Its extra-large, flow-optimized flare profiles ensure maximum port efficiency, while thick walls reduce unwanted resonance, making it the ideal choice for serious sound pressure level (SPL) enthusiasts. ## Description This is the two pack of 8 inch diameter Versa-Tune adjustable length port kit. Our Versa-Tune kit is the original adjustable length flared PVC port kit that changed everything. These aeroport kits can be assembled to any length between 8 inches and 21 inches, quickly and easily, for ultimate functionality. These are also perfect for box builders and audio shops who want to keep extra ports on hand for future use since they are not length specific. The smaller drop-in inner flare allows the port to be fully assembled prior to installation. We recommend assembly with a high quality packaging / shipping tape in order to retain adjustability, or pvc primer and cement can be used for a permanent assembly. This listing is for one port kit.
