Low-frequency support for installed systems, with compact 6 inch units through to 18 inch cabinets from Optimal Audio’s Sub series and NEXO’s eLS installation range, plus Biamp options, in black and white finishes for visible positions.

An install sub does a different job from a touring sub: it fills in warmth and weight for bars, restaurants, gyms and retail rather than chasing maximum SPL, which is why small-format models such as the Sub 6 exist and why they often hide above ceilings, under seating or behind joinery. Size against the room and the programme material, not habit; a 10 or 15 inch unit covers most hospitality spaces, while 18 inch cabinets like the Sub 18 and eLS18 belong in venues with live music or DJs. Check the crossover plan and amplifier channel count early, since a sub usually claims a dedicated low impedance channel even on otherwise 100V jobs, and confirm enclosure orientation and fixing method if it is going into joinery or a void. White variants across the eLS and Sub ranges keep exposed positions tidy.

Full-range install speakers and the amplifiers to drive the whole system are in the adjacent categories, and we can sanity-check a sub choice against your zone layout.
