Danley Sound Labs has expanded the Jericho Horn Series with the introduction of the J4, a “supertweeter” that incorporates 64 one-inch compression drivers combining into a single point-source design.
The J4 extends the upper three to four octaves that can be consumed by atmospheric conditions to improve the presence and impact at great distances.
Combined with a high degree of pattern control, the J4 can produce these high sound pressure levels on axis while being -15 dB or more down off axis.
“The problem that led the industry to the line array in the first place was the inverse square law,” said Mike Hedden, Danley Sound Labs president. “You’d rip the faces off folks in the front row but leave folks in the back row asking for more. Since its reintroduction to the market many variations of line array designs have attempted to address this problem.
” However, all the elements interact, which makes the phase coherence, frequency response, and imaging detail of a line array system very different based on listener location with the net result being something that is anything but high fidelity. The Jericho Horns using our Synergy Horn technology and pattern control that only comes from large horns solve all of the problems that led to the line array, but without incurring all of the problems inherent to the line array.
“Listen to a stereo pair of our Jericho Horns and you’ll hear the phantom center channel, something only achieved with accurate phase relationships. As one moves off the center position even to extreme left or right, as long as you are in the direct field of both cabinets, you still experience some stereo imaging. Using a pair of J2s you’re listening to almost one-hundred drivers, yet the phase relationships are dead on accurate!.”
Now composed of four members – the J1, JH 2, J3, and J4—Jericho Horns are designed to provide high fidelity at great distances, applications that are commonly addressed with line arrays but with enhanced phase coherence, frequency response, and imaging detail more typical of a professional reference monitor.
The original J1 is effectively two horns in one: a low frequency horn together with a true 90 x 40 Synergy Horn. Capable of producing 3,000 acoustic watts in the subwoofer section, the J1 conveys impressive low end.
The 90 x 60 JH 2, and the more compact version, the 60 x 40 J3, are both true Synergy Horns across their full-range frequency responses and are seamlessly arrayable.
Of the first three, the J3 is purpose-built with the expectation that a subwoofer will provide low-end support. The other two can stand on their own, but play nicely with subs where desired.
In contrast, the J4 makes use of the same engineering principles, but for a very different purpose. Although its frequency response will naturally extend down to 600 Hz, the J4 is recommended for use with high-passed material above 2500 Hz. The J4’s beamwidth is a narrow 30 x 10, and it is hard-pack arrayable so that multiple units can seamlessly provide necessary coverage.
“The J4 is an industry first,” said Hedden. “Long have we recognized how severely high-end content can be attenuated due to air absorption, but conventional loudspeaker technologies weren’t able to effectively address the problem. We saw a new path forward in the innovative Jericho Horn technology. The J4 is a ‘super-tweeter’ that can deliver up to 150 dB-plus of high-frequency content.”
