In Phase Car Audio XTC17.2CF 250W 17cm 2-Way Rotary Tweeter Car Door/Shelf Speakers

Tweeter Coaxial Car Speakers Coaxial Car Speakers

Buy on Amazon Find on eBay

COAXIAL DESIGN - Coaxial speakers are also know as full range speakers. As they are two way (using a two speakers rather than one) you will experience a more detailed quality sound than their dual cone counterparts. The tweeter at the centre of the cone allows higher end frequencies (treble) to be distributed out from a single point thus giving a more precise delivery. This also does not require a separate crossover to fit them as it is built in.

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

MEDIUM TO HIGH POWER - Up to 75W RMS to each speaker and 320W peak power for both. Which is high for a 17cm speaker! These speakers can be run on your headunit or via a separate amplifier. However, when using with power amps we recommend to use the subsonic feature on the amplifier to reduce the subsonic frequencies as this will reduce distortion and improve bass as well as the overall listening experience.

EASY INSTALLATION - Comes complete with all cables, fixings and instructions

BRITISH DESIGN - All In Phase SPX, XTC and SXT speakers are all designed in the UK utilising over 30 years of audio experience to create a sound that is right for you.
