DENON DSW-101

Commentary

The newly developed P. P. D. D. system enables heavy bass reproduction.

The P. P. D. D. (Push-Pull Dual Driver) Parallel method developed by DENON is used to enable powerful deep bass playback even though it is relatively small.
The p. P. D. D. Parallel method solves this problem by attaching the edge of one of the speakers in the opposite direction so that the harmonic distortion is cancelled by each other.
In addition, since the two woofers are push-pull driven, the driving force and vibration equivalent mass are doubled, and the low-frequency reproduction range is expanded.

The unit is equipped with two 15 cm cone type woofers, and by connecting them in parallel, the effective diaphragm area is secured and the amplitude distortion of the speaker is suppressed.
This unit uses a wide rubber edge and an aluminum bobbin for improved durability and damping to reduce distortion.

The amplifier is equipped with a circuit to prevent hard clips that are unpleasant to the ear.
In addition, by adopting an original sealed type, adverse effects on sound quality due to unnecessary vibration are suppressed.

Equipped with an auto power off function that automatically goes into standby state when there is no signal for several minutes.
It returns to ON automatically when a signal is input.

The crossover frequency can be varied and a phase selector switch is also installed.

There were 2 kinds of variations, wood grain finish and black finish.
