Zero Loss High Power Device Improve Spatial Output Of Speakers

Aaudio equipment service shop proprietor in Singapore has probably invented the world's first zero loss device to improve the spatial quality of any loudspeaker.

The device connects between the audio amplifer output and the speaker. Two such device is needed for a sterophonic setup.

A quick look at the device indicates some kind of bandpass filter with peak clamping.

The use of a vacuum tube is interesting. The heating filament of the vacuum tube seems to be wire in series with one of the amplifier output terminal, probably providing some kind of peak power clipping, the negative resistance of the heating element could have contributed to the delay in the "attack" of any loud sound.

Not the use of the sticks, probably to stiffen the hook up wires to prevent parasitic capacitance.

A hearing demo by the shop owner does present a dramatic quality improvment in sound.
