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.

Customer reviews

Buy XT6CII instead
LUKE OFFERMANNS on 05/01/2014 5 star rating

The adapters in this kit are useless because they are for the rear speakers and the front speakers screw straight in without them. Instead I suggest you save some money AND buy better quality speakers by going for the In Phase XT6CII 280W 17cm 2-way component speaker system.

    Hi I've just purchased the new Audi TT (2015) and the current sound is terrible do you have any speaker upgrades available for me that could work using the factory media installed.

    I would recommend you bringing the car into one of our stores so we can check the system and recommend the best thing for you
