Hertz SPL Show SX 690 Neo.1 - 6x9-inch Hi-SPL Coaxial Loudspeakers for Maximum Levels
The Hertz SPL Show SX 690 Neo.1 is a 6x9-inch Hi-SPL coaxial loudspeaker designed for loud, clear in-vehicle reproduction. The mid-high unit combines a 1.4-inch dome tweeter with a 1-inch dome super tweeter and utilizes a resettable solid-state protection circuit. The water-repellent, UV-stable paper cone and compact special Neodymium N38 H motor ensure high efficiency with a shallow mounting depth. Ideal for doors and rear decks when you are looking for high levels and intelligibility â even in open-top vehicles or noisy environments.

Installation & Compatibility
The SX 690 Neo.1 fits many 6x9-inch mounting locations in doors and on the rear deck. With 4 Ohm impedance and 94 dB efficiency, it performs well with solid head units, but significantly benefits from a powerful amplifier delivering around 100â130 W RMS per channel. The robust, water- and UV-resistant construction makes it a great choice for demanding environments and SPL-oriented setups.
