Why Professionals Choose the Icom External Speaker SP-35
The SP-35 routes audio directly to where the operator needs it — a secondary control position or a workstation in a multi-operator room. The speaker handles 7W maximum input with a frequency response from Fo to 20 kHz. That covers the full audio bandwidth of Icom's LMR, P25, and aviation mobile platforms without compression at operational volume levels.
The 4 Ω impedance matches the audio output stage of IC-F5400D, IC-F5330D, IC-F5130D, and IC-A120 mobile transceivers directly — no impedance adapter required. The 2 m cable is long enough for most in-vehicle and dispatch desk installations without extension. The compact 122 × 73 mm footprint seats on a shelf, mounts to a surface bracket, or installs behind a panel opening without requiring a dedicated enclosure.
For IC-A120 aviation mobile installations in ground support vehicles or ramp operations, the SP-35 provides a secondary audio point in the cab that keeps airband communications audible during high-ambient-noise operations — engine noise, ground equipment, and jet blast all reduce the usability of the radio's internal speaker. A dedicated external speaker at operator ear level resolves this without any modification to the radio installation.
The SP-35 is the original Icom part, matched to the output stage of Icom mobile transceivers across multiple platform generations.

FAQ
Is the SP-35 compatible with the Icom IC-A120 and IC-F5400D?
Yes. Both the IC-A120 and IC-F5400D/IC-F6400D are on the official Icom SP-35 compatible products list at icomamerica.com. The SP-35 is designed as the OEM external speaker for Icom mobile transceivers across LMR, P25, aviation, and amateur platforms. For models not listed here, contact our team to confirm compatibility for your specific installation before ordering.
What is the difference between the SP-35 and the SP-35L?
The SP-35 and SP-35L share the same speaker specifications — 7 W maximum, 4 Ω, Fo–20 kHz. The SP-35L has a longer cable for installations where the radio and the speaker position are further apart. If your vehicle or console installation requires more than 2 m of cable run, the SP-35L is the better choice. Contact our team to confirm cable length requirements for your setup.
