■ Lansing Front-Loaded Horn Theater System ■
This is a front-loaded horn theater system released by Lansing.
Lansing was known for its highly precise craftsmanship, and it is said that their workmanship impressed both Western Electric executives and Mr. Lansing himself.
This legendary cabinet offers an excellent balance between the high and low frequencies. Its sound quality is brilliant and well-defined, with a refined consistency that differs from other theater-specification systems.
After being exposed to the Los Angeles sun for several decades, the cabinet has developed a thoroughly dried character, yet it still retains a necessary sense of warmth and moisture. This creates an impressively rich and tenacious texture. The bass, in particular, is truly outstanding.
It is easy to understand why these systems are reportedly still used in theaters on the East Coast today.

【515 RWB 20Ω】
This model was successfully put into practical use in 1942 alongside the 288 driver, during the development of a new theater speaker system that would later correspond to the A5 system. It is considered the predecessor of the 803/416.
While the 803/416 are also high-performance units, this is an even higher-grade and rarer unit.
Diameter: 38 cm / 15 inches
Serial: 2255
Voice coil diameter: 3 inches
Magnet: Alnico V
Maximum input: 35W / 50W peak
Impedance: 20Ω
Sensitivity: 98 dB/W/1.2 m
Frequency range: 20 Hz–1,000 Hz
Recommended crossover frequency: 500 Hz
【288 RWB Hollywood 24Ω + Early Model H805 Tar Filled】
The 288 driver has a basic structure that is largely similar to the later 802 driver developed for the A7. However, the 288 was a driver used in large theater systems such as the previously mentioned A1X, so its specifications differ significantly from the 802 in many areas.
For example, the 802 has a 1-3/4 inch voice coil, while the 288 has a 2.8 inch voice coil and a more powerful magnetic circuit. The phase plug also differs: the 802 uses a double-slit structure, while the 288 uses a triple-slit structure.
By adding one more slit, it minimizes high-frequency attenuation caused by the large-diameter diaphragm and secures effective high-frequency performance.
Although the 288 driver was developed more than half a century ago, it remains an extremely well-completed driver unit with no sense of being outdated.
