ONKYO SL-1 (1980) - active subwoofer

Книжка с рассказом про сабвуффер ONKYO SL-1, кто и как его сделал и почему он такой хороший.  Год выпуска не указан, пишу по данным из audio-database.com там же они пишут параметры.  Судя по всему — хороший был, басы качал от души.

An active subwoofer that plays back very low frequencies from 20 Hz to 90 Hz.

The SL-1 is an acoustic transformer using a 38 cm flat passive radiator and a 20 cm driver. It is a sealed enclosure with an internal volume of approximately 80L. It is equipped with a 60W output PWM drive amplifier.

The unit is equipped with a 20 cm cone driver and a 38 cm passive radiator. By using a filter composed of these units and the front cavity to which they are connected, frequency characteristics close to band-pass characteristics are maintained and flat playback is achieved over the entire used band.

It has a built-in PWM (pulse width modulation) power amplifier with a rated output of 60W.
Because the SL-1 has a high-power amplifier built into an airtight box, special consideration must be given to internal temperature rise. The PWM method is suitable for such applications because it has less power loss with the same output than other types of amplifiers.

Книжка формата В5 на скрепках, верстка чисто японская — надо смотреть справа налево, как их журналы и книжки.
