The ICC-4H is a kit of two inter-cabinet couplers designed to fly a TCS-B15A or TCS-B15B subwoofer together with a Contractor Series mid-high element. Each coupler is CNC machined from steel, finished in semi-matt black powder coat and supplied with all M10 captive fast-pins and stainless steel hardware required to mechanically lock the two cabinets together for flown sub-on-top or top-on-sub configurations. Designed and engineered in the U.K. by Turbosound.
