DENON/COLUMBIA VS-520
Price unknown (1 unit, around 1970)
Commentary
A 3-way speaker system with a special enclosure.
The unit consists of a 30 cm woofer unit with collagen fiber, a 12 cm cone type unit, and a two way structure with a horn type tweeter with a light alloy diaphragm.
The enclosure is made of a special material that is not simply thick and heavy. The internal loss of the material suppresses resonance phenomena in the audible frequency band. The large mass of the material, coupled with good sound insulation characteristics, has no effect on low-frequency speakers and improves intermodulation distortion in the mid - and high-frequency range.
Also, by increasing the thickness, it becomes a very heavy enclosure of about 60 kg.
