Sub1.8H aspects

 Smart Series Smart1.0 Smart1.2 Smart1.5 Sub2.5R Sub2.8R Sub1.8H
Smart Series is the next generation high performance self powered loudspeaker system comprising three Full-range and three subwoofer models, expressly designed for all applications where versatility, compact dimensions and lightweight are essential, while keeping great performances and high efficiency with no compromise.
Smart Series meets the needs of touring houses, installations, and the most demanding live sound applications ensuring they can deploy a no-compromise, all-in-one solution featuring the legendary Loud Professional performances and comfort listening. Smart Sub1.8H is a fully Horn loaded system housing a single 18in. (460mm) long excursion transducer.
The optimized horn loading path consistently increases the LF efficiency also extending the frequency response.
Considering the compact dimensions and the system type, extended is the low frequency reproduction, specially in the lower end region where the unit is able to reproduce frequencies down to 45 Hz with a plenty and sensational sound impact for an unrivaled Bass-punch as you've never heard before!
The result becomes more evident specially when coupling several units in a large array for really long throw applications.
The special system ability to control the transducers linear excursion keeps really low the total harmonic distortion levels, still maintaining a great linearity in the lower frequency reproduction for the fastest transient response all over conditions.
A class D two channels amplifier module provides an exceptional output power, specifically designed for mono bridge applications where high output voltage level is required for only one amplification channel.
It's the perfect engine to drive high power rock solid single subwoofer as the Smart Sub1.8H. Highest grade audio accuracy is guaranteed by fixed frequency switch mode output stage, avoiding any intermodulation artifact, and by the new "Control Plus" board allowing to achieve +6 dB more in terms of Signal-to-Noise Ratio.
The Smart amplifier module is an extremely compact solution: power supply, output stage, DSP board and connectors are all included in a single, small, lightweight and protected chassis, and the perfect compatibility with the other Smart Series products allows to minimize efforts for mechanical development of different products.
As for all Smart products, the Smart Sub1.8H amplifier module is shaped and controlled using the DSP boards available to design the sound of the loudspeaker with a large set of processing algorithms.
To achieve best performances in terms of fidelity, output capability across the audience, Smart Sub1.8H combines onboard state-of-the-art transducers and Powersoft amplifier module.
A programmable DSP enables the networking connection. The management software Armonia-Pro audio suite allows to customize the sound based on the own specific needs and to upload four different standard presets for the most common applications. Versatility is a key attribute of the Smart Sub1.8H.
It is designed to meet a multitude of premium stand-alone and distributed sound reinforcement requirements: theatre, touring and portable live sound applications, corporate events, concert hall.
Ideal as the main PA in small-to-medium size rooms, it can also be used as a front/in/out-fill/drum-fill loudspeaker in large-scale systems supplemented by different full ranges of the Smart Series.
The M20 threaded insert integrated adapter on top panel allows the Smart Full-range to be stacked on.
Great performances, compact dimensions and lightweight make the Smart Sub1.8H incredibly smart and portable, just by broadening the applications range, specially in mobile solutions.
Significant construction criteria, combined with the latest technologies and innovative materials, ensure a great reliability over time.
Smart Sub1.8H cabinet is constructed from Birch-ply and has an impact and weather protected PCP (Polyurea Cabinet Protection) finish.
The system can be as well matched with the Loud Professional Smart Full-ranges, significantly boosting their LF extension.

Applications: Theaters, Conference Halls, Concert Halls, Large Scale Discos, Clubs & Bars.
