Key Features

In Phase Kevlar Cone 2 Ohm Dual Voice Coil 1200W Peak Power Subwoofer - In Phase Car Audio XT-10

Just because it’s small don’t discount it. The NEW In Phase XT range is the second generation of the XT series subwoofers. With some huge improvements to the already fantastic XT series these 2nd gen XT subs really need to be heard and handled to appreciate the true quality within.

Passengers will be blown away and left questioning whether you’ve equipped the boot with a 12 or 15-inch woofer once they’ve heard this combination slam, subtlety and immediacy of bass response.

For tight, punchy, melodic bass there’s no need to listen elsewhere.  If you actually want musicality rather than outright soul destroying, window rattling, this 10-inch could be the perfect woofer for the job. 

British Design

All In Phase audio products are designed in the UK utilising over 30 years of audio experience to create a sound that is right for you.

Enclosure Type Subwoofer

This sub is designed to be installed in an enclosure sealed or bass reflex enclosure will suffice. Open air installs can reduce power output.

Bass Reproduction

This In Phase sub offers superb bass reproduction using high quality materials. When using the right enclosure and amp, you could be hitting sub 40Hz!


The In Phase XT Series subwoofers use a Kevlar Cone technology which is far more dense than traditional paper/polyprop cones allowing the sub to endure more power. The 90oz magnet keeps the sub flexing and pushing bass waves out to a higher standard.

Power output

This sub is build for a perfect balance of SPL and SQ. So it offers a humble 350W RMS power output and 1000W Peak Power output.

Blown Me AWAY
Bass Mad on 02/05/2020 5 star rating

I replaced my old Alpine SWR 10 subwoofer with this In Phase one, budgets are low! I honestly did not expect much from this but OMG....this thing is simply Breath Taking. I was firstly impressed with the build quality, very well built. I just used the old box of my Alpine. I did not expect what I got, straight out of the box this woofer was almost twice as loud as my old Alpine on the same amp and no other changes made. Awesome subwoofer easy worth double what I paid.

Just fitted the Xt10 into my Mercedes c220 and its blown me away. Serious bass from such a small woofer.
