The kit includes x1 12W750 woofer has been combined with x1 ND1090, Neodymium Compression Driver, mounted on x1 XT1086 horn in order to obtain smooth frequency response, precision directivity control and high power handling.

Unique 18 Sound Elliptical-Spheroidal waveguide technology assures constant coverage at mid and high frequency with precision and stability, and good array-ability if used in multiple units.

Due to the ND1090 special design, unique in the market featuring a lowered resonance frequency (about 700Hz), it has been possible to set a relatively low crossover frequency for a 1 Compression Driver (1.6kHz) yielding improved directivity control and definition, still not sacrificing power handling.


The enclosure should be made out of Baltic birch plywood (15mm thick).
The vents can be made with standard plastic pipe with internal diameter of 78mm and 35mm deep.
All the used bolts should be the M5 type (5mm diameter), 35mm deep. 8.8 steel type or better is strongly suggested.
M5 T-Nuts are recommended to be used in conjunction with M5 bolts.
Its strictly necessary to provide for proper cabinet internal acoustical damping with absorptive material. High density damping material, such as Dacron or other synthetic fibres, is required for best performance.
