About the Harmony brand

The Italian brand Harmony was born in the 80s together with the first home speakers produced by the Italian hi-end manufacturer ESB Audio. Car speaker production began in the 1990s with a wide range of products that combined high sound quality with a significantly lower price point than ESB Audio products. And that was the main mission of the Harmony brand - to provide a high standard of sound quality with faithful reproduction of the entire sound spectrum, superior processing and all this at a more affordable price. The same applies in 2022, when ESB Audio decided to create a new Harmony product line. This includes component and coaxial speakers, a subwoofer, subwoofers under the seat, and amplifiers with a DSP processor at a very affordable price are worth mentioning. More interesting high quality products will follow under the sophisticated control of parent company ESB Audio.

RMS power of the subwooferThe RMS power of an active subwoofer is the constant power that the active subwoofer can play over a long period of time. We recommend following this value. The RMS power of active subwoofers is taken as the RMS power of the integrated amplifier, which in most cases is slightly undersized, which guarantees protection against subwoofer burning.	120 W
Maximum subwoofer performancePeak performance or Max. power that an active subwoofer can play for a moment (approx. 0.5 s), for example when percussion instruments are struck in a recording. But it is not as important a parameter as the RMS power.	240 W
RMS power of the amplifier	4 x 35 W RMS
Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers.	AB

Cabling included in the packageSome active subwoofers have complete wiring included in the package. In the event that the package really includes complete wiring for connection, we mark the parameter as "yes". If the wiring is not included, it must be purchased.	Ne
Remote control included in the packageSome models of active subwoofers also have wired remote controls in the package, which on the one hand connect to the active box, and on the other hand you have a potentiometer that you can place anywhere in the cabin. A common place to place the remote control is under the steering wheel. The advantage is the regulation of power, and therefore volume, depending on driving conditions and the mood of the crew in the car.	Ano
