CORE 8218SA

Active 18-inch High Power Subwoofer

Features

The CORE 8218SA is an 18” active subwoofer system. The CORE 8218SA features a one channel, 1500W, Class D amplifier that is specifically designed to power its corresponding passive cabinet, the CORE 8218SP, but can be used in a full active line array setup if required or preferred. The CORE 8218SA is compact, lightweight and can be flown or ground-stacked and possesses high output capability with low-frequency extension. It contains a single Ultra-long 18” / 4” V.C. woofer is front-loaded and the rear of the low-frequency driver is reflex loaded to extend the low-frequency output to below the natural cut off point. The proprietary rigging system of the CORE8218SA is directly compatible with the CORE 82A, CORE 82P, and CORE 8218SP. Each enclosure is constructed with a threaded pole-mount socket on the top of each cabinet for use with the CORE82-BPSYS pole-mount and bracket system. The CORE 8218SA also features the latest digital signal processor and the NUCLEUS FIR by Sound Barrier™ Loudspeaker Management Software.

Class D Amplifier

Sound Barriers Class-D power amplifier technology packs tremendous performance operating with high efficiency in a lightweight solution. CORE82A amplifiers deliver an ultra-fast attack, realistic transient response, and impressive audio performance. More than enough to power the CORE 82A and an additional CORE82P. The amp is constructed with a solid machined aluminum structure, which not only stabilizes the amplifier during transportation but also assists in heat dissipation. To ensure the integrity of the amplifier's components in high-temperature settings, additional cooling fans have been integrated into the design.

NUCLEUS FIR BY SOUND BARRIER

Every CORE active unit functions with the NUCLEUS FIR by Sound Barrier™ Loudspeaker Management Software, providing all of the features and flexibility required to drive and align the CORE series systems. Incorporating traditional IIR X-over and parametric EQ functions in conjunction with revolutionary FIR modes, NUCLEUS FIR by Sound Barrier™ Loudspeaker Management Software is one of the most flexible, advanced yet user-friendly loudspeaker management software in the world. The software and integrated applications transform the CORE series system from an active line array system into a transcendent and revolutionary piece of audio technology no professional should be without

FIR PHASE CORRECTION

NUCLEUS FIR by Sound Barrier™ Loudspeaker Management Software features the FIR Phase Wizard, a step by step FIR system phase correction mode that maximizes the performance of the CORE series for efficiency and potency by phase correcting and adapting the system to its surrounding environment/ venue. The procedure only requires an ASIO box (audio interface), measurement microphone and CORE series line array system. The software automatically detects the ASIO box and measurement microphone when connected to the user’s PC.

Easy as 1 -2 - 3

Once the PC is connected to the CORE series system (via a RS485), the FIR Phase Wizard step by step instructions will guide user from IR measurement to FIR calculation. The Phase Wizard automatically processes measures and analyzes the test signal produced by the CORE system to allow for the systems environmental phase correction. Once the system’s environmental phase correction is complete, users can save the data onto their PC as an FIR Phase Wizard File and / or load onto the CORE series system cabinets. The FIR Wizard software and integrated applications transforms the CORE series sound reinforcement system from an active line array system into a transcendent and revolutionary piece of audio technology.

Thinking outside the box.

The CORE system amplifiers deliver an ultra-fast attack, realistic transient response, and impressive audio performance that is more than enough to power a CORE active array module and an additional CORE passive array module. The amp is constructed with a solid machined aluminum structure, which not only stabilizes the amplifier during transportation but also assists in heat dissipation. To ensure the integrity of the amplifier's components in high-temperature settings, additional cooling fans have been integrated into the design.
