The ISP Technologies LT1 speakers are a 3-way active speaker system with high output and low distortion. The LT1 speakers are designed to be flown from the ceiling in a permanent installation. They can be used by themselves or with subwoofers.
The 3-way design with an 8 midrange which is phase-aligned with the high frequency driver allows for wider, cleaner, 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 voice coil, titanium diaphragm unit with excellent frequency response. The XF option specifies an upgraded HF driver with polyester diaphragm, higher sensitivity, and exceptionally smooth and extended frequency response. This driver is possibly the most hi-fi sounding high frequency compression driver available! The high frequency horn features a dispersion of 90° horizontal by 70°vertical. This is much more than the 40° vertical dispersion typical of most boxes, since when a speaker is flown the required vertical dispersion increases. The LT1 will provide high frequency coverage from the first row to the last in nearly every situation. When ordered in pairs, they are furnished in mirror-image sets.
Standard with the system is a separate 3-channel, 600-Watt rms amplifier/electronic crossover that is specifically designed for use with the speaker. This amplifier features ISPs patent pending DCAT high-current amplification technology. A cooling fan automatically switches on when needed.

LT2- Description
The ISP Technologies LT2 speakers are a 3-way active speaker
system with high output and low distortion. The 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, cleaner, 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 exceptionally smooth and extended frequency response.
