No one could have predicted its subsequent success back in 1993, when a small loudspeaker called the ELAC Elegant 305 hinted at the promise of great things to come. Aesthetics and sound in perfect unity—the secret is aluminum. It guarantees high rigidity from low material thicknesses and makes a unique cabinet shape possible. The near-complete absence of a front baffle allows the sound to radiate with total freedom. The audible result is room-filling, unfettered and utterly captivating sound.
A compact 2-way, bass-reflex design, the BS 312 incorporates the multi-award-winning JET 5 tweeter and a new woofer specially developed to ensure that electric signals are flawlessly converted into a superlative audio experience. This perfect partnership endows the BS 312 with unprecedented precision and dynamics in any position.

The sonic miracles.
Be amazed by the volume these compact loudspeakers can produce. Both models in the Line 300 deliver an extraordinary audio experience for their size, thanks in part to aluminum cabinets that are rigid, lightweight and allow for a narrow profile that minimizes the diffraction effects of larger cabinets.
Crystal membrane driver
The eye-catching surface of the crystal membrane is more than just an attractive design feature of the BS 312. The Crystal Membrane (patent pending) design is based on ELAC’s Aluminum-Sandwich AS Technology. The crystal-shaped inverse aluminum dome is joined to the paper cone in a special gluing process to result in the desired sandwich construction. Resembling the surface of a large crystal, the aluminum-foil stamping stiffens the aluminum dome, diminishing resonances and minimizing coloration, while improving power handling and dynamics. The voice coil design of the driver results in an expanded frequency range, and driver surround allows for longer cone excursions for truly prodigious volume and lowest distortion, a unique engineering achievement for a driver of its size.
JET 5 tweeter
Delivering true high-definition sound, ELAC’s JET 5 tweeter used in the BS 312 enthralls with its lightning-fast response and wide dynamic range, offering minimal distortion, lots of headroom and a distinctly wider frequency range than conventional dome tweeters. The ELAC JET tweeter is one of the most legendary tweeters in the industry and has won international praise with its transparent and effortless sound image.
The JET tweeter was developed to perfection on the basis of the famous Air Motion Transformer by loudspeaker pioneer Dr. Oskar Heil. Its operating principle is based on a concertinaed-foil membrane, driven by a strong magnet system of neodymium rods. This motor drives the air considerably faster than the pistonic motion of a conventional driver, with gains in higher sensitivity and extraordinary dynamics. Due to many additional design changes, like an improved new neodymium magnet system, even higher efficiency, higher sound pressure levels and frequency response up to 50 kHz was achieved.
The core of the JET tweeter is the folded foil membrane. With a fold width of only 0.84 mm, a major requirement in the JET production is precision. To guarantee repeated accuracy and unchanging quality even with high production capacity, gluing and handling are now executed by two SCARA robots. The folding and fixing of the membrane, however, are executed by hand, since for production steps requiring extreme precision, the manual dexterity of skilled technicians is irreplaceable. Due to continuous improvement, the JET 5 tweeter creates an effortless, airy and resonance-free image up to 50,000 Hz, and with its linear frequency response is ideally suited for the reproduction of DVD-A and SACD.
Bass reflex port
The bass port of the BS 312 is a proprietary design feature. Flared on both sides, the double-flare port has been designed to minimize ventilation noises and to reduce friction losses of traditional ported cabinets.
Bass control
The sound of loudspeakers is heavily influenced by room-acoustics. In some cases the room shape and especially the furnishings offer less than ideal conditions for the optimum set-up of the loudspeakers, sometimes resulting in bass reproduction that is too strong. Closing the bass reflex port of the BS 312 compensates for unfavorable acoustic conditions when speakers are installed, for example, close to a wall. When loudspeakers are used close to walls or in small rooms and the bass is too prominent, the ELAC Bass Control plug can be used to improve the bass reproduction by reducing the low frequency output. Just insert one or both of the supplied ELAC Bass Control plugs into the bass port until the bass is at the correct level relative to the midrange and treble.
Magnetic shielding
With the cinema-friendly BS 302, you can watch television without having distorted color. Thanks to magnetic shielding, this loudspeaker can be installed right next to CRT screens or devices with hard drives sensitive to magnets without creating interference.

