Athena P.5 Active 8" Subwoofer for Sale. Audiophile quality, Canadian made. Used, but in good condition. C/w owner's manual. Below is info from the manufacture....
Measuring only 10" wide, and having a height and depth of just over 13", the Athena P.5 provides low frequency reproduction all the way down to 27Hz, which is almost as low as the threshold of the human ear. The 8" injection molded woofer with rubber surround has a long excursion design to allow high output with very low distortion. The front vented enclosure allows more flexibility in placing the sub where you want to place it. It fires all of the low bass frequencies forward into the room, so you can hide it under a table, or place it next to your A/V gear, or even behind a chair - flexibility is the key!
There is a single, downward firing, eight-inch, polypropylene woofer directly above a large, frontward firing port. This relatively small enclosure with black ash veneer makes good use of an efficient design with its 75-watt RMS (225-wattpeak) mosfet amplifier. For ease of melding, both the volume and crossover controls are conveniently located on the front baffle of the enclosure. There is a line level input (to connect to the sub-out jack on your receiver) and speaker level inputs.
The Bass Range control adjusts the high frequency roll-off of the subwoofer. Continuously variable from 50Hz to 150Hz, it is used to precisely match the subwoofer bass reproduction with that of your main speakers.
The two position A/V Switch has a built in equalizer that can change the sound of the subwoofer. In the "Audio" or "A" position the subwoofer has a flat, or even frequency response curve designed for music playback. In the "Video" or "V" position, the equalizer will enhance the bass frequencies response for the "thump" and "excitement" of home theater soundtracks.
