Audioengine A5+N Powered Bookshelf Speakers
Audioengine 5+ (A5+) Premium Powered Speakers deliver audiophile-quality sound and features at a price that continues to set the standard for affordable high-quality audio. Connect your iDevice, computer, TV, or any other audio component for great stereo sound in any room. The goal of Audioengine is to provide a high-end listening experience at affordable prices with easy to use, high-quality products. The Audioengine 5 powered speaker system was Audioengine's flagship model and has become a best seller. The new A5+ has the same award-winning signature sound as the original A5 but includes customer-requested upgrades and features. With custom Kevlar woofers, silk dome tweeters, and hand-built cabinets, the Audioengine 5+ includes a remote control, dual audio inputs and enhanced thermal management. You can charge your iDevice via the USB power port and also add a subwoofer to the variable output. Connect Audioengine 5+ to your computer's headphone jack or pair with a USB DAC to achieve an even higher level of sound quality. The Audioengine 5+ works with any computer and there's no software to install or settings to change. Built-in power amplifiers save space and eliminate the need to connect Audioengine 5+ to a stereo receiver or external power amp. Simply plug the left speaker into an AC outlet and connect the included speaker wire from the left to right speaker. All internal components of the A5+ are tuned together, providing a more efficient system requiring less power than passive speakers and amplifiers. With superior stereo separation and incredible imaging, A5+ has a clear sonic advantage over boomboxes or all-in-one systems. You won't hear any enhanced super-mega-hyper-monster boomy bass from these powered speakers. As with the original A5, the low end from the A5+ is real bass, very near to the originally-recorded music. From rap to classical to movies, you'll get tight, punchy bass with an awesome growl that will make you smile - regardless of the volume level.
All of the simple but useful features and same signature sound of the award-winning A5+ wrapped in rock solid and beautifully hand-finished bamboo. Bamboo is an excellent alternative to hardwoods and the dark bamboo used for the Audioengine A5+N cabinets is not a stain, but achieved through a specialized heating process. As the wood is pressure heated, the sugar compounds inside the bamboo are "carbonized" which in turn darkens the bamboo to a rich caramel color. Awesome sound, great looks, eco-friendly, and panda-safe.
Audioengine designs and manufactures our own tweeters, woofers, and other critical components. In other words, these are not "box built" speakers with off-the-shelf parts but custom-designed to our specifications. What we do not fabricate directly in our factory we have made to our designs (parts such as transformers, magnets, and wiring harnesses, for example). The cabinets, drivers, bass port designs, amplifiers, and crossovers are all painstakingly tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires much less power than passive speakers and a separate integrated amplifier or similar A/V components.
Audioengine uses audiophile-quality, ferro fluid cooled silk dome tweeters with neodymium magnets. Silk tweeters hold up well under high power and the edge-driven design gives very smooth response. The woofers are Kevlar woven glass aramid composite with rubber surrounds. Kevlar is obviously very strong, which means that the woofer retains its shape when being driven at high levels. The speaker materials and construction are robust enough to stand up to some serious thrashing, so speaker grills aren't needed and they will sound and look great after many years of use.
The amplifiers in Audioengine speakers are located in the left speaker and are a conservatively rated analog design. All components are tuned together for each model, which provides a much more efficient system requiring less power than passive speakers and separate amplifiers. Circuit boards for the power and preamp sections are mounted for maximum mechanical shock protection.
Power transformers are a large contributor to the overall audio performance, especially in the low end. Again, no off-the-shelf parts. Audioengine uses gapless core toroidal transformers which have a tighter radiated magnetic field, directly translating to lower noise. They are lighter than standard, lower-cost "EI" transformers and also generate less heat.
Both drivers are directly video shielded and allow the user to place the speakers within a few inches of a video monitor. This shielding also offers protection for hard-drive digital music players.
The Audioengine 5+ includes a 5V, 500mA USB power supply that powers later generation iPod, iPhone, and most other USB "bus-powered" devices. The USB port is for power and charging, not for data transfer or music syncing.
