The SAR4 4-space rack case provides secure transport and storage for power amplifiers, processors, wireless systems, and other 19-inch rack-mount gear. Built for touring musicians, mobile DJs, and sound engineers who need professional protection without the weight penalty of steel cases. This 4RU case holds standard rack gear in a lightweight yet durable 3/8-inch plywood shell reinforced with steel L-brackets on each side. The front and rear removable doors feature dual 4-inch steel link locks for security, while stackable corners let you build multi-case systems for larger rigs. At 26 pounds, the SAR4 balances protection with portability. The 17.5-inch rail-to-rail depth accommodates most amplifiers and processors, with 20.5 inches of total depth when the rear door is installed. Black finish with aluminum rails maintains a professional appearance while spring-loaded handles on each side make lifting manageable for one person. Perfect for band PAs, DJ setups, and installed sound systems where gear needs protection during transport or storage. The case works equally well for permanent installations where equipment access and security matter. Houses power amps for small to mid-size venues, wireless receiver racks, or processing chains for live sound applications. The case includes 24 rack bolts for mounting equipment and comes ready to use out of the box. Seismic Audio backs the SAR4 with a one-year warranty and ships direct to your door.

The SAR4 accommodates most 4RU or smaller rack gear including power amplifiers, digital processors, wireless microphone receivers, and effects units. With 17.5 inches of rail-to-rail depth, it fits standard gear like QSC, Crown, and Yamaha amplifiers, plus most DJ mixers and audio interfaces that use rack ears. How much weight can this case hold safely? While the case itself weighs 26 pounds, the reinforced plywood construction with steel L-brackets can safely transport typical rack gear weighing up to 60-80 pounds total. Power amplifiers are usually the heaviest items, and most 4-space amps fall well within this range. Do the doors need to stay on during use? No, both front and rear doors are completely removable for permanent installations or when you need full access to controls and connections. The rear door removal gives you an extra 2 inches of depth clearance for cables and connections. Will this case stack with other Seismic Audio rack cases? Yes, the SAR4 features stackable corners that align with other cases in the Seismic Audio rack case line. This lets you build secure multi-case rigs for larger systems while maintaining easy access to individual cases when needed. What's the difference between this and a 6-space case? The 4-space case works best for single amplifiers or small processor rigs, while 6-space cases handle larger amps or multiple units. If you're running a simple stereo setup with one amp and a processor, the 4-space saves weight and space. Larger systems with multiple amps need the 6-space capacity.
