Listening to the Motown classic Endless Love with just one 2N3053 bipolar transistor, it's 8mA collector current running through the voice coil.
What an amazing sound! It fills a room with beauty at the whole frequency spectrum.
Signal path, setup:
(Endless Love - Diana Ross, Lionel Richie, from CD) - Sony portable CD player with line out bridged to mono - Pleiades 2N3053 - Philips AD5046N - a half tiled kitchen the size of a small echo chamber
The sounds from just 1 speaker passes on or diffuses brilliantly to the other rooms too. It is also a great antidote for general low frequency building noise from machinery.
The Philips AD5046N is a brilliant, amazing speaker. With its 800Ω input impedance, full frequency range, high efficiency it is doing the most of just 8mA in class A. Class A means electrons are flowing all the time.
Pleiades concepts of schematics are open source.
