The Wharfedale Pro DELTA-X18B 4-ohm variant delivers the same deep, powerful low-frequency performance as its 8-ohm sibling, tailored for amplifier configurations that deliver maximum power into lower impedance loads. The custom Wharfedale Pro 18″ driver handles 800W RMS (1600W Programme) and produces a peak SPL of 134dB, providing the foundation for high-impact live music, DJ and installation systems. Housed in a rugged, road-ready plywood enclosure with a durable finish, secure handles and top pole mount, it stacks seamlessly beneath DELTA-X full-range cabinets. Choosing the 4-ohm model lets system designers extract full rated output from single-sub-per-channel amplifier setups. Combine with DELTA-X series tops for a complete passive PA with serious low-end authority.
