The crossover being a vital part of a speaker it may be difficult for the end user to understand what it does, and consists of, as it cannot be seen due to the internal location within the speaker. What is the exact purpose and why are Peak´s crossovers in a superior category of their own?
The crossover separates music signal into specific frequencies for each driver, adjusts the level of the drivers together and balancing the frequency response. All Peak speakers have an integrated equalization of the impedance making the impedance curve exceptionally flat. This causes a significant advantage for the amplifier as it easily can perform as intended not troubling with unwanted heavy loads.
Peak speakers are equipped with extreme high-quality components: capacitors, coils, and resistors. Most of these parts are handmade. Each driver section has it´s designated crossover meaning that Peak speakers contain of as many crossovers as they do drivers. To avoid microphonic effects the separate parts are mounted using a special damping glue together with the finished crossover being totally separated from the driver cabinet! This crossover philosophy means that no acoustic energy can influence or obstruct the intentions of the crossover. The selection of all crossover components and further development is done through countless listening session by our engineers in close cooperation with dedicated audiophiles. The sensitivity of human hearing is outstanding and as our ears can tell differences that can´t be measured it vital to the Peak team only to complete our extreme speakers with these extraordinary “tools” we all are equipped with.
"But most important, and perhaps because of that high crossover frequency, instrumental harmonic structures, and especially the human voice, were exceptionally lifelike and coherent. I can't think of a loudspeaker
that better reproduces instrumental and vocal touches and textures. I could consistently rely on the Diablos to provide long evenings' worth of entertainment without producing boredom or fatigue. They always
invited me in and never pushed me away."
