Hertz was first founded by an Italian consumer auto products manufacturer in 1998, in order to exclusively produce high-quality automobile audio solutions such as speakers, amplifiers, subwoofers, etc.
Hertz has been making innovative and cutting-edge products since then and they offer complete audio solutions for both novices as well as experts.

Their Mille series features the very best Hertz has to offer in terms of sound quality and design. Mile speakers are available as components, coaxials, systems, or subwoofers. Then you have the Hi-Energy series which is designed to provide powerful audio across multiple platforms such as cars, vans, trucks, etc.
The Hi-Energy series too contains component speakers, subs, coaxials, and systems. Then there is the Energy series, designed with a concept of creating efficient, compact, and affordable designs for the everyday customer.
The Energy series is a perfect option for upgrading your OEM sound system, as it is both easy to install as well as highly versatile. Hertz speakers for each of these series come in various power and driver configurations.
There is also the brand new Dieci series which is designed to take a brand new approach towards designing car audio.
It delivers uncompromising sound performance from any angle of listening, thanks to the revolutionary design techniques of Hertz. You can install the Dieci anywhere in your car and enjoy the same amazing sound. You will feel like the sound waves are not coming from where the speaker is located, rather from a different direction.
With all that said, there will be pros and cons to each of these Hertz speakers, your job is to choose a speaker that appears to be the best choice for you according to your needs.
Review Of Hertz Coaxial Speakers
6.5 Inch Picks
Our Pick: Hertz HCX 165
Made from premium materials, this 6.5″ speaker is both great-sounding as well as great in terms of durability.
The water-repellent pressed paper cone on the speaker is light and responsive, yet stiff enough to not resonate along with the other parts.
The speaker system makes up for its mere 200W of RMS power handling by sporting a super sensitive 92dB SPL rating that allows every tiny bit of power pumped into this coaxial, to come out in the form of loud, ear-shattering sound.
But don’t try to get too cocky and throw one of these in your SUV’s. The limited driver size of just 6.5″ doesn’t allow it to perform very well in larger spaces.
On The Budget: Hertz DCX 165.3
If you want a 6.5″ Hertz speaker coupled with a neodymium magnet driving assembly for super cheap, then this is the perfect thing for you.
The sound is obviously lacking, but not in terms of quality as much as it is lacking in terms of quantity. Meaning that the little speaker unit’s tiny 60W RMS power handling really hurts it when it comes to generating deep, loud sounds.
But as long as used in a smaller car you will be just fine as it will function reliably and generate super crisp sound without any annoying distortions.
On top of that, it is too easy to install. Literally just unscrew your default coaxial speaker and wire up this little guy, then screw it in. Ready to go!
Just make sure your car’s amplifier meets the 60W RMS supply rating, or you might want to get one amplifier for yourself.
6×9 Inch Picks
Our Pick: Hertz Audio HCX 690 Hi-Energy
While it is no doubt an extremely affordable Hertz 6″x9″ unit, the part about it that really hits hard is the 260W RMS power rating of each speaker in the 3-way configuration, along with a sensitivity level of 94dB.
Most 3-way coaxials sound much better than a regular 2 way coaxial because there is a whole new speaker dedicated to handling the medium tones.
On this Hertz 6×9″ car speaker, however, with a frequency response of 32 ohms to 23-kilo ohms, there is no way that you can outdo the frequency range with a similarly priced or cheaper coaxial speaker.
To hit any lower frequency you would need dedicated bass machines that simply cost too much for the average casual consumer who just wishes to upgrade his car’s default audio.
Runner-up: Hertz ECX-690.5
Due to the constraints of having a rather limited price tag, this speaker setup will be the perfect choice for anyone seeking rich sound at affordable prices.
It is dirt cheap for a 3-way coaxial system and that too system which includes a super tweeter. Now, including a super tweeter means that the medium to high-frequency behavior is great, but the low to medium frequency range still feels lacking in terms of sound depth and weight.
It is easily overlooked by the unit’s compact size and super high 95dB sensitivity, however. On top of weighing less than 10 pounds, it has an RMS power rating of 300W which is great for such a well-priced unit.
On The Budget: Hertz DCX 690.3 Dieci Series
While this particular budget 6×9″ speaker does come with a 3-way speaker setup in a coaxial configuration, at this price we were not expecting any chest thumping sound output.
With a power rating(RMS) of just 90W, this speaker setup disappoints in terms of raw volume and bass output, but scores well for the deliverance of crisp and non-distorted audio, thanks to those powerful driver magnets, and that ultra-light paper dome tweeter which responded well to an electric signal shot into it.
Review Of Hertz Component Speakers
Component 6.5 Inch Picks
Our Pick: Hertz HSK 165
If you are purchasing this to experience the mind-numbing thumps of a jacked-out subwoofer configuration then you will be thoroughly disappointed because the ultra-low frequency range performance is sort of okay…however, the tweeter on this set of Hertz component speakers is definitely unlike anything else you will ever hear at this price range.
The high tones and shrill notes are crystal clear and are highly audible even in a larger vehicle running at high speeds on a highway with the wind blowing all over the cabin. That is because of the 125W RMS power rating on its speakers, coupled with an amazing 25mm neodymium tweeter and a 165mm subwoofer.
Runner-Up: Hertz ESK 165.5
With RMS of 300W, this component speaker setup will have you wondering as to whether you should buy it or not despite its amazing build quality.
If you buy it, you will need to attach a good amplifier to it in order to fully utilize the potential of that subwoofer, because it has a really low power rating and you need to pump some serious wattage into that thing to get it going… however once it begins pumping out bass at full volume there are few car audio systems that can directly compete with it at this price range, so you are going to be one happy customer knowing that your extra investments actually paid off.
The crossovers switch from low pass to high pass at about 3 KHz and 6-12dB, and a unique V-cone design allows for crisper mid to high-frequency performance along with better off-axis performance that allows you to hear great sound no matter how you are positioned with respect to the speakers themselves.
On The Budget: Hertz DSK 165.3
Just 80W of RMS power is all your little new speaker set gets to play with, so don’t expect to hear loud volumes or high sound output.
However, a system does not need to be loud to establish itself as a good sounding speaker system if it can accomplish the task at half the volume.
The Dieci Series component system proves that principle with crisp, non-distorted audio for the music of any genre and can accurately reproduce the highest as well as lowest of frequencies without breaking a sweat, a feat that most cheap car audio systems don’t even try to achieve.
For such a low price you are getting a 2- way subwoofer and tweeter system with a 320W RMS power rating per set, and 160W on each side. Frequency response is incredibly tight at 50Hz to 23 kHz, meaning it can easily handle the extreme lows as well as the shrill and high pitched uppers.
Component 5.25 Inch Pick
Our Pick: Hertz ESK 130.5
This is a two-way component speaker system with a total RMS wattage of 450W, meaning that each side gets an effective 225W RMS wattage, and each speaker gets 75W only, meaning no load thump-thump for all you bass heads, but that is something we have come to expect from smaller and cheaper component speaker setups.
But this one delivers big in all other areas, especially portability and compactness. The bass driver may be small at just 5.25″ but it still delivers great sounding bass in smaller vehicles such as hatchbacks and subcompacts.
The speakers operate between 70Hz to 23KHz, meaning the absolute bottom frequency is slightly higher on this one, and deep low rumbles will not sound as good as they do on a larger subwoofer in a bigger audio system.
But for a system this small and affordable, the Hertz ESK 130.5 gets the job done just fine.
