A - [LF] 2 Neodymium Woofer with a 12” diameter, 3” voice coil (reex conguration).
B - [MF] 4 Neodymium Mid-Range with a 6.5” diameter, 2” voice coil.
C - [HF] 2 Neodymium Compression Driver, 1.4” exit throat, 3” titanium diaphragm (horn driver).
D - Phase plug with optimized chamber
E - Waveguides
F - Proles with horn's logarithmic trend
VIO-L212's acoustic optimization harmonizes performance (SPL, phase and frequency response, sound focus)
with design sizes and mechanical constraints.
Especially:
• the phase plugs [D] with optimized chamber increase the mid-frequency consistency
• the positioning and the distance of Mid-Range transducers contribute to clearly dened sound focus and
off-axis listening position
• the logarithmic trend proles [F] of the horn, avoid among others, the creation of constant reections
(modes) and increase the consistency of the mid-high section
• the waveguides [F] control the vertical directivity of high frequencies
