Arup is an engineering and design consultancy with an acoustics practice. Its contribution to the directory is room design rather than equipment manufacture.

Design & approach

Arup brings together engineering, design, planning and technical disciplines for the built environment. Its contribution to an audio venue is consequently different from manufacturing an amplifier or speaker. The relevant project credit concerns the space and its engineering, and should be read alongside the equipment and installation credits.

Design / integration

Arup is credited alongside Studio Kos for the room at Public Records. This is an acoustic and design collaboration, separate from OJAS’s loudspeaker work.

Inside the system

Public Records has several distinct installations. The indoor Sound Room combines Void Nexus XL subwoofers, OJAS quad-15 slot-loaded midbass cabinets, Altec 1505B multicell horns and Faital supertweeters. Void and BGW amplification works with BSS processing; four Technics SL-1200MK2s and four Pioneer CDJ-2000NXS2s accompany a custom Isonoe mixer. The Bar Room uses replica Altec 816 midbass cabinets, OJAS cabinets with 500 Hz horns and Altec high-frequency drivers, plus Void Venu 115 subwoofers. Crown and BGW amplification accompanies analogue crossovers, with two SL-1200MK2s, two CDJ-2000NXS2s and an Isonoe mixer at the booth. The outdoor Nursery has an OJAS × NNNN fully horn-loaded four-way installation. A later Atrium installation uses six OJAS × NNNN ON M I assemblies and eight TL18 subwoofers. These room-specific systems represent different chapters and spaces, rather than components of one signal chain.
