Question: 02 May 2017

Car: BMW Mini (R56) - 2001-2006 -

Hi does this product have a built in high pass filter?


Hi, Thanks for your question, this tweeter does not have a high pass filter, it will play high frequency as this is what it is meant for. When used in conjuction with a crossover, they are used as part of an audio crossover to direct high frequencies to a tweeter while attenuating bass signals which could interfere with, or damage, the speaker.
