The Icom SP-35L is a high-performance compact external speaker designed specifically for Icom mobile transceivers, base stations, and professional repeaters. As the extended-cable version of the popular SP-35, it features a 6-meter (19.7 ft) cable run that enables a clean, convenient, splice-free installation in large vehicles, commercial vans, trucks, heavy equipment, and radio shacks where the radio unit is mounted under a seat, in the trunk, or inside communications racks.
With a nominal impedance of 4 ohms, a rated input power of 5 W, and a maximum input capacity of 7 W, this speaker delivers clear, punchy, and articulate voice reproduction. Engineered to overcome cabin road noise, diesel engine rumble, or heavy machinery noise, it ensures maximum audio intelligibility across analog, digital IDAS/dPMR/NXDN, P25, and satellite communications.
Key Advantages
- Extra-Long 6-Meter Cable: Allows the speaker to be positioned near the driver or operator while the radio remains discreetly installed in the trunk or under seats.
- Optimized Audio Performance: 7 W maximum input power (5 W rated) to project crisp voice audio above ambient cabin noise.
- Compact, Ergonomic Design: Compact dimensions of 122 x 73 x 46.5 mm allow easy mounting on dashboards, pillars, or vehicle headliners.
- Broad Icom Compatibility: Standard connector compatible with amateur radio transceivers, IDAS commercial fleet radios, repeaters, and satellite PTT terminals.
- Stable, Secure Mounting: Rugged 390 g housing engineered to absorb continuous mechanical vibration during on-road and off-road driving.
Recommended Applications
Heavy Transport, Commercial Delivery Fleets, and Buses
The 6-meter cable length effortlessly bridges the distance between a hidden transceiver installation and the driver’s operating position.
Emergency Vehicles, Police, and Civil Protection
Improves reception of priority voice traffic in noisy environments where sirens and traffic interfere with the radio’s built-in speaker.
Base Stations, Communications Rooms, and Repeaters
Enables clear voice channel monitoring in rack cabinets and operating desks with direct front-facing acoustics.

Frequently Asked Questions
How does the SP-35L differ from the standard SP-35?
Both speakers share the same enclosure, acoustic power, and impedance, but the SP-35L comes factory-fitted with a 6-meter cable (compared to the standard SP-35’s 2-meter cable), removing the need for extension cables or wire splices in large vehicles.
Can I use this speaker with radios requiring 8 ohms?
The SP-35L has a nominal impedance of 4 ohms, which is the recommended standard for the vast majority of Icom mobile transceivers. It operates smoothly and delivers optimal volume with any radio equipped with a 3.5 mm external speaker jack designed for 4 to 8-ohm loads.
