Hertz SPL Show SX 690 H NEO

Hertz SPL Show SX 690 H NEO - 6x9" Coaxial Speaker Set with Neodymium and 130 W RMS

The Hertz SPL Show SX 690 H NEO is a 6x9-inch coaxial speaker set designed for high sound pressure levels and clear reproduction across the entire frequency range. A 1.4" dome tweeter and a 1" super tweeter handle the upper frequencies, while the water-repellent pressed paper cone provides punch in the bass. Neodymium N38 H as magnet material and double-layer copper voice coils ensure high power handling and stability. With 130 W RMS, 94 dB efficiency, and 4 Ohm impedance, the SX 690 H NEO is ideally suited for powerful car hi-fi setups. Each chassis weighs 1.69 kg – robust yet compact.

Installation & Compatibility

The set is designed for 6x9" cutouts and is suitable for doors or rear decks if you desire high sound levels and stable high-frequency resolution. With 4 Ohm impedance and 94 dB efficiency, it performs well with a head unit, but clearly benefits from a powerful amplifier around 130 W RMS per channel. The water-repellent cone is advantageous in vehicle areas with increased humidity.
