•HPF (high pass filter): Cuts the lower frequencies and allows the higher frequencies to pass.
•LPF (low pass filter): Cuts the higher frequencies and allows the lower frequencies to pass.
•Slope: The level change (in dB) for a frequency change of one octave.
•The higher the slope value, the steeper the slope becomes.
•Adjust the slope to FLAT to bypass the HP or LP filters.
•Do not use a tweeter without the HPF on or set to a low frequency, as it may cause damage to the speaker due to the low frequency content.
•You cannot adjust the crossover frequency higher than the HPF or lower than the LPF.
•Adjustment should be made according to the recommended crossover frequency of the connected speakers. Determine the recommended crossover frequency of the speakers. Adjusting to a frequency range outside that recommended may cause damage to the speakers.
For the recommended crossover frequencies of Alpine speakers, refer to the respective Owner’s Manual.
We are not responsible for damage or malfunction of speakers caused by using the crossover outside the recommended value.
About IMPRINT
VISION VS. REALITY
All good music starts as an artist’s vision. After countless hours of rehearsing, recording and mixing, that vision is ready for us to hear on discs, radio and other media. But do we hear it as the artist created it? Unfortunately, the reality is that we are almost never able to listen to it in the exact way the artist intended. Especially when we are listening in a car.
CARS ARE TERRIBLE LISTENING SPACES
Car interiors are full of materials that obstruct and degrade sound quality. For example, windows amplify and reflect high frequencies. Seat and dashboard coverings change certain frequencies. Carpets absorb and suppress mid frequencies. Graphic and parametric EQs are only partial remedies for these problems. In addition, the speakers are not located at equal distances from listeners, creating an unbalanced, uncentred sound stage. Time correction can help fix this, but only for one listening position.
