A very impressive pair of Ray Audio RM-7V horn speakers with an out of this world Diatone D-80M subwoofer !
The D-80 which overly adopted the large-sized unit (80cm), is a woofer system for Hi-Fi systems.
The honeycomb construction corn of Diatone tradition is adopted as a unit.
In order to heighten the ability of this diaphragm further, the aramid fiber which unites and has a high specific modulus and a moderate internal loss in skin material was adopted, and it has completed as an aramid honeycomb diaphragm.
Furthermore, the high resolution pile low-pitched sound play with a quick transient response is enabled by adopting a high-heat-resistance voice coil and a powerful magnetic circuit.
In order to also make the output of audio amplifier fully drive, it is the high efficiency design of 100 dB/m.
More than 40yeas ago, I was invited by Mitsubishi Electric UTUNOMIYA
factory, to make a presentation of their huge Speakers, like, this 80cm dia, and 150cm
dia.
After they started, some glasses of factory around 300m far from the listening room, were broken, because of this low frequency by 150cm dia. speaker.
