The modular nature of the Optima fly track system allows the cabinets to be configured for alternative applications. In reFlex specification you get the same cabinet with identical acoustic performance but without the fly track system. Handles, pole mounts and transit options are still included making reFlex suitable for touring applications where cabinets will only ever be ground stacked. Reflex will also include additional bass options that are suited to integration with Axis and mFlex range products. Optima fly tracks are available as an option to allow you to upgrade your reFlex specification product to Optima specification. Fly track kits fit B215, SB118 and SB218.
