Key Features

6.5" Shallow Fit 17cm 3Way, 260 Watts Coaxial Speakers with Neodymium Magnet - In Phase Car Audio SXT1735

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 InPhase 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 40W RMS to each speaker and 260W peak power . Which is fairly high for shallow mounting 17cm 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.

Great fit and great sound
MATT on 08/03/2022 5 star rating

I’ve fitted these to my Peugeot 508 as a replacement for the factory fit ones following one failing. The shallow depth of these speakers mean they clear the door drop glass which was fouling on set of bsowajers only 10mm deeper I had tried to fit. Due to the multiple mounting holes I only needed to drill one pilot screw hole for each speaker and they otherwise were able to use 2 of tge 3 original mounting points and these fit beautifully behind the original grilles in the door card ( just don’t need the included ones) . Overall impressed and will probably buy another set from this range to address a blown speaker in the other car one I know the diameter required.

Can't go wrong

At this sale price and for an upgrade to stock speakers, very happy. I'm running mine off a small 4 channel micro amp and set to high pass. This helps control the highs and mids where these speakers are best suited in my opinion. Allows me to push the speaker without distortion. The multi fit and slim depth is so handy too.

Great price & sound

    Hi I have a Mazda 2 2010, would these be a direct replacement or will adapters & brackets be needed? Thank you


    You would need the below adaptor. Also, it is recommended to use sound deadening sheets to get the most out of the speakers.