Two Way Bass Reflex Bookshelf Speaker System
Yamaha\'s NS-333 speaker system has been designed specifically for home theater applications. The bookshelf speaker is a bass-reflex design that can be used for main or surround channels and incorporates a 5\' Polymer-Injected Mica Diaphragm (PMD) cone woofer and a 1” aluminum dome tweeter. For improved imaging, the tweeter utilizes Yamaha’s exclusive waveguide horn.
Waveguide Horn
Unlike most homes, movie theaters use sound absorbing materials on walls and ceilings. The result is that the sound reaching your ears is the sound wave produced by the speakers rather than reflected off the walls. Yamaha has created wave guides that greatly reduce reflected sound and increase the proportion of directly generated sound waves reaching your ears. The result is a clear and precise sense of sound direction and placement.
Internally Wired with Monster Cable™
Yamaha has chosen to ensure optimum sound quality by internally wiring some of the components with Monster Cable™. This ensures a clean, clear signal from the crossover network to the speaker driver.
Magnetic Shielding
The speaker is magnetically shielded, so it can be placed on a TV or video monitor without degrading the picture via stray magnetic fields.
Performance Enhanced by a Handsome Cabinet
The EF series speakers are enclosed in an Elliptical Form cabinet with a high gloss black piano finish, which provides solid construction with minimal sound diffraction.
New Grill Design
New grill design and grill cloth provide an attractive and acoustically transparent protective cover for the drivers.

Small is beautiful. The 686 S2 is the most compact speaker in the series, but don't underestimate its power and precision. That's thanks to a new Decoupled Double Dome tweeter and improved design.
An ideal bookshelf or wall-mounted speaker, the 686 S2 is designed to fit into any space and still sound perfect. Its main driver is a 5-inch bass/midrange unit which benefits from a new 25mm voice coil which makes for a higher sensitivity speaker with bass more suited for placement near a wall.
Bass performance is vital but can often suffer in smaller speakers. Not in the 686 S2, however. That's because a front-firing Flowport, dimpled like a golf ball around the aperture for smoothly regulated airflow, delivers superior bass response without the risk of rattle. Its placement ensures the speaker cabinet is slimmer than predecessors and can be wall mounted without affecting performance.
Like the rest of the range, and despite its smaller size, the 686 S2 also features a Decoupled Double Dome aluminium tweeter for superior high-frequency response. The 686 S2 even features a built-in bracket for easy wall mounting, although this small, versatile and precise speaker sounds great anywhere.

TL1 Features:
The silk dome tweeter delivers a classic, clear, detailed Polk performance, with pinpoint imaging and smooth highs that are never tiring.
Time Lens® technology aligns the acoustic centers of the tweeter and mid-bass driver on the same spatial plane for superior imaging, while an acoustic lens incorporated in the grille smoothes the tweeter's frequency response.
The unique curved enclosure design employs non-parallel surfaces to strengthen the acoustically inert enclosure and deliver less audible coloration from internal surface resonances.
Because of its Extended Linear Motion motor structure, the moving parts of the drivers used in the Blackstone TL Series can move farther, more smoothly, in a smaller space than any other speaker driver in an enclosure this size, achieving the kind of dynamic response (clarity, volume) you'd expect from much larger speakers.
An aperiodic-tuned rear-firing bass port combines the extension of a ported enclosure with the smoother low-end of an acoustic suspension enclosure, controlling port air flow for the kind of big bass response, and perfect speaker-subwoofer blending, you'd never expect from a loudspeaker you can hold in the palm of your hand.
The Blackstone aerated polypropylene cone is lightweight, but stiff and strong, with longer linear excursion capabilities in a limited compact enclosure space, so it plays louder with less distortion.
A super-small long-throw mid-bass driver, tuned with our patented Dynamic Balance® technology, delivers astonishingly smooth, flat frequency response, superior transparency and detail, and the surprising ability to play really, really loud for such a small speaker.
Polk's proprietary, patented Dynamic Balance technology allows our engineers to design out distortion-causing driver and system resonances, so you only hear the good sounds.
Hi-Gloss "Blackstone" finish, a durable, deep automotive-strength finish that matches today's most stylish flat-panel TVs and furniture.
Compact means go-anywhere for Blackstone TL: on shelves, on the wall, on stands. Built-in keyhole slots and threaded inserts (that fit virtually any brackets) give you multiple mounting options.
Gold-plated, professional-style 5-way binding posts, for the most secure connection options.
All models in the Blackstone TL Series are available in convenient, professionally matched 5-packs for instant home theater solutions in any room. There are two complete systems available that include a subwoofer; everything you need for an explosive, compact, easy-to-connect home theater system. Plus, you can use individually-available satellites to expand your systems to accommodate 6.1, 7.1 and beyond.
