Frequently Asked Questions about HMS 12 B2-LD-W

What features distinguish the Hertz HMS 12 B2-LD-W Subwoofer?

The Hertz HMS 12 B2-LD-W is a 12-inch marine subwoofer, ideal for free-air applications. With a continuous power handling of 500 watts RMS and a peak power handling of 1000 watts, it delivers impressive performance. The 2-ohm single voice coil ensures optimal efficiency. The cone is made of UV-resistant polypropylene, making it durable for outdoor use. The subwoofer has a maximum linear excursion capability of 19 mm, providing deep and powerful bass. Its magnet is made of high-density ferrite. With a sound pressure level of 89.5 dB and a resonance frequency of 30 Hz, it offers impressive bass reproduction.

How does the 2-ohm impedance affect the sound quality of the HMS 12 B2-LD-W?

The 2-ohm impedance of the HMS 12 B2-LD-W means that the subwoofer offers less resistance to the amplifier, leading to more efficient power utilization. This can result in higher volumes and a more dynamic bass response. However, the lower impedance may require you to ensure that your amplifier can also handle 2-ohm loads to avoid overheating or damage. The low resistance is often beneficial in high-power marine systems, as it allows for maximum bass performance in open environments like a boat without needing a closed enclosure.

Why is the HMS 12 B2-LD-W Subwoofer suitable for free-air applications?

Free-air subwoofers like the HMS 12 B2-LD-W are designed to deliver optimal performance without closed enclosures. Thanks to technological optimization, particularly the Mms of 114 g and the Vas of 95.4 l, the subwoofer produces powerful bass reproduction even in open environments. These features relieve the main speakers of heavy low-frequency tasks, maximizing the overall performance of the sound system. The BL product of 8 T*m and the robust electromagnetic specifications support clear and distortion-free bass production in your marine installation.

What is the sound pressure level and what significance does it have for the HMS 12 B2-LD-W?

The sound pressure level (SPL) of the HMS 12 B2-LD-W is 89.5 dB. The SPL value indicates how efficiently a speaker converts sound in relation to electrical input power into acoustic output. A higher SPL value means that a higher volume level is achieved with the same input power. Especially if you enjoy listening to music loudly, the SPL of 89.5 dB allows impressive volume outdoors on your boat without excessive power amplification. This is particularly advantageous in open marine environments where you want to compete against background noise.

What are the dimensions of the Hertz HMS 12 B2-LD-W and how do they affect installation?

The Hertz HMS 12 B2-LD-W Subwoofer has a diameter of 300 mm and a cabinet depth of 191 mm. The external dimensions are 'A' 342.9 mm and 'B' 279.4 mm, which describe the size at the top of the Subwoofer. The installation depth of 191 mm is crucial for placement, as it helps ensure that there is enough installation space in your marine environment. The magnet measures 156 x 80 x 40 mm. Note these dimensions to ensure a hassle-free installation and to make sure the Subwoofer can be properly mounted without space issues.

What are the electrical specifications of the HMS 12 B2-LD-W and how do they affect performance?

The HMS 12 B2-LD-W offers specific electro-acoustic specifications such as a coil size of 65.5 mm, a resonance frequency (Fs) of 30 Hz, and a Re of 1.8 Ohm. An Le of 0.41 mH, combined with a Qts of 1, a Qms of 11.1, and a Qes of 1.1, defines the performance in operation. These measurements are crucial for converting electrical signals into acoustic energy and define the overall quality of the bass sound. When these parameters are optimally matched, it allows the Subwoofer to produce powerful bass and precisely controlled acoustic output.

What materials were used in the cone of the Subwoofer and why?

The cone of the HMS 12 B2-LD-W is made of polypropylene with UV inhibitors. Polypropylene is known for its strength, flexibility, and lightweight construction, making the cone less susceptible to damage at high volumes. The integration of UV inhibitors protects the Subwoofer from sun damage and extends its lifespan, especially in marine applications where UV exposure is common. This combination of materials ensures long-term durability and consistent acoustic performance even under extreme weather conditions.

How do the LED features enhance the use of the Hertz HMS 12 B2-LD-W?

The Hertz HMS 12 B2-LD-W Subwoofer is equipped with an adjustable LED RGB controller that can be operated via a remote control. The LED lighting can be adjusted to match moods or environments, significantly enhancing the visual experience when using the subwoofer on your boat. The RGB controller allows you to select different colors and light patterns, which elevate the marine audio experience. Especially when you take night boat trips, the lighting provides an aesthetic upgrade and visibility of the subwoofer in your marine audio system.

How do I install the HMS 12 B2-LD-W on a boat and what should I consider?

When installing the HMS 12 B2-LD-W, ensure that there is enough space for the subwoofer with a diameter of 300 mm and a mounting depth of 191 mm. A stable mounting surface is essential to minimize vibration transfer that could affect sound quality. Consider the positioning to ensure optimal bass reproduction and to adjust the frequency response. It is important to properly route the cables and set the amplifier correctly to the impedance of 2 ohms to extract the full power from the subwoofer while avoiding damage.

What accessories can be used to expand the HMS 12 B2-LD-W?

The Hertz HMS 12 B2-LD-W Subwoofer can be expanded with the HM RGB 1 BK accessory, which can extend the functionality of the LED lighting. This accessory includes an RGB controller specifically designed for the HMX LD option models and comes with a remote control. This allows you to conveniently adjust the LED colors and modes to change the visual atmosphere. This accessory enhances the visual experience and ensures that the subwoofer stands out not only in sound but also in appearance, which is particularly beneficial during night boat trips.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.
