The Hertz HTX8HFG is an 8" (200mm) marine tower speaker delivering 200W RMS and 400W peak power at 4 ohm, with a sensitivity of 98dB SPL. Built around a common motor compression driver with an FEM-optimised waveguide, it projects full-range audio clearly at distances of 100 feet and beyond. Sold as a single unit.
The HTX8HFG sits within the Hertz Marine speaker range and is engineered specifically for tower mounting in marine environments. The common motor compression driver design shares a single high-density flux ferrite magnet assembly between the woofer and tweeter, reducing overall size and weight without sacrificing acoustic output. The FEM-optimised waveguide controls dispersion for a focused, linear SPL response across the full frequency range.
The long-throw 51mm (2") voice coil woofer is tuned for sealed box applications, and the built-in crossover includes a resettable solid-state tweeter protection circuit. A waterproof acoustically transparent screen dust cup protects internal components from water ingress. The cone uses pressed paper with a water-repellent treatment, and the dome is polyamide construction.
Common motor compression driver: A single high-density flux ferrite magnet assembly powers both the woofer and tweeter, improving acoustic performance while reducing the overall size and weight of the speaker unit.
FEM-optimised waveguide: The waveguide is engineered using finite element modelling to deliver a focused and linear SPL response, maintaining full-range sound quality at distances of 100 feet and beyond.
200W RMS, 400W peak power handling: Handles sustained power demands in open-water environments where high output levels are required to overcome wind and engine noise.
98dB SPL sensitivity: High sensitivity rating means more output per watt, reducing the amplifier power required to achieve loud, clear audio on the water.
Long-throw 51mm voice coil woofer: The 51mm (2") voice coil is fine-tuned for sealed box applications, providing extended low-frequency excursion and controlled bass output in a marine tower enclosure.
Sealed built-in crossover with tweeter protection: The onboard crossover is fully sealed against moisture, and the resettable solid-state tweeter protection circuit safeguards the tweeter from overpower damage.
Waterproof acoustically transparent dust cup: The screen dust cup keeps water and debris away from internal components while allowing sound to pass through without acoustic interference.
Water-repellent pressed paper cone: The cone material is treated for water repellency, maintaining performance and structural integrity in wet marine conditions.

Is the HTX8HFG sold as a single speaker or a pair?
The HTX8HFG is sold as a single speaker unit. Two units would need to be purchased for a stereo pair installation.
What amplifier power is recommended for the HTX8HFG?
The HTX8HFG handles 200W RMS continuous and 400W peak at 4 ohm. An amplifier rated within this power range at 4 ohm is recommended for best performance. Contact us for amplifier pairing advice.
Is the HTX8HFG suitable for sealed box tower enclosures?
Yes. The long-throw 51mm voice coil woofer is specifically tuned for sealed box applications, making it well suited to marine tower enclosures.
How does the common motor compression driver differ from a standard coaxial driver?
The common motor design uses a single magnet assembly for both the woofer and tweeter rather than separate motor systems, reducing size and weight while improving acoustic efficiency and output consistency across the frequency range.
What protection does the HTX8HFG have against water damage?
The speaker features a waterproof acoustically transparent screen dust cup, a water-repellent pressed paper cone, and a sealed built-in crossover. The tweeter is further protected by a resettable solid-state protection circuit.
