ESB Audio 1.10SD 10" Shallow Dual Voice Coil Subwoofer
More bass with less space. Italian engineering meets ultra-compact design.
The ESB 1.10SD is a 10-inch shallow subwoofer engineered to deliver serious bass performance in an ultra-slim profile—only 95mm deep. Designed and built in Italy since 1969, ESB combines cutting-edge motor technology with a powerful 40.5 Oz ferrite magnet to punch out 500 watts of peak power without sacrificing sound quality or taking up valuable trunk space.
Why the 1.10SD?
Space is precious in most vehicles. The 1.10SD solves that problem with an innovative shallow design that fits tight installations—under seats, in door panels, or compact trunk setups—while delivering the bass response you'd expect from a full-size sub. The polystyrene cone with long-throw rubber surround ensures clean, controlled bass across the entire frequency range, while the dual voice coil design gives you wiring flexibility for any amp configuration.
Key advantages:
- Ultra-slim 95mm depth – Fits tight spaces without compromising performance
- 500W peak power handling – Serious output from a compact package
- Dual voice coil options – Choose 2+2Ω or 4+4Ω for flexible amp matching
- Italian engineering – 55+ years of ESB audio heritage and quality
- Long-throw design – Polystyrene cone with rubber surround for extended bass
- Optimized for sealed boxes – Recommended 21-22L sealed enclosure for best results
Built for Real-World Installs
The 1.10SD is purpose-built for vehicles where space is limited but bass quality isn't negotiable. Whether you're upgrading a compact car, adding bass to a truck under-seat install, or fitting a subwoofer into a tight custom enclosure, the shallow profile doesn't compromise on performance. The 40.5 Oz ferrite magnet and 2"/51mm voice coil deliver controlled, articulate bass that integrates seamlessly with your front speakers.
Installation-ready features:
- Dual voice coil design for flexible wiring configurations
- Optimized for 21–22L sealed enclosure (MDF thickness 18–19mm recommended)
- Polystyrene cone for durability and clean bass response
- Long-throw rubber surround for extended excursion
- Recommended amplifier power: 100–250W RMS
- Thiele & Small parameters provided for custom enclosure design
