A touch panel controlling the whole vehicle
Signaling, lighting, power and temperature on one screen. Natively synchronised with EMCORE, not a universal off-the-shelf panel.

Siren speakers for emergency vehicles
The speaker is what actually determines the siren's reach — the amplifier delivers power, but the driver turns it into sound. THUNDER compression speakers (100 W RMS, 11 Ω, 122 dB @ 1 m) are designed and tuned for EMCORE amplifiers: an in-house voice coil, a neodymium motor and ferrofluid in the gap.
Siren speakerTHUNDER TS-100F
Louder. Cleaner. Farther.
A 100 W siren speaker rated IP66: an in-house voice coil, a neodymium magnet and ferrofluid cooling — an acoustic path tuned to the 500–1800 Hz band of EMCORE amplifiers.

Siren speaker (round housing)THUNDER TSR-100F
Louder. Cleaner. Farther.
The round, aluminum version of the 100 W siren speaker — the same acoustic path as the TS-100F, in a format for builds that demand a precise fit.

Low-frequency speakerREZON SPEAKER
The band you feel.
A 100 W low-frequency speaker in a polyamide housing, with a polypropylene cone resistant to engine-bay conditions. A 180–500 Hz band — below the reach of classic siren speakers; tuned as a set with the REZON modules.

THUNDER TS-100F and TSR-100F
TS-100F (ABS + aluminum housing, IP66) mounts behind the grille or on the bumper on the A2 L-bracket. TSR-100F, in a round aluminum housing, is picked for builds with limited space — identical acoustics, without the IP66 rating. Both are 11 Ω / 100 W speakers (150 W peak), 500 Hz – 5 kHz band.
Four engineering decisions, not marketing
An in-house voice coil (full control of power handling), a band tuned to the amplifier, a neodymium magnet (higher SPL at the same current draw) and ferrofluid cooling the gap — a neodymium siren speaker that stays clean without power compression in continuous duty.
REZON low-frequency speaker
The dedicated low-band driver: 100 W RMS (200 W peak), 180–500 Hz band, polypropylene cone, 8 Ω impedance — designed for the REZON / REZON PLUS+ modules.
E20 · ECE R65 class 2 · ECE R10 type approvals — every configuration tested in our own laboratory.
Frequently asked questions
Answer not here? Call us — an engineer picks up, Mon–Fri 7:00–15:00 (CET).
For EMCORE ULTRA and MICRO we recommend THUNDER TS-100F (behind-grille/bumper mounting, IP66) or TSR-100F (compact round housing). The 11 Ω impedance matches the output stage of Emertronic amplifiers.
We will match a configuration to your vehicle.
