Information About This Item

Taking Premium Sound Off-Road

High quality audio is no longer just for your car or home, with Hertz a brand well known the world over for producing some of the best audio gear on the market stepping into a new market and developing a range of speakers, subs and amplifiers for outdoor Powersports applications such as offroad and all-terrain vehicles.

The Hertz HMX8S-LD 8" Powersport Coaxial Speakers are a high performance 2-way outdoor speaker designed to bring a new level of quality audio to open-top and leisure vehicles. Optimized to perform in infinite baffle, with solid bass and an outstanding output, they feature HMX tweeters with an acoustic lens which help to deliver the best off-axis dispersion possible, maximising SPL.


Engineered and tested to withstand harsh outdoor enviroments, the HMX8S-LD are able to handle exposure to UV, salt-fog, vibrations, water spray, thermal shock and dust whilst attractive, stainless steel tweeter mesh grilles provides perfect high-frequency transfer and a rock-solid protection.  

In addition to crystal clear sound these speakers are able to produce, Hertz have also added an RGB LED lighting circuit, integrated just below the tweeter, protected by a Polypropylene transparent cover acting as light diffusion. The result is a cool, mood lighting effect that is certain to add a touch of class to your vehicle.


Want to spice things up even more? Add the HMRGB1BK wireless remote control (sold seperately) for complete control of the multicolor LED lighting that can be changed to fit your mood or craft and even set to react to the beat of the music.
