Altec Lansing BXR1120 Computer Speakers (left & right). AC 9V - 4.5W. Includes power adapter. Right speaker has knobs on front for power, volume, tone, headphone jack, and aux. These were my own personal computer speakers that I stuck in a closet and forgot about. I've pulled them out, tested them, and they are now ready to go to a new home. Please see photos...this is exactly what you will receive.
