Vintage Kenwood CM-7ES 70W 8 Ohm 2 Way Speakers

One metal grill pushed in. Some marks and wear. No box or manual.

Details from internet as follows;

A 10 cm cone type woofer is installed in the low range.

Carbon is cross-woven into the diaphragm as long fibers and bonded with a special resin. The diaphragm has high elasticity and high rigidity, greatly improving sound propagation characteristics, and at the same time, it is finished into a diaphragm with moderate internal loss.

This increases the crossover frequency to 5 kHz, which increases the high-frequency range of the woofer and improves the amount of important mid-range information.

A 1.9 cm dome type tweeter is installed in the high range.

Polyetherimide, which has properties between hard and soft domes, is used as a 100 μ ultra-thin plate for the diaphragm. This greatly improves transient characteristics and directivity.

In addition, the dome and the edge are integrated into an inner edge type to prevent the deterioration of transient characteristics due to the elasticity of the adhesive, and energy from the voice coil is directly converted into air vibration.

Each unit has an anti-magnetic design that employs a cancel magnet.

This also reduces the magnetism across the coils of the network.

Low-distortion type capacitors are used in the network.

In addition, the network coils for the woofer and the tweeter are arranged orthogonally, and one point grounding is adopted to eliminate harmful crosstalk.

The enclosure is made of special polypropylene to ensure adequate internal loss while thoroughly suppressing resonance.

The back has vertical and horizontal wall mounting holes, and the bottom has female screws that can be used for various types of commercially available mounts.
