About the ESB Audio 1.10SD4
From our tech experts at CEN
An ESB Mille Series 10 inch subwoofer, 4 ohm, handling 250w RMS.
Who it suits
Drivers building a sound-quality system where the bass has to integrate with a capable front stage rather than dominate it. ESB is an Italian brand with a following among people who care more about how a system images than how loud it goes.
Our tech experts advise
Enclosure volume and tuning decide most of what you hear, and a driver like this deserves a box built to suit it rather than something off a shelf. We build enclosures at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.

A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.

A: It has a mounting depth of only 95 mm, so it suits shallow enclosures and installs where space is tight.

A: ESB optimises the 1.10SD4 for a sealed box of about 22 litres.
