Hertz HMS 10 S2-LD-G.1 boat subwoofer

Hertz HMS 10 S2-LD-G.1

Hertz HMS 10 S2-LD-G.1 is a powerful 10" marine subwoofer in a grey sporty finish, designed for boats, vessels and other demanding outdoor applications. It delivers deep, tight and dynamic bass and represents the ideal solution where a pronounced bass foundation is required with more compact dimensions than 12" subwoofers.

The 2 Ω impedance allows efficient use of power from a compatible marine amplifier and achieves high acoustic pressure even in open spaces. Integrated LED lighting gives the subwoofer an attractive look and allows you to match its design with deck lighting or other illuminated Hertz Marine components.

The construction is adapted for long-term operation in harsh marine environments and accounts for exposure to water, humidity, UV radiation and salty conditions. Hertz HMS 10 S2-LD-G.1 is suitable for high-power marine audio systems where pronounced bass, compact installation and high durability are important.

About the brand

Most well-known European brand in the car hi‑fi segment? Hertz audio! It's a brand that was founded in 1998 in Italy. Hertz belongs to Elettromedia, which owns Hertz, Audison and Connection. How did the name Hertz come about? Hertz — the unit of frequency, the number of cycles per second (Hz). Everything in Hertz car audio reflects that they are a brand passionate about music, caring about everything Hertz produces. Over the years the company has built an excellent team of talented and dedicated engineers committed to designing products at the highest level. Every new project and product originates primarily from the needs of the brand's fans and is developed to connect them directly with the emotional power of music. The Hertz brand philosophy is a unique combination of premium sound, living tradition, clever innovation and high quality, combined across a complete product range for maximum customer satisfaction. Hertz offers a complete line of speakers, amplifiers and subwoofers that lets you experience the thrill of high‑quality sound in any situation. Deep knowledge of in‑car acoustics, design requirements and manufacturing processes keeps Hertz products at a high level. To achieve Hertz's high quality standards, the company is not satisfied with testing samples from each batch: it uses the most advanced testing tools to analyze every component through a computerized inspection process under the supervision of highly qualified personnel. This results in a vanishingly small percentage of returns and high quality across all Hertz products.

Subwoofer diameterThe diameter of the subwoofer is indicated on the screw holes. The overall outer diameter of the subwoofer is usually 1-2 cm wider, depending on the size category of the subwoofer. For a 30 cm subwoofer, the outer diameter incl. protective rubber 31.8 cm and in the 25 cm subwoofer it is 26.5 cm incl. protective rubbers.	250 mm (10\")
RMS powerThe RMS power of the subwoofer is the constant power of continuous use of the subwoofer. If the power is exceeded for a longer period of time, irreversible damage may occur, or to burn out the voice coil of the subwoofer.	250 W
Max. (maximum performancePeak performance , which the subwoofer can play momentarily (approx. 0.5 s), for example when hitting drums in a song. If the maximum power is exceeded, damage can quickly occur, or to burn out the voice coil of the subwoofer.	500 W
ImpedanceImpedance - measurement of electrical resistance. When buying a subwoofer, it is very important that everyone make sure that the impedance matches the amplifier that you are connecting to it. For subwoofers with a double voice coil, we recommend following the information in the advice center! Example: A 2 Ohm subwoofer cannot be connected to an amplifier that is only stable up to 4 Ohms. A 4 Ohm subwoofer can easily be used on an amplifier that is stable up to 2 Ohms. Connecting a 4 Ohm subwoofer to an amplifier that is stable up to 4 Ohms also without problems. The most common subwoofer impedance is 4 Ohm.	2 Ω
Sensitivity (SPL 2.83V/1m)Subwoofer sensitivity or efficiency. The sensitivity of the subwoofer is given in decibels (dB) and, in simple terms, means that the higher the value, the lower the demands on the power of the amplifier. This is a de facto rating of how a subwoofer converts watts to sound. Sensitivity ratings are in noise level measured at 1 meter from the subwoofer using 1 W (watt of power) or using 2.83 volts at the source at 1 meter. A higher decibel level means the subwoofer is louder with less power. For every 3 dB increase in sensitivity, the subwoofer requires half the power to reproduce the same volume. For example, if an 88 dB subwoofer needs 300 Watts to produce a certain volume, then a subwoofer with 91 dB sensitivity needs only 150 Watts to reach the same efficiency.	88 dB
Fs - resonant frequencyFs - is the lower resonant frequency. This parameter is the de facto free air resonant frequency of the subwoofer. Simply put, it is the point at which the weight of the subwoofer's moving parts equals the force of the subwoofer's suspension while it is in motion. If you've ever seen a piece of string start to hum uncontrollably in the wind, you've seen the effect of reaching a resonant frequency. The weight of the moving parts and the stiffness of the suspension (surround and spider) are key elements that affect the resonant frequency. As a general rule, a lower Fs indicates a subwoofer that would be better at reproducing low frequencies than a subwoofer with a higher Fs. However, this is not always the case, as other important parameters of the subwoofer also enter the resulting sound.	41 Hz
Subwoofer voice coil diameterThe larger the diameter of the voice coil, the more load capacity the subwoofer has, in layman's terms.	50 mm
Subwoofer diaphragm materialThe specific material from which the subwoofer membrane is made.	Polypropylene with UV inhibitors
Xmax + -Xmax - the maximum deflection of the subwoofer diaphragm in one direction – it is not a sum, or an abbreviation for the maximum linear deflection. The subwoofer output becomes non-linear as the voice coil begins to leave the magnetic gap.	12.3
Subwoofer mounting depthThe mounting depth of the subwoofer is measured from the bottom edge of the magnet to the bottom edge of the subwoofer's metal or cast basket.	116 mm
Other	Resistant to corrosion, UV radiation, salt spray and jetting water (IP65)
MassSubwoofer weight in kilograms. The weight is usually given net, i.e. without packaging.	5.1 kg
