BRC PARAFLEX BASS patented  Low extended Driver technology that provides a very low-frequency response and no distortion, increased sensitivity, extended bandwidth, and improved phase coherence. High frequencies are handled by PARAFLEX BASS  5″ voice coil . Low-frequency drivers use BRC patented Progressive Transition Wave guides which offer dramatically advanced constant beam width and directive, lower distortion, and overall smooth frequency response free of high-Q peaks. The SCP118 Series multi-ply enclosures are manufactured with precision CNC engineering techniques that allow precise tolerances and consistent production. PARAFLEX Series is compatible with GOOD QUALITY AMPLIFIER, with low-frequency processing, ensuring that PARAFLEX Series enclosures are optimally processed. The PARAFLEX Series integrates with BRC Performance Manager which guides the system design for the best results.
