•An effective, high performance and easy to build, two
way loudspeaker system for high performance in a
relatively compact and portable enclosure.
•An “already optimized” passive crossovernetwork
greatly simplifies the system setup.
•The 15W700 woofer has been combined with the
ND1460 Neodymium Compression Driver, mounted on
a XT1464 horn in order to obtain a smooth frequencyresponse, precision directivity control and high power
handling.
•Unique 18 Sound Elliptical-Spheroidal waveguide
technology assures constant coverage at mid and high
frequency with precision andstability, and good arrayability if used in multiple units.
•A crossover frequency set in the 1.5kHz range, yields
very good power handling and operation reliability
while not sacrificing directivitycontrol and mid-range
sound quality.
•The 15ND830 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).

•M5 T-Nuts are recommended to be used
in conjunction with M5 bolts.•The vents can be made with standard
PVC plumbing pipe connections with
internal diameter of 96mm, as described
at page 13.

•It’s strictly necessary to provide for
proper cabinet internalacoustical
damping with absorptive material.

•All the used bolts should be the M5 type
(5mm diameter), 35mm deep. “8.8” steel
type or better is strongly suggested.

•High density damping material,such as
Dacron or other synthetic fibers, is
required for best performance.
•The following example image show the
proper damping material disposition.
