This combination is powerful and highly durable, making it suitable not only for regular home use, but also for restaurants, bars, schools and conference halls.

1) AQ M4D

Two-channel amplifier with 2 x 50W. The amplifier has compact dimensions of 19 x 28 centimetres, its aluminium base is also a heat sink to which heat is transferred from the electrical circuits. The internal power supply is provided by a massive toroidal transformer of up to 120W. The amplifier has 4 inputs with cinch - RCA connectors, located on the rear panel.

There are two multi-function controls on the front panel and a backlit display under the black acrylic. In the active state, the display subtly illuminates the black surface, while in the off state the face is pure black, possibly with a light dot indicating the Stand-by state. Compared to its predecessor, the AQ M3, we managed to significantly increase the signal-to-noise ratio.
In its price class, the amplifier surprises with high sound quality.
The remote controls input switching, volume, display intensity, bass/treble correction, left/right balance, MUTE and stand-by.

2) AQ Tango 93

A two-way bookshelf loudspeaker for maximum versatility. Thanks to the bassreflex located on the front, the speaker can be placed up to the wall, or a bracket can be screwed onto the rear wall.

The Tango 93 is perfect for smaller living rooms, but it also has its place in many bedrooms, children's rooms, classrooms and offices.

The soundboard is made of MDF panel with a foil finish in a faithful imitation of wood. The rigid sound box houses a 1" VIFA tweeter with neodymium magnet and fabric calotte and a 6" midrange driver with lightweight and rigid aluminium diaphragm in a solid steel basket.

Inside is a 6.6 dB/oct woofer voice coil wound from 1 mm diameter copper wire on an air core. This eliminates the oversaturation of the voice coil common in inexpensive loudspeakers at higher power levels. All internal connections are hot soldered, including the connection to the spring terminal on the rear panel.
