18Sound Kit 12

Speakerstore - 18Sound Kit 12 An effective, high performance and easy to build two way loudspeaker system for high performance in a very compact and portable enclosure.

An “already optimized” passive crossover network greatly simplifies the system setup.

The 12W700 woofer has been combined with the ND1090, Neodymium Compression Driver, mounted on a 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 12ND830 woofer is the perfect option if equivalent sonic performaces are required while greatly reducing system weight as well.

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.
It’s 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.
