SC-V707
Commentary

A speaker system that uses the Push-Pull Dual Driver (P. P. D. D.) method to achieve low-frequency playback that exceeds the size of the speaker system.

The SC-V707 uses the P. P. D. D. Serial method to improve low-frequency playback.
In this method, two speakers arranged back-to-back amplify in the direction that cancels out each other's non-linearity, thereby reducing the harmonic distortion that occurs when the speakers are driven. In addition, since the speakers are arranged back-to-back, the magnetic flux leakage can be surely shielded and the magnetic shielding effect is high.
In addition, by optimizing the design of the speaker cabinet, peaks and dips in sound pressure frequency characteristics due to phase interference of the speakers are prevented.

Two 12 cm cone type woofers with a non-magnetic frame are installed in the range.
For the edge, rubber edge is adopted to suppress excessive squeal, and in combination with coating cone and non-conductive bobbin, sound quality is improved.

A 2.5 cm soft dome type tweeter is installed in the high range.

OFC internal wiring materials and high-sound condenser are used for the network.

The enclosure uses a bass reflex system.
There are 2 types of exterior variations, wood grain finish and black pear finish.

Equipped with a 120 mm pitch nut on the bottom surface that is compatible with separately sold stands and commercially available wall hanging fittings.
In addition, we have adopted a large gold-plated brass scraping terminal for banana plugs.

There was a speaker stand sold separately.
