DENON SC-A33

Commentary

A compact speaker system equipped with a direct-drive Super Tweeter.

Two 8-cm cone type woofers are mounted in the lower range and are driven by the P. P. D. D method.
In the conventional method, when a large amplitude is received, the linearity of the vibration system such as the edge is lost, causing distortion in the reproduced sound. In this method, by attaching one of the speaker edges in the opposite direction, the harmonic distortion is cancelled out by each other, resulting in clear reproduction with less distortion.
Glass fiber cone is used for the diaphragm.

A direct-drive Super Tweeter is installed in the high range.
In this system, the voice coil bobbin and diaphragm are integrally molded, so that the driving force of the voice coil is transmitted to the diaphragm without using any adhesive, so the response is extended to the ultra-high frequency range. In addition, the equalizer suppresses wave surface disturbance and realizes smooth sound emission.
Neodymium magnet is used for the magnetic circuit.

Non-magnetic frames are used in all units.

The network section is designed with attention paid to directivity and is optimized to obtain uniform sound pressure / phase response over a wide area in order to increase the sweet spot. This makes it easy to set up multi-channel speakers and enables each person to enjoy multi-channel audio when watching a large number of people.

The front baffle uses a highly rigid 3-D processed round baffle to eliminate diffraction effects and unwanted resonance.
A bass reflex system is used for the enclosure.

A large speaker terminal with gold-plated brass shavings is adopted.

It has a 60 mm pitch nut mounted on the bottom that corresponds to the separately sold speaker stand and wall mounting bracket.
In addition, a hook for hanging on the wall is equipped on the back.

Comes with a natural cork spacer, allowing sound radiation from the back to diffuse smoothly when using the wall hook.
It also comes with a natural cork foot.

There were two variations in the finish of the exterior.
