FS 5

Our Flagship All-In-One. Same Great Theater Performance, Slimmer Profile.

Home theater sound has come a long way in the past 20 years. Back then, it was common to use full-sized speakers for the three front Left-Center-Right (LCR) channels. This is still an excellent choice for some rooms. However, for the decor-conscious or for secondary rooms, multi-speaker setups such as these are less desirable.

The Atlantic Technology FS5 Front Stage Loudspeaker was designed for just these applications.

The FS5 is a true, no-excuses high-fidelity loudspeaker system that contains all three front channel LCR speakers in a single enclosure. Its sleek, trim cabinet is sized and proportioned to look perfect when used with thin-panel LED/LCD TVs with screen sizes from 50 inches and up. The FS5 can be wall-mounted, placed on a shelf or used with Atlantic’s special Shelf-2405, which provides a shelf attached directly to the flat screen TV itself.

Acoustically, the FS5 is the genuine article. Drawing upon Atlantic Technology’s decades of expertise designing and manufacturing high-fidelity speaker systems of the very highest quality and performance, each of the three independent speaker systems within the enclosure contains 4.5-inch CPP woofers and an ultra-wide dispersion ¾-inch silk dome tweeter. Blended together by an audiophile-grade crossover network, the FS5’s sound is smooth, vibrant and spacious, with the unmistakable detail and effortless quality found in all Atlantic Technology loudspeakers. Its response extends down to 80Hz, more than deep enough for any accompanying subwoofer to be totally non-localizable.

The FS5 delivers exactly what you demand in a top-quality home theater system: great sound, looks that blend into your decor and flexible mounting options that accommodate any scenario.

Reducing Diffraction to Ensure Maximum Intelligibility

Sound waves emanate out from a woofer or tweeter the way that ripples in a pond emanate away from the spot where you tossed in the pebble. But if you put something in the water near that spot—like the leg of a pier—when those ripples hit the obstruction, they’ll break up into many smaller waves and the smoothness of the original wave is gone.

That’s exactly what happens when a speaker sends out its sound into a nearby obstruction—like the frame of a typical grille. The sound hits that frame—like water ripples hitting a post—and the sound breaks up, smearing the clarity of the original signal.

The drivers of the FS5 (and also our FS3, LCR2 and LCR3) are mounted in a dense resonant-free mounting plate that fits into a reciprocal cutout in the grille frame. The result is that the drivers “see” a smooth local acoustic environment, so none of their sound diffracts off the blunt inner surface of the grille frame, the way it does on a conventional speaker. Instead of multiple “ripples” interfering with each other, the FS5’s sound is always clear and unfettered, for maximum clarity.
