DD Audio VO-B4a: Discover the extended frequency response from 2k to 20k Hz

The DD Audio VO-B4a horn tweeter offers an impressive frequency bandwidth of 2kHz to 20kHz. This generous frequency coverage means you'll hear even the finest sonic details in your audio system. The extension at the top end allows the VO-B4a to deliver crystal-clear highs and reproduce brilliant timbres. A wider frequency response like this ensures the tweeter's versatility, reproducing a wide range of music genres with the same precision. A lower frequency response would increase the tweeter's bass content, but is usually less desirable, while a higher frequency average increases the clarity and definition of highs.

Buy: Extremely high efficiency with an efficiency of 108 dBSPL

With an impressively high efficiency of 108 dBSPL, the VO-B4a delivers exceptional volume with minimal energy consumption. This efficiency is especially beneficial if your audio system is powered by a limited power source. High efficiency like this ensures less power loss between the source and the speaker, giving you more sound per watt. A lower value might require more amplification to achieve the same volume. At Masori.de, you can buy this efficiency champion at a great price, backed by our lowest price guarantee.

Flexible mounting options thanks to the 110-degree horn body

The VO-B4a features a 110-degree horn body, which allows for sound dispersion over a wider area. This results in a better listening experience, as the sound is evenly distributed to different listening positions in the vehicle. Unlike narrower angles that focus the sound in one area, the wider angle of this tweeter provides more comprehensive coverage and reduces hot spots in the sound field. The aluminum body also ensures structural integrity. The 110-degree angle offers mounting flexibility, allowing the tweeter to be used either to enhance the sound ambience or for focused audio applications.

Buy online: Replaceable titanium membrane for durability and precision

The VO-B4a's replaceable titanium diaphragm offers the perfect combination of lightness and robustness. Titanium is known for its durability and ability to deliver ultimate acoustic precision. This replaceability increases the tweeter's longevity by allowing you to easily replace damaged or worn diaphragms. Materials like plastic would potentially wear out faster and could compromise sound quality. Titanium, on the other hand, offers excellent resonance, minimizing distortion and maximizing high-frequency clarity.

Efficient power handling: 50 watts RMS and 150 watts peak power

The VO-B4a can handle 50 watts RMS power and up to 150 watts peak power. These power ratios ensure both long-term, consistent performance and the ability to handle short-term power peaks without overloading the tweeter. A higher RMS power rating would be useful for systems that play at consistently high volumes, but this value offers enough flexibility to maintain performance in a wide variety of applications. At peak power, the tweeter can handle short, dynamic audio peaks without clipping, supporting distortion-free sound reproduction.

Buy online: 4 ohm impedance for excellent compatibility

With an impedance of 4 ohms, the VO-B4a is largely compatible with most car hi-fi amplifiers on the market. This ohm value ensures an optimal balance between resistance and efficiency, which is important for maximizing both sound quality and volume without unnecessary power loss. A higher impedance could mean requiring more voltage, which would be suboptimal in a standard setup. The 4 ohm impedance ensures you can fully utilize the tweeter, providing excellent sound detail and power. Masori also offers on-site installation in Frankfurt (Oder) .

Anodized aluminum heatsink for consistent performance

The VO-B4a's anodized aluminum heatsink ensures efficient heat dissipation, stabilizing the tweeter's performance. Aluminum is an excellent heat conductor, and anodizing improves corrosion protection and extends the heatsink's lifespan. An effective cooling process ensures the tweeter can continuously operate at its optimal operating temperature, which in turn reduces signal distortion caused by overheating. Inadequate cooling could lead to thermal problems and a degradation in audio quality, but the DD Audio heatsink is specifically designed to prevent such problems.

Push-terminal speaker connectors for reliable connection

The VO-B4a's push-in terminals offer added security and ease of installation. This type of connection is known for its high reliability, as the connections are secure and won't break easily, even under strong vibrations. A screwed terminal could become loose if not properly secured, leading to intermittent signal interruptions. Push-in terminals also ensure quick and effortless wiring, simplifying the installation process and ensuring consistently high-quality sound performance.

Frequency protection circuit with 12dB high-pass filter for protection and quality

The VO-B4a features a 12dB high-pass frequency protection circuit that effectively reduces overloads and protects sound quality. This built-in circuit filters out lower frequencies that could damage the tweeter or impair its performance. The effective function of the 12dB octave provides a clearer and more focused treble range by ensuring protection against unwanted frequencies. A weaker high-pass filter might not filter sufficiently and increase the risk of damage. DD Audio's innovation ensures you experience pristine sound clarity and stable performance at all times.
