The data sheet that Apple provided for the AppleDesign Powered Speakers II described them as “audiophile-quality…designed to work perfectly with virtually any personal computer, portable CD player or audio cassette player and with any television that supports sound output.”
The design of the rear speaker leg allowed the speakers to be adjusted to various angles. The power and volume controls was located in the front of the right speaker and an included cable with 3.5 mm plugs that connected the two speakers. Volume and an external headphone port were also located on the front of the right speaker. A stereo audio input port was located on the rear of the right speaker.
The speakers delivered 90 dB at 0.5m at 200Hz. Each speaker measures 6.8 inches tall, 4.1 inches wide, and 3.9 inches deep. The speakers were available as a set and as a part of the Apple Multimedia Kit for Macintosh.
This AppleDesign Powered Speakers II model is beige and matches Apple desktop computers sold at the time. Another version, considered far more rare, was also available in black with silver metallic Apple logos.
