DENON SC-C777SA

Commentary

A next-generation audio center speaker system capable of playback up to 200 kHz.

Two 12 cm cone type woofers are mounted in the low range and are driven by the P. P. D. D. (Push-Pull Dual Driver) Parallel method.
In the P. P.D. D. PARALLEL method, the two side-by-side woofers are designed so that their edges are opposite to each other, thereby canceling out harmonic distortion and realizing low-frequency reproduction with less distortion. In this method, the harmonic distortion is improved by 6 dB in the region where the amplitude of the speaker cone increases near the lowest resonance frequency. In addition, the driving force and vibration equivalent mass are doubled by push-pull driving of the two woofers, and the low-frequency reproduction range is expanded. The woofer diaphragm is equipped with lightweight and highly elastic glass fiber.

A 2.5 cm soft dome type tweeter is installed in the high range.
This unit uses a neodymium magnet for the magnetic circuit.

A leaf-type Super Tweeter is installed in the super high range.
A newly developed ultrathin sandwich polyimide film is used for the diaphragm, enabling playback at frequencies up to 200 kHz. This allows playback at frequencies higher than 20 kHz, which is a major feature of next-generation audio, and at frequencies higher than 20 kHz.

Each unit uses a non-magnetic frame to eliminate the influence on the magnetic circuit, thereby reducing noise turbidity.

The network section is equipped with a newly designed crossover network.
In order to increase the sweet spot in multi-channel playback, this network pursues wide-area and uniform directional characteristics, so that each person can enjoy multi-channel audio even in the trial listening of many people.

The front baffle uses a 3-D processed baffle to minimize the mounting surface of the unit and eliminate the diffraction effect caused by the end face of the baffle. The baffle material uses 30 mm thick MDF to firmly support the large vibration of the woofer and suppress unnecessary resonance.
The enclosure uses a bass reflex system.

The rear terminal uses a large brass machined gold plated terminal for extremely thick cables and banana plugs, as well as bi-wiring.

Comes with a stand from which you can choose 2 installation angles.
This stand can be adjusted to the set viewing position.
In addition, a cork foot is attached as an anti-slip.
