The IsoWave D4 3-Way Speaker System design emphasizes on consistency and linearity of on and off axis frequency response providing more spatially consistent sound compared to designs utilizing offset drivers. The enhanced sonic accuracy of IsoWave Speaker System is primarily possible due to the carefully integrated coaxial solution.
The Mid-High section of IsoWave D4 incorporates a 12″ extremely low distortion Low-Mid driver in conjunction with a coaxially mounted 1.75″ voice coil high frequency compression driver. The High frequency driver is loaded with a 90° horizontal X 60° vertical waveguide. This sophisticated waveguide also loads the 12″ low frequency driver. Together the system forms a high sensitivity, high SPL motor system with exceptional linearity and directivity control.
The system is further loaded with a 90° horizontal X 60° vertical large horn made of MDF enhancing propagation control down to 250 Hz . The horn can be vertically tilted by from 0° to 22.5° in increments of 2.5° to accurately achieve desired vertical coverage.
The low frequency section is powered with four 15″ long throw weather resistant Low frequency drivers. The Low frequency enclosure is optimally coupled to the Mid-High section to reproduce lobe free wavefront. The resultant frequency response is uniform and easy to equalize when required. DSP settings are provided for optimum performance when using either a Bi-amp or tri-amp configuration.
