Audioengine A5+ Wireless Bluetooth Bookshelf Speakers - Premium 150W Stereo Speakers for Music, Gaming, Turntables, Home Theater Systems - Powerful Studio Monitors
</p><b>Custom Components</b> <p>Audioengine designs and manufactures our own speaker drivers and other critical components. In other words, A5+ Wireless is not a "box-built" system with off-the-shelf parts, but includes custom-designed components constructed to our specifications. What we do not fabricate directly inside our factories we have made to our specific designs - parts such as circuit boards, transformers, magnets, and wiring harnesses, for example.</p> <b>Efficient Integrated Design</b> <p>The speaker cabinets, drivers, innovative bass port designs, amplifiers, and passive crossovers are all critically tuned together for each Audioengine model. This, in turn, makes for a much more efficient system that requires less power than passive speakers and a separate integrated amplifier or similar A/V components. We build all this goodness into the left speaker cabinet to make it super-easy to connect your smartphone, tablet, computer, TV, network player - or any other audio product.</p> <b>Built-In B1 And D1</b> <p>We've taken features from two of our best-selling products, the B1 aptX® Bluetooth® Receiver and the D1 24-bit DAC, and combined some of this circuitry with advanced speaker components to achieve a complete high-end analog and digital audio system.</p> <b>Amplifier Design</b> <p>The amplifiers in powered Audioengine speakers are located in the left speaker and are a conservatively-rated class A/B analog monoblock design. This is a more traditional speaker/amplifier marriage which provides excellent quality audio and greater flexibility. All circuit boards for the power and preamp sections are vertically mounted for maximum mechanical shock protection.</p>
