Jantzen Audio 051-0077 bassreflex port set | Ø70 x 235 mm

The Jantzen Audio 051-0052 bassreflex port set offers a refined solution for achieving deeper, more controlled low-frequency extension in your speaker cabinets. Designed for audiophiles and DIY enthusiasts alike, this pair of flared ports is ideal for use in high-fidelity loudspeaker builds, subwoofer enclosures, or custom audio projects where precise bass tuning is essential. Whether you are upgrading an existing design or constructing a new system from scratch, these ports help to minimise port noise and turbulence, ensuring clean, articulate low-end performance.

Each port measures 70 mm in diameter with a 235 mm length, providing ample volume for effective bass reflex tuning. The flared ends reduce air velocity at the port openings, which significantly lowers distortion and chuffing, even at higher output levels. Constructed from durable, rigid materials, these ports maintain structural integrity under pressure, contributing to consistent acoustic behaviour. The set includes two identical ports, allowing for symmetrical placement in stereo or multi-driver configurations. With a sleek black finish, they integrate seamlessly into most cabinet designs. Backed by Jantzen Audio’s reputation for quality components, this port set delivers reliable, high-performance bass extension for discerning listeners.
