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

Component Design
Component speakers offer higher quality sound than their coaxial counterparts. The tweeter mounted to the dash or A-pillar allows higher end frequencies (high notes) to be distributed out

Carbon Fibre Cone, Butyl Rubber surround and Die Cast Aluminium Chassis
Carbon Fibre is a high mechanical strength fibre which has many applications. Used in car bodies, speakers, wheels, this material will offer endurance as well as high end performance for a speaker. The chassis is built for endurance, the construction of this speaker holds well and lets the speakers reach performance levels above the rest.

High Power
These speakers allow up to 360W Watts Peak to each speaker and 120W RMS power. Which is ridiculous for the application, but this kit isn't built for the amateur audio fan.

We also would recommend fabricating some MDF baffles instead of plastic trims to fit the speaker in. This is due to how much power, vibration and weight of these speakers. The MDF will also absorb and distribute the sound-waves and vibrations properly so you will have a distortion and rattle free experience.
