The first generation of Diamond Monitor 18 set the standard in its category, making designing its successor a unique challenge. In the latest version, we have improved these speakers by equipping them with upgraded drivers, enclosures, and crossovers. Additionally, we have subtly updated their design to give them an even more refined appearance.

The woofer is a transducer heavily modified by our engineers and made by the Norwegian company Seas. Its powerful magnetic circuit, reinforced with an additional magnet, works in conjunction with a lightweight aluminum-copper coil, resulting not only in greater dynamics but also better precision in reproducing bass and mid-bass. The injection molded aluminum chassis with an openwork design allows for accurate sound reproduction. The Diamond Monitor 18 mkII also features a bass-reflex port with an increased cross-section, while maintaining similar enclosure tuning. As a result, the lowest frequencies are reproduced more efficiently, eliminating audible turbulence.

Through these improvements, the quality of midrange tones has also been enhanced. The aluminum-copper coil wire is an ideal solution not only due to better optimization of the masses of individual vibrating system elements but also due to reduced effects of so-called skin effect currents flowing in the speaker coil. The use of a 1-inch voice coil ensures excellent microdynamics in the midrange. Additionally, instead of a traditional dust cap, the woofer has been equipped with a phase plug, eliminating resonances associated with the volume of air under the cap. The coated lightweight cellulose membrane allows for a tonally balanced warm sound over a wide frequency range. The gentle decrease in level at the upper limit of the mid-bass speaker range also allows for smooth transition to the range reproduced by the tweeter.

In the high-frequency range, the iconic Scan-speak tweeter operates in a new version, characterized by exceptional microdynamics and detail due to the use of a stronger neodymium magnet, reduction of the voice coil mass, and elimination of ferrofluid. The high-frequency speaker easily integrates with the mid-bass through a new dual resonance chamber design, which has allowed further reduction of the tweeter's fundamental resonance. These changes allow for a clean reproduction of the full instrumental soundscape.

The advanced crossover network in the Diamond Monitor 18 MKII has been constructed using only linear elements such as air coils and polypropylene capacitors, contributing to improved sound clarity.

In the latest monitors, we have opted for a 4-ohm impedance. This means that the second-generation eighteens are twice as loud and fully utilize the power offered by the amplifier. As a result, dynamics significantly increase, and the speakers can be dedicated to slightly larger rooms.

The Diamond Monitor 18 mkII features a greater front tilt, improving the transducers' performance in the time domain. The overall shape looks much better. The black cellular rubber on the tweeter gives it an exclusive character and increased aging resistance. Meanwhile, the vertical veneer grain adds sleekness to the whole.

Vibration of the enclosure walls is significantly reduced thanks to extensive internal ribbing. Undesirable standing waves inside the enclosure are dampened by sheep wool and a new sound-absorbing material, specially selected during tests in our anechoic chamber using a laser vibrometer. Hence, the monitor sound is free from tonal impurities.

The Diamond Monitor 18 mkII is a speaker characterized by refined low-end dynamics, delivering controlled and subtle bass. Along with excellent balance of mid and high tones, it provides exceptional naturalness in both instrument and vocal reproduction. The acoustic space it creates allows for precise localization of individual instruments, resulting in clear and distinct sound for each note.

The columns are dedicated to the rooms of 12 - 25 m2.

The sets are provided with the branded stands that create an attractive proposition for people who would like to use the full potential of the columns in their spatial capabilities.
