The A5+ 5" Active 2-Way Speakers (Pair, Black) from Audioengine provide high-quality audio in a compact and stylish design, ideal for use with a variety of audio sources and devices. The system consists of an active left speaker and a passive right speaker, which are connected together via full-size gold-plated 5-way binding posts. Each speaker has a hand-built cabinet made from 0.75" thick MDF wood. Each cabinet contains a custom 5" Kevlar woofer and a 0.8" silk tweeter to provide clear, detailed audio with a wide frequency response and excellent realism.
The cabinets have rear-facing bass ports to extend low frequency response and tweeter waveguides to provide a wide dispersion pattern and realistic stereo imaging. The left speaker has internal Class-AB amplifiers that provide a combined system power of 150W to deliver a strong performance with low distortion. The rear panel offers 3.5mm and RCA inputs, allowing you to connect computers, MP3 players, smartphones, and any other product with 3.5mm or RCA outputs. The speakers are also compatible with Audioengine wireless audio adapters, and Apple's Airport Express and AirPlay.
The active speaker also has a stereo RCA output so you can connect an additional device, such as a subwoofer. A USB power/charging output allows you to charge small devices such as MP3 players or mobile phones while you listen to music. A convenient front-panel volume control lets you make quick adjustments. Protection circuitry includes output current limiting, thermal over-temperature, power on/off transient protection, and a replaceable external main fuse for lasting reliability. The speakers are also magnetically shielded for safe use near video monitors and other electronics.
The bottom of each speaker has a high-density isolation pad to reduce vibrations and reflections when used on a table or desk. There are also 1/4“-20 inserts so you can mount the speakers on stands. The system has a selectable operating voltage for international use. A convenient remote control is included for controlling the speakers. You are also provided with connection cables and carrying bags for quick and easy setup.
Compact and Affordable The compact design is ideal for use in bedrooms, offices, dorm rooms, and any other spaces where high-quality audio is desired in a compact design Easy Setup Simply connect the active left speaker to the passive right speaker using the included cable, plug the active speaker into the wall, connect your audio source, and you're ready to go! The speakers have full-size gold-plated 5-way binding posts for a high-quality connection and signal path Hand-Built Cabinets Each cabinet is hand-built from 0.75" thick MDF wood. Each component is custom-designed and tuned together for a high level of efficiency and audio performance Custom Drivers Each cabinet contains a custom 5" Kevlar woofer and a 0.8" silk tweeter to provide clear, detailed audio with a wide frequency response and excellent realism. The strong materials and neodymium magnets are robust and efficient to retain their shape, even when being driven at high volume levels Bass Ports and Waveguides The cabinets have rear-facing bass ports to extend low frequency response and tweeter waveguides to provide a wide dispersion pattern and realistic stereo imaging Class-AB Amplifiers The left speaker has internal Class-AB monolithic amplifiers with gapless core toroidal transformers that provide a combined system power of 150W to deliver a strong performance with low distortion RCA and 3.5mm Inputs The rear panel offers 3.5mm and RCA inputs, allowing you to connect computers, MP3 players, smartphones, and any other product with 3.5mm or RCA outputs.

High Performance, Compact Size, Surprising Price
Don't settle for flat sound from your flat panel TV, and don't miss out on the excitement of digital surround-sound in your shows, movies and games. Great surround-sound doesn't have to take up a lot of space or cost all that much. The payback is family fun and entertainment excitement. Don't miss out.
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.

The M-1 has been engineered with the same design attributes and ethos as B&Wʼs larger ranges. Perhaps the most striking thing about the M-1 is the weight and strength of its curved aluminium cabinet. This is combined with a strong, glass-loaded ABS front baffle. Together they provide an excellent cabinet: the curved aluminium is stiff and the ABS offers excellent and appropriate damping characteristics.
The M-1ʼs drive units were developed by Bowers & Wilkins specifically for the design. The metal dome tweeter benefits from refinements developed for the new B&W 800 Series and includes Nautilus™ tube loading and neodymium magnets. The glass fibre bass/midrange coneʼs ability to absorb standing waves has been further enhanced by the inclusion of five strategically placed resin filled slots that further minimise distortion.
The result of this detailed cabinet and drive unit engineering has allowed B&Wʼs engineers to borrow another feature from the new 800 Series and utilise the simplest of electronic equalisation in the M-1ʼs crossover. Each of the drive units is fed by only a single, carefully selected component. This approach to crossover design, although painstaking as it relies on optimising all of the physical components in a design, is crucial in achieving its aim of neither adding to nor subtracting from the original signal.
The M-1 is available in three colour options - black, white and silver, each with chromium plated stem and table base.
