New York (September 8, 2005)–ISP Technologies has been spreading the word about its LT1 and LT2 speakers, a 3-way active speaker system with reportedly high output and low distortion that achieve coverage said to range from 60 degrees vertical x 90 degrees horizontal, up to 70 degrees vertical x 120 degrees horizontal.
The company feels that “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, our 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 we call 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 by ISP, as that option 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, was designed with the expectance that it would provide wider, cleaner, more detailed midrange coverage than 2-way designs. ISP states that 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 LT1 and LT2 are specifically designed for flying with small vertical dimension inside venues of 50 seats up to 600 seats. The boxes have been used by ISP and various contractors in houses of worship, clubs, roller rinks and other venues.
