DENON SC-E727

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-E727 uses the P. P. D. D. Serial method to push and pull two woofers to improve low-frequency reproduction by lowering the lowest resonance frequency.
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 14.5 cm cone type woofers are installed in the low range, and 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 has a wood finish with rounded corners.

The speaker terminal uses a banana plug terminal that is gold-plated brass machined.
It can also be used for bi-wiring.
