Turbosound TQ18B – Single 18″ Reflex Loaded Subwoofer for Touring and Installation Applications
Availability: In stock
Product Description
TQ18B
The TQ18B is a compact passive single 18″ 4,000 Watt (peak) subwoofer that is ideally suited for a broad range of speech and music sound reinforcement applications in both fixed, portable and touring audio systems. The TQ18B is designed to work in conjunction with Lake DSP and Lab Gruppen amplification, providing optimal FOH performance, as well as considerable flexibility to readily adapt to varying venue requirements. Multiple bass array configurations and all pre-sets are available to download.
Key Features
- Cardioid-arrayable, reflex-loaded single 18″ subwoofer for touring and installation applications
- 1000 Watts continuous, 4,000 Watts peak power
- 18″ neodymium low-frequency transducer
- Designed for low-frequency extension of TQ series
- Seamless integration with Lab Gruppen amplifiers and Lake DSP for a complete system solution
- Flexible cardioid configurations and electronic delay steering provide superior rear rejection and pattern control
- Optimized tuning for extended low-frequency impact and accurate transient response
- Low distortion diverging Lense port (DLP) design for maximum sound pressure level
- Integral feet secure ground stacking
- Dual Integral M20 (3/4″ / 20 mm thread) pole mount socket to support satellite speaker configurations
- 15 mm (5/8”) & 18 mm (3/4″) plywood enclosure with extremely durable semi-matte black paint finish
- Neutrik SpeakON NL4 rear panel connector for input connection
- Front-mounted NL4 connector for rear-firing cardioid operation
Custom-Engineered Drivers
Turbosound is recognised worldwide for designing and building some of the most iconic loudspeakers and subwoofers. We take meticulous care and pride in maintaining that reputation by utilising only drivers designed and specified by ourselves to our exacting standards.
Enclosure Design
The low distortion design utilised in the TQ18B reinforces the low-frequency spectrum in program or live music, steep cut-off slopes and Large singular DLP Technology (Diverging Lens Port) ensure an effective acoustic transition for use with TQ series elements.
Construction and Connectivity
Finished in a highly durable semi-matt black paint, the cabinet is constructed from 15 mm (5/8″) and 18 mm (3/4”) plywood – and includes a rugged powder coated cloth wrapped perforated steel mesh grille. The rear panel connector plate carries Neutrik speakON * NL4 connectors for input and link connections to additional enclosures. The front grille also has an Neutrik NL4 connector to allow neat cabling when the enclosure is deployed in cardioid mode.
Integration with Lab Gruppen PLM+
With the ever-increasing complexity of modern-day sound systems. Seamless integration with the Lab Gruppen PLM+ is a prerequisite for Turbosound’s TQ series. Our engineers have prepared and meticulously designed a series of presets that will allow the user to achieve the maximum system performance and consistency possible. These can be found in the download section. Future FIR-capable platforms from Lab Gruppen will be supported.
Acoustic Simulation Tools
EASE GLL files are provided for the EASE Focus 3 Acoustics Simulation Software, which is available for free download. This allows accurate calculation of acoustic coverage, matching simulation strategy to DSP pre-sets with a selection of traditional forward-facing, cardioid and reversed end-fire pre-sets.
Architecture and Engineering Specifications
The loudspeaker shall be of the passive subwoofer type, consisting of one 18″ (460 mm) LF driver. Performance specifications of a typical production unit shall meet or exceed the following: frequency response, measured with swept sine wave input, shall be flat within ±3 dB from 40 Hz to 120 Hz and within -10 dB from 32 Hz to 200 Hz. Nominal dispersion shall be “half space.” Maximum amplifier output power shall be 4,000 Watts peak, Sensitivity, measured on axis, mean averaged over the stated bandwidth, shall be LF: 96.5 dB, 1 Watt @ 1 metre. Peak level at 1 m under half space conditions using IEC 268-5 pink noise with crest factor 4, with dedicated pre-set, shall be 138 dB. Dimensions: 525 mm high x 785 mm wide x 560 mm deep (20.66″ x 30.9″ x 22.04”). Net weight: 40.7Kg (89.73 lbs). The loudspeaker system shall be the TURBOSOUND TQ18B. No other loudspeaker shall be acceptable unless submitted data from an independent test laboratory verifies that the above-combined performance/size specifications are equalled or exceeded.
