Maintained! A popular 2-way 500Hz network. It's an essential network for 2" drivers. In addition to a 3-position attenuator, it is equipped with a high frequency boost switch. It is very effective when constructing a 2-way system with a JBL 2441 driver, etc. The sound has also become fresh due to terminal rust removal (acid washing) treatment and insulation bushings and mounting screw replacement. There is a feeling of wear and small scratches over time (Teramoto Hidehiko)
Maintenance information: 2023/12/17 maintained (terminal rust removal (pickling) treatment, insulation bushing & mounting screw replacement. ATT (SW type) contact cleaning. Reinforced so that the coil fixing inside the housing does not come off. Frequency characteristics measurement checks (~ approx. 42 kHz) were performed, and the original capacitors were continued to be used for good results. (Check input/output waveforms and balance, check sound output)
Accessories: none
Main specifications: crossover 500Hz low range 8Ω high range 16Ω high frequency level control 6/8/10dB 1.9 kg
Professional cross 800 Hz network. It's an exhilarating sound with a great vantage point. How about making a 2-way horn system with a 16 ohm unit? There are stains and rust on the main body. Serial 7293/8121 (Satoshi Yonejima)

Accessories: None
Main specifications: Impedance/bass range 8Ω, treble 16Ω crossover 800Hz high frequency boost 3-stage switching
Maintained! A rare 800 Hz/8 ohm network that doesn't arrive easily. The low frequencies are smoothly pushed out, and the clarity of the mid and high frequencies is enhanced. This network is recommended for those considering using a 2-way driver configuration. For LE175 and LE85 users You can enjoy a horn sound that is a bit different from 500Hz. Overall, there is a feeling of use over time. (TERAMOTO Hidehiko)
