Nexo chose Prolight & Sound for the debut of the ID24 series (ID stands for Inspace Definition), which comprises a line of ultra-compact, full-range speakers and two subs, S110 and S210.
Because there are numerous versions – between the touring and installation versions and the “à la carte” variants – the ID24 enclosures cover a wide range of applications, starting with under-balcony fills, front-fills for theatre or concert stages, or even monitoring applications.
ID24 incorporates two 4″, long-excursion, shielded transducers mounted in a ‘V’ configuration around a 1″ (½” exit) compression driver loaded by one or more specially-developed waveguides.
These very compact speakers (309 mm W x 132 mm H x 233 mm D) can deliver an impressive 126 dB peak SPL, thanks to their nominal sensitivity of 100 dB (1 W @ 1 m) over the band of 110 Hz–20 kHz (+/-3 dB) and their peak applicable power of 400 W.
Their nominal 16 ohm impedance allows the use of a single NXAMP4x1 Powered Controller, in 4X4 mode with dedicated presets, to drive 16 enclosures. If they are amplified using some other platform, the Nexo DTD controller supports the same presets.
A key feature of ID24 enclosures is that they can be used both vertically and horizontally, with the possibility to rotate the HF waveguide using a rotating knob on the rear of cabinet. Therefore, these enclosures offer two different directivity patterns in each plane.
The basic versions – Touring, ID24t and Installation, ID24i – exhibit a directivity of 120° H x 30° V (or vice versa) and differ only in finish (grill and mounting hardware) and the type of connector: Speakon NL4 (touring) or captive-cable terminal block (installation).
The IP55-rated ID24i is available in white and black and can be used outdoors.
The ID24c “à la carte” version is available with three additional waveguide options: 60° x 60° and 90° x 45° symmetrical dispersion, and 60°-120° x 45° asymmetrical. It is also available in a wider choice of colors.
The cabinet of ID24 is constructed in a molded polyurethane composite that offers lightness, rigidity and strength. Numerous mounting points are provided on the metal plates of the top, bottom and sides. These allow the enclosures to be installed without using tools on Nexo (QRV bracket and QRF support) and third party mounting accessories, as well as pole mounts, truss mounts, wall mounts or on stands.
Two very compact and low-profile subwoofers complete the series : ID S110, with a single 10″ long-excursion woofer, and the dual-10″ ID S210. These subs feature cabinets in birch plywood and are loaded in an acoustic band-pass configuration. Their low profile and small footprint allow them to be easily concealed in an installation.
The S110 has a sensitivity of 97 dB (1 W @ 1 m) and can generate a peak SPL of 125 dB, while the S210 (sensitivity: 100 dB) can deliver 131 dB peak.
The crossover points for the full-range heads can be varied between 85 Hz and 120 Hz and the two subs offer a frequency response (-3 dB) that extends down to 45 Hz.
