The black Audioengine A5+ 2-Way Bookshelf Speakers 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 gold-plated 5-way binding posts. Each speaker has a cabinet made from 0.75" thick MDF wood and contains a 5" Kevlar woofer and a 0.8" silk tweeter to provide clear, detailed audio with a wide frequency response and enhanced 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 100W RMS 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 source with 3.5mm or RCA outputs.

The active speaker also has a stereo RCA output so you can connect 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 an 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. An aluminum remote control is included for controlling the speakers. You are also provided with connection cables and carrying bags for quick and easy setup.
