Key Features

220W 5" x 7" 2way shallow component speaker system - In Phase Car Audio SXT57.1C

InPhase SXT57.1C 220 Watt 2-way Component Thin Shallow Speakers

In Phase International are constantly updating their product range with new and exciting products and this new range of shallow mount speakers is no exception.

For maximum sound and bass quality, it has to be components. In Phase component kits are amongst the best on the market, with the same technology, features and benefits used on their high quality speakers. Glassfibre cones for pure undistorted sound from pistonic action without break-up and efficient motor structures. The tweeters are again Rare Earth Neodymium designs but even more compact, with PEI domes and designed with a 360 degree ‘eyeball’ swivel mount. This means that wherever you place the speakers, they can have their crucial high frequencies directed so as to be more on-axis to your ears for best imaging and sound staging. Providing highly efficient output and clean, sweet sound with great dynamics. In Phase coaxials; for accuracy with ease.

Not only are these of the high grade that you expect from In Phase, these shallow mounts feature a low profile, so you can put them in extremely thin door panels such as Ford Focus's and many other cars that have specially built door speakers.

    Hi, will these be ok for my ford transit 2011 plate
    Is the price for a single or a pair , thanks


    Thanks for your question, in the box for the SXT57.1C is a complete set/pair of speakers, covers & cross-overs.
    They will fit or you could use some adapters (shown below) to house some 16.5/17cm round components

    Hey guys I'm aware that these will fit into my mondeo as already put 5x7s in front doors. When I purchase these where would I be able to place the tweeters while keeping them hidden

    Good Afternoon,

    The tweeters may be on show depending where you place them? On of the best pleace to mount them would be the inside wing mirror covers or on the A-Pillar. Or you could go fo 2 way speakers like the SXT5735 which have tweeters built in so they will not be on show.
