Founded in 1996, the Revel company was recognized by audiophiles and specialists around the world as a manufacturer of the best acoustic systems. The company only accepts complex and expensive filters of a high order (24 dB / octave), because they are "musical", eliminate crossovers on the frequency response and do not introduce phase distortions.
Founded in 1996, the American company Revel was recognized by audiophiles and specialists around the world as a manufacturer of the best speaker systems. The company accepts only high-order filters (24 dB / octave), because they are "musical", eliminate the crossover and do not introduce phase distortion.
Many manufacturers specify detailed acoustics specifications, but it manifests itself in some ideal conditions of the home environment. All Revels sound exactly the same at low and maximum volume. This is extremely difficult to achieve with low frequencies, as they require a rise as the volume level drops.
The Performa F30 speakers, like all other speakers of this line, are individually calibrated during the production process and manually adjusted to hundredths of a decibel to meet the strict tolerances on the parameters.
All this guarantees unprecedented stability of characteristics and impeccable timbral accuracy.
High-order crossovers are implemented on selective elements with small tolerances.
In addition, there is the possibility of fine-tuning the tweeter - fine-tuning on the high frequency allows you to ensure a balance with an accuracy of up to 0.5 dB.
The cones of the Revel Performa F30 midrange and woofer speakers are made of aluminum, the surface of the diffuser is perfectly curved and smoothly connects to the speakers, the baskets of which are equipped with ribs for greater rigidity. As a result of this design, the distortion clearly visible in competitive models is reduced to almost zero in the Revel Performa F30, even at high volume levels.
