Key Features

13cm shallow mount 3way coaxial speakers 230 watts - In Phase Car Audio SXT1335

In Phase are proud to launch the newest series of SXT speakers, a no comprise design giving true performance from minimum amounts of power so great for those who needs speaker upgrades without adding amplifiers. Pushing the inventiveness of design In Phase have used an inverted magnet to make the new series shallow mounting dept, allowing for easy installation in most cars.
Using 3-Way speaker combination gives for translucent highs while our Poly-Mica coated cone with Butyl rubber surround produces effortless deep rich accurate bass. 

These speakers are an essential upgrade for any car audio system. Complete with discreet grills, speaker cable and all speaker fixings for a no stress installation.The perfect speaker upgrade in any car.

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.

Coaxial Design

Coaxial speakers or full range speakers as they are also known as offer higher quality sound than their dual cone counterparts. The tweet at the helm of the cone allows higher end frequencies (high notes) to be distributed out. This also does not require a separate crossover to fit them.

Poly-Mica coated cone, Butyl Rubber surround and Aluminium Chassis

Poly-Mica is a budget friendly, plastic speaker cone. When combined with Butyl Rubber surround, a high quality spider and decent shallow magnet, you have a budget friendly shallow mounted speaker which produces beautiful high notes and resonant bass notes.

Low to Medium Power

These speakers allow up to 35W RMS to each speaker and 230W peak power . Which is fairly high for shallow mounting 13cm speakers! These speakers can be run on your headunit or via a separate amplifier. These speakers are designed for tight spaced doors or areas. They do no require high power to produce beautiful sound.

Got more than I thought
Dr on 10/05/2020 5 star rating

I did not expect alot from these little speakers, they are light and small.Once fitted in my wife's car she noticed the difference "hey my radio sounds so much better" They are really good little speakers.

Your team at the Garratt lane branch recommended these for my Mercedes Vito. These were very easy and simple to installed. I cannot believe the difference these have made i am still using my factory radio. tweeter is very sharp and crystal. I would be adding an under seat subwoofer very soon to compliment the whole system.
