Marantz LS-30V

Commentary

A setting-free type speaker system that employs a coaxial unit.

The unit uses a 10 cm coaxial type unit.
By co-locating a 10 cm cone type woofer and a 3.2 mm semi-dome type tweeter, each with an independent magnetic circuit, excellent sound image localization is obtained.
The magnetic circuit uses a magnet shield system with double strontium ferrite magnets, and is designed to prevent magnetic fields.

In the woofer section of the coaxial unit, the cone is supported by a unique inner edge suspension, and large amplitude can be obtained without losing linearity, and at the same time, harmonics of the drive system can be suppressed successfully.
In addition, the high heat-resistant copper preventive coil and aluminum alloy bobbin improve the input resistance.
In addition to the aluminum die-cast frame, an aluminum die-cast and tweeter post is used to fix the tweeter.
The tweeter has sufficient strength and internal loss to suppress unwanted resonance.
The diaphragm is made of PEI (polyetherimide) film with backward heat, and the voice coil is wound directly on the diaphragm to reduce transmission loss.
A strontium magnet is used in the magnetic circuit, and a magnetic fluid is inserted into the gap to control the low-frequency characteristics of the tweeter and improve the heat radiation efficiency.
In addition, a wide range of directional characteristics is obtained by a specially designed equalizer.

In the enclosure, even the bass reflex port is integrated to suppress unnecessary sound.

It comes with a multi-stand and can be installed freely.
