This enables these speaker units to be integrated into a variety of vehicle models. It is important to check the available installation space in the vehicle before making a decision to ensure that the speakers fit ideally.
The installation of the Diamond 165/2 MKII speaker set begins with selecting a suitable installation location in the vehicle, usually the doors or the rear shelf. Once the installation locations are defined, holes should be drilled for the installation diameter of the tweeters (45 mm) and woofers (145 mm). The installation depth of 19 mm for the tweeters and 73 mm for the woofers must be observed to avoid damaging any body components. The speakers are then connected and positioned to achieve optimal sound in the vehicle interior.
The maximum impedance of the Diamond 165/2 MKII is 24.9119 Ω, and this value is particularly important for understanding the load capacity as well as the electrical stability of the speaker. Impedance measures electrical resistance and affects how the speaker harmonizes with different amplifiers. At 4 Ω nominal impedance, the speaker operates optimally with a wide range of amplifiers, while the maximum value ensures that even in demanding scenarios, no overload occurs. This is a key aspect for the longevity and audio performance of the speaker.

Frequency curve analysis: From 39 Hz to 20,000 Hz

The frequency response of the Diamond 165/2 MKII extends from 39 Hz to 20,000 Hz, ensuring excellent coverage of the acoustic bandwidth. Low frequencies at 39 Hz provide a solid bass foundation, ideal for music with plenty of depth. High frequencies up to 20,000 Hz accurately capture the details of delicate high-hats and violin-like instruments. If the frequency range is narrower, as is the case with few speakers in the car hi-fi sector, clarity suffers at maximum volumes. A broad frequency range minimizes distortion and audibly improves detail.

Efficient sound: efficiency of 90 dB

With an efficiency of 90 dB, the RS Audio Diamond set produces powerful sound with a lower electrical input power. By comparison, speakers with an efficiency of 85 dB require twice as much power for the same sound pressure level. This makes the speaker more efficient and ensures energy-efficient playback, which also benefits your car battery. If the efficiency is lower, you may need a more powerful amplifier to achieve the same sound level, which could incur additional costs.

Powerful 90/180 watts: RMS and maximum load

The Diamond 165/2 MKII offers 90 watts RMS, providing excellent audio quality without overloading in normal use. The maximum power rating of 180 watts gives you the confidence that the system won't collapse under the strain, even at high volumes. Higher power ratings would allow the speaker to offer greater flexibility, even during intense bass passages or louder music sessions. Nevertheless, it offers sufficient headroom for most applications.

Construction: Silk dome and carbon cone for perfect sound signature

When it comes to materials, RS Audio relies on silk domes for the tweeters and carbon fiber for the woofers. Silk domes are known for their smooth sound reproduction and precise high-frequency reproduction. They reduce the aggressive peaks often found in metal domes. The carbon fiber cone provides rigidity and minimal weight, lending a crisp low- and mid-frequency response. Choosing other materials could compromise stability at high volumes.

Precisely tuned crossover: 6/6 dB

The Diamond 165/2 MKII's crossover is specified at 6/6 dB, which ensures optimal sound separation. This smooth crossover characteristic offers minimal phase shift, which directly benefits the clarity of each track played. A higher dB specification might have harshened the signal separation, resulting in sharper transitions. The chosen 6/6 dB layout reflects a well-thought-out balance between clarity and volume.

4 Ω impedance: adaptability and efficiency

With its 4-ohm impedance, the speaker demonstrates excellent adaptability to various amplifier types without compromising on quality. A lower impedance could result in increased load, while a higher impedance would result in less efficiency at a given power output. In this context, 4 ohms represents the ideal balance between performance and flexibility, ideal for both classic and modern amplifier systems.

Stable construction: installation diameter and outer diameter

The woofer of the Diamond 165/2 MKII has a 145 mm mounting diameter and an outer diameter of 166 mm, while the tweeter has a 45 mm mounting diameter and a 56 mm outer diameter. These dimensions optimize installation in vehicle interiors and are compatible with standard mounting bays. Deviating from these dimensions would risk the speakers not fitting into standard mounting brackets.

Detailed Thiele-Small parameters: Insight for the connoisseur

The understanding of technical details is demonstrated by Thiele-Small parameters such as a resonance frequency of 40.0874 Hz and a Qts of 0.6474. These values ​​reveal the resonance behavior and electromechanics of the loudspeaker. A lower resonance frequency indicates more robust woofers with more bass headroom. A Qts close to 0.5 demonstrates good balance, ideal for sealed and bass-reflex enclosures. A high RMS of 0.9534 ΩM and a BL of 4.5707 Tm provide power and magnetic flux, enabling precise movements.
