Product Description
Skytone Stx828s 2X18" Powerful Subwoofer
18 inch Subwoofer
Dual 18" Bass Reflex Subwoofer
18" high power subwoofer system
Skytone Stx828s 2X18

Key Features:
1.Premium passive loudspeaker system
2.Very high power handling
3.Dual 18 inch, top quality ferrite magnet aluminum frame woofers for extended low-frequency output and extremely low distortion
4.Large vent area for reduced distortion
The STX828S is a high power subwoofer system containing two 18 inch, top quality ferrite magnet aluminum frame woofers in a front-loaded, vented enclosure. The enclosure is designed to present a minimum frontal area. The system offers complete input connection flexibility for compatibility with a variety of cabling schemes. A recessed, external switch allows selection of either contacts +1/-1 or +2/-2. By relocating an internal connector, it is also possible to drive each woofer discretely from a separate amplifier channel.
The enclosure is constructed of top quality birch laminate plywood and coated in USA imported environmental polyurea finish. Each woofer is housed in an isolated chamber and the enclosure is heavily braced to maximize low-frequency performance. The attractive CNC-machined, 14-gauge steel grille is internally lined with acoustically transparent cloth to provide additional driver protection and give a very professional appearance.
