Overview
History
Large studio monitors are engineered to produce extended low frequencies at low levels. In opposite full range PA loudspeakers are not really full range; they are optimised for high efficiency above 60 Hz so require additional subwoofers to extend the lower frequency range.
There are few if any professional solutions for a compact cabinet providing extended low frequency at high SPL. D20 is such a solution – a compact 3-way point source designed without compromise to provide extended low frequency at high level.
Description
The D20 is a passive 3-way compact system, designed for small to medium installation applications where extended low frequencies, superior dispersion control and high fidelity sound are required.
The cabinet contains an extremely long excursion 12” woofer and an 8”/1.75” coaxial driver.
The advanced design aligns the acoustical centers of the transducers to produce a single point source. This unique loudspeaker technology provides a coherent wave front without hot spots. Precise directivity ensures uniform coverage with perfect time alignment between the components.
True Full Range
The cabinet contains an extremely long excursion 12” ultra low distortion cone driver covering the range 35 Hz – 400 Hz. The 3” voice coil is 32 mm high, ensuring linear excursion of 22 mm / pp at consistent magnetic force. Three aluminum shorting rings reduce inter-modulation distortion; minimise induction variation while reducing thermal compression. This design reduces dramatically the distortion of a typical subwoofer at longer excursion levels, and improves the overall sound quality providing deep and punchy bass.
True Coherent
At the heart of the D20 is the new developed 8”/1.75” coaxial driver. The 8” cone midrange covers the 200 – 1800 Hz range with high efficiency and smooth, linear response. The high frequency driver contains an ultra light 1.75” annular diaphragm providing exceptional transient response with very high efficiency from 1kHz to 20 kHz. This new transducer was engineered to radiate a single source, coherent 90° wave front for superior dispersion control and high fidelity sound.
Controlled Dispersion at High SPL
The low and mid range are overlapped in the range 200 – 400 Hz while mid and high range are overlapped in the 1 – 1.8 kHz range. This increases the maximal SPL of the system providing improved directivity control.
System Solution
The D20 is designed to work exclusively with dedicated CODA Audio DSP amplifiers as an integrated solution for DSP control, amplification, network remote control and diagnostic. The integrated solution ensures optimal performance and protection.
Options
Additional colours and weather protection options are available.
Applications
Designed for small to medium installation applications where extended low frequency range at high level is required but no subwoofers can be used. In fact two D20 systems will deliver same level of low frequency range and output as a single 18” subwoofer.
