Enjoy your audio from nearly any source with the hi-gloss white Audioengine A5+ Wireless Bluetooth Speaker System. This system features Bluetooth with aptX HD technology for wireless connectivity, plus stereo RCA and 1/8 inputs for traditional wired devices. The A5+ Wireless has a 2-way design with a built-in 50W RMS per channel amplifier. Each speaker sports a 130 mm Kevlar woofer and a 20 mm silk dome tweeter, and the system includes an aluminum remote control.
The speaker cabinets, drivers, bass ports, amplifiers, and passive crossovers are all tuned together, helping to provide a more efficient speaker system that requires less power than passive speakers and a separate amplifier or similar component. With all the electronics built into the left speaker, it's simple to connect your favorite audio device.
The Bluetooth built into the A5+ Wireless features aptX HD coding for enhanced sound quality when paired with an aptX HD-enabled source device; it's also backward-compatible with the SBC and AAC codecs for universal Bluetooth compatibility. aptX HD also allows for a broader Bluetooth range - up to 30 m - for multi-room use.
The A5+ Wireless uses the AKM AK4396A DAC for upsampling, helping to achieve a higher signal-to-noise ratio and a lower noise floor.
The amplifiers in the A5+ Wireless are located in the left speaker and features a Class-A/B analog monoblock design. This is engineered to provide enhanced audio quality and flexibility, and all the circuit boards for the power and preamp sections are vertically mounted for augmented mechanical shock protection.
The A5+ Wireless speakers use ferrofluid-cooled silk-dome tweeters with neodymium magnets. Silk tweeters are designed to hold up well under high power, and the edge-driven design helps provide a smooth response. The woofers are Kevlar woven-glass aramid composite with rubber surrounds. Kevlar helps the woofer retain its shape when being driven at high levels. The woofers are housed in cast-aluminum frames, which help provide high rigidity and high heat dispersion.
Power transformers are critical to audio performance, particularly in the low-end. The A5+ Wireless speakers use gapless-core toroidal transformers, which are designed with a tighter radiated magnetic field, translating to lower noise. They are lighter than the more common EI transformer and generate less heat.
Both of the A5+ Wireless speakers are magnetically shielded for safe placement near other electronics.
