The KSR Amplification RCS/412™ straight cabinet combines unique design with superior construction techniques. Tuned for superb low end performance while minimizing brittle highs, this is the last cabinet you will ever need. Removable casters and recessed hardware come standard.


The cabinet is constructed of 3/4" Baltic (Russian) birch plywood with locked rabbit joints. During construction all joints are glued, pinned, clamped, and cured for maximum strength. The front baffle is secured with 12 screws from the inside allowing for easy grill cloth replacement. The rear panel is removable via 20 steel screws. All panels and hardware are gasketed making for an air-tight sealed cabinet. The handles and rear cover are recessed, further illustrating our commitment to building the best cabinet possible.


A parallel-mono jack plate wired for 16 ohms comes standard. Automatic mono/stereo switching is available via a Plug and Play jack plate. The standard stereo jack configuration is 16 ohms mono and 8 ohms stereo.


The front speaker panel is angled slightly to reduce the interaction of sound waves reflected off the cabinet back and into the speaker cone. This angle also points the speakers up a bit giving you similar benefits of a slant cab in a more solid and versatile straight package. The angled front along with a sturdy internal baffle ensure solid bass response with little resonance due to standing waves. The end result: Unbelievable bass response that is super tight and never 'boomy' or 'flubby'.


A wide array of speaker and covering options are all available standard. Choosing various speaker types allows you to refine the overall response to your playing. If you'd like speakers installed that are not listed, please contact us. If you already have speakers, unloaded cabinets are available. All wiring and instructions are included for an easy installation.
