In the Swans Antarctic release, the H2 is the first product of the Swans H series. After eight months of development, the Swans H4 debuted in Swans H series. The highlight of the cabinet design lies in its exquisite craftsmanship and the cutting edge technology of the new electro-acoustic amplifier circuit.
H4 is a luxury speaker made of natural ebony veneer and polished with the piano technique surface only applied to flagship products. The product is entirely hand finished and hand painted. When the H4 is placed under a soft light, the shine of its quiet and luxurious texture is well refracted and revealed.
The cabinet front of the Swans H4 is covered with a leather panel and piano lacquer. The embossed soft leather has a rich and smooth texture.
The H4 is a 2-way electronic crossover design installed with the active crossover / frequency tuning circuit. Driven by Swansā¢ latest 19mm hard metal dome tweeter, TN19-S, its diaphragm is made in durable components yet its weight is extremely light. Its separation of frequency is so high that is beyond our hearing range. In order for the H4 monitor speakers to possess top performance, the pairings of the treble drivers are incredibly precise to ensure the perfect frequency response crossovers.
The H4 bass is a new 4-inch mid-bass woofer G4N in a bowl shape. The longer stroke design in the H4 increases circulation for air. The small cabinet design possesses the same dynamic and dipping that can be found in large size speakers. The low frequency can extend smoothly to 60Hz, with a system frequency response of 60Hz-20kHz Ā± 3dB (free range), optimal for professional monitoring.
The H4 has a single amplifier design to ensure user friendliness. Each H4 speakerā¢s front lower-right corner is installed with a power switch for controlling and adjusting the power and volume. The back panel is equipped with settings for the adjustment for Bass: 1dB (10KHz), Mid-range: 0/-2/-4dB (500Hz), Treble 0 / Ā± 1dB (10KHz). These rich tuning options allow users to select based on their preferences and their environment when adjusting the frequency responses. The high frequency adjustable 60Hz/66Hz / 72Hz / accommodates users by adding a separate subwoofer to configure the X.1 system.
Although H4 is in the area of ā¹ā¹home monitoring and home entertainment applications, it is very well equipped driving the power when facing the challenges in variety of applications. Below is the power amplifier assembly Figure of H4. The power amplifier back has the thickness of 5 mm aluminum for extra support as well as to diffuse heat to cool the system. Since H4 is a small monitoring system with limit space for circuit arrangements, the engineers are focusing to the efficiency of circuit designs and internal structures.
From the back of the H4 amplifier circuit board, we can see its internal structure being divided into three parts: the pre- signal adjustment control, the rear enlarged portion, and the built-in cooling radiator. The built-in high density radiator fin rapidly transfers heat into the air and through the port tube, pushing the air out from the box. Both the front and the back of the circuit boards are made of high-end glass fiber and boast the extensive use of SMD components, effectively reducing the circuit size and increasing the consistency of the circuit.
