High Efficiency: Maximizing Power, Reducing Strain, and Simplifying Cu

High Efficiency: Maximizing Power, Reducing Strain, and Simplifying Custom Installations

DC GOLD speakers are classified as highly efficient audio components, a critical feature for custom installers, builders, and anyone operating off a limited power source.

The Power-Saving Advantage: High Sensitivity

Speaker efficiency is measured in sensitivity, typically boasting 90 dB to 95 dB per watt.

The Physics: Because a speaker that is 3 dB more efficient requires only half the power to achieve the same volume, DC GOLD speakers require significantly less amplifier wattage to achieve the required volume compared to lower-efficiency speakers.

The Result: This allows builders to use smaller, cooler amplifiers, ensuring greater amp reliability. More importantly, it results in lower current draw from the 12-volt battery system, preserving battery life and avoiding costly upgrades to alternators or power infrastructure.

System Flexibility: The Critical Impedance Advantage

The availability of multiple impedance options 2 Ohm, 4 Ohm, 8 Ohm and custom impedance’s available with minimum orders is essential for complex audio design.

• Maximizing Volume (The 2 Ohm Option): For high-impact setups, if amplifier allows, the 2 Ohm load allows the amplifier to deliver its maximum power (often double the 4 Ohm), providing the loudest volume possible from a single channel.
• Simplifying Large Zones (The 8 Ohm): For multi-zone installations (yachts, resorts) and custom installers that must wire many speakers safely. By using 8 Ohm DC GOLD speakers, installers can safely wire up to four units in parallel, resulting in a safe and efficient 2 Ohm load. This drastically simplifies the amp rack and saves on hardware costs. The 8 Ohm is also the standard replacement for the Lexus Mark Levinson Audio®, our N69 with the 8 Ohm coil is one of the few and the absolute best replacement speaker on the market.
• The 4Ohm, Gold Standard: of most 12 volt mobile systems, whether boats, motorcycles, jet-skis and so on is the 4 Ohm coil. Most amplifiers are rated for 4 Ohm, this standard has been around decades and will be around for decades to come.
