Waterford, MI (August 3, 2005)–The ISP Technologies LT1 and LT2 speakers are a 3-way active speaker system with high output and low distortion that place patented technology within the reach of any venue. These boxes achieve coverage that range from 60 degrees vertical x 90 degrees horizontal, up to 70 degrees vertical x 120 degrees horizontal.
Because all speakers are within one cabinet, the LT1 and LT2 are more affordable because only one set of flying hardware is required. Secondly, each sub-box (or cell) provides wider vertical coverage than standard line array boxes, requiring fewer cells. Third, ISP’s high current D-CAT amplifiers are specially built for our systems to further reduce cost, since one amplifier module can provide 3 frequency bands of amplification plus electronic crossover, a configuration called TRIPOWER.
The LT1 and LT2 speakers are designed to be flown from the ceiling in a permanent installation. They can be used by themselves or with subwoofers. When used without subwoofers, the ‘S’ option is recommended, which uses a special woofer with larger excursion capabilities and lower resonance for higher output at low frequencies.
The 3-way design, with an 8-inch midrange, which is phase-aligned with the high frequency driver, allows for wider, more detailed midrange coverage than 2-way designs. It also results in better low-frequency response since the woofer can be optimized for LF performance, and off-loading the midrange duties results in lower power compression.
The standard high frequency driver is a 2-inch voice coil, titanium diaphragm unit with excellent frequency response. The ‘XF’ option specifies an upgraded HF driver with polyester diaphragm, higher sensitivity, and smooth and extended frequency response. The high frequency horn features a dispersion of 90 degrees horizontal by 70 degrees vertical with coverage from the first row to the last–much more than the 40 degree vertical dispersion typical of most boxes, since when a speaker is flown the required vertical dispersion increases. When ordered in pairs, they are furnished in mirror-image sets. Standard with the system is a separate 3-channel, 1000 Watt rms amplifier/electronic crossover that is specifically designed for use with the speaker and eliminates the necessity for a digital processor. This amplifier features ISP’s patented DCAT high-current amplification technology and a cooling fan that automatically switches on when needed.
The LT1 and LT2 are specifically designed for flying with small vertical dimension and slanted top to maximize sight lines. These boxes are suitable for venues of 50 seats and up to 600 seats and have been used by ISP and various contractors in Houses of Worship, Clubs, Roller Rinks, virtually anywhere a high-fidelity speaker with low vertical profile is needed.
