In Phase XTC6CX

In Phase have launched the new XTC series, sticking with our heritage we have continued to use our Famous Glass Fibre Woven Cone, giving for a more rigid and stronger cone without the additional weight producing a faster and more powerful bass response regardless of the power.

We have kept our rotary tweeter design to allow a more tailor sound stage inside your car by adjusting the tweeter to the required listening angle the listen can enjoy crystal clear sound even when the speaker is position at the bottom of the door.

Power handling and efficiency have been improved so you get more sound from your audio system.

Powered coated dampener speaker chassis helps to reduce the distortion from the speaker chassis thus improving the focus of the sound and giving more detail in the sound stage and focus. Rubber boot design helps to wrap the speaker magnet protecting it from the elements as well as absorbing vibrations. Cosmetically finished to perfection this speaker not only is beautiful to listen to is beautiful to look at.

Overall you will be impressed with the New XTC speaker line up from In Phase, happy listening.

  • Question: 07 November 2015
    Car: Vauxhall Astra - 2007>

    Do I have to use that box thing? Or can I just do a straight swop on the tweeter and speaker? No intention of getting an amp at all. The more info the better please. Thanks


    You will need to use the Xovers. Otherwise you will end up damaging the speakers.
