For sale is a fully functioning AS-P4100 Subwoofer, and a bonus surround speaker set that is slightly less than fully functioning...includes a centre speaker (LS-C50B) and 4 surrounds (LS-50B). One of the surrounds does not work as a result of a drop, some time ago. Full disclosure: I have never opened the cabinet, and it could be an easy fix, or not. The star of the show here is the subwoofer though, as follows: Amplification Type: active Speaker Driver Diameter: 10" Speaker Driver Diameter (metric): 254 mm Nominal Output Power: 100 Watt Max (RMS) Output Power: 400 Watt Frequency Response: 23 - 120 Hz Audio Amplifier: integrated Connectivity Technology: wired Recommended Placing: floor-standing Power Source: AC power adapter Brand: Athena Product Line: Athena Audition Series 2 Model: AS-P4100 Driver Material: injection molded polypropylene DIMENSIONS & WEIGHT Width: 11.3 in Depth: 17.7 in Height: 17.2 in Weight: 28 lbs I'm including the surround speakers at this price, as it can easily work as a 2.1 system, and if you can get the malfunctioning speaker to work, you have a very decent full surround system.
