass reproduction.

CMMD Lite tweeters

Featuring the same edge-driven Ceramic Metal Matrix Diaphragm® (CMMD®) Lite dome tweeter (patent nos. 6,327,372 and 6,404,897) found in high-end Harman Kardon loudspeakers and home-theater systems, the GLA-55 takes multimedia audio to a new high standard, with linear frequency response to 20kHz.

Slipstream port design

All bass ports reduce distortion by venting the internal pressure created by the normal movement of woofer cones. But the revolutionary shape of the GLA-55’s proprietary Slipstream port provides more surface area outside the enclosure than conventional cylindrical ports, thereby creating an “adverse pressure gradient” – a fancy, high-tech way of saying that the loudspeaker increases bass output with dramatically reduced port noise and distortion.

Harman Kardon sound: A legacy of achievement

Exemplifying the balance among high style, modern design and audio ingenuity, the AVR 1565 receiver fully embodies the spirit of Harman Kardon innovation, a legacy that discerning audio enthusiasts have revered for almost 60 years. Harman Kardon engineers have consistently advanced the science of sound, developing products that are dedicated to quality, durability and, most importantly, generating rave reviews from audiophiles.

Rated 5 out of 5 by from Perfect! I've owned these speakers for about 4 years now. The first thing you notice about them is that they are visually stunning. They are worthy of inclusion at the MOMA! Although they are designed to be computer speakers, I used them for my television. Setup is straightforward & easy. The second thing to notice is that the sound matches the looks. Sometimes when dealing with DSP, you just don't know exactly what you're going to get. All I can say is that whomever voiced these speakers got it right! Timbre, tonality, dynamics, sound staging, separation & presence........ All are on point. The GLA-55's are rated down to 35Hz & I have no reason to doubt it. They actually make a subwoofer unnecessary unless you want that bottom octave for your music or action movies. The highs are impressive as well. They are airy & crystalline without becoming harsh. The midrange is equally as nice. There can be a slight chestiness in the lower mids but that can be ameliorated by careful positioning. The bottom line is that as powered computer speakers, they are at the top of the line. Both visually & sonically they make a statement. When you take into consideration that no additional equipment it necessary (no amplifier, no subwoofer), the price is compensatory with the level of performance offered. Well done!
