Monkey Banana TURBO 4 A monitor


Interesting German Monitor with vibrant moods...

(1) LED logo lens: Made from high quality RoHS compliant optical material, it focuses the LED light to clearly project the pride of our brand – yet subtly understating the craftsmanship behind it. This refined approach reflects the quality of the product from the first time you see it.

(2) Enclosure: Made from custom-shaped MDF material, the cabinet is not only stylish in appearance, but also employs serious Engineering to achieve the best acoustic performance. The Bass-reflex acoustic design combines maximum efficiency and optimal bass extension. The MDF material ensures proper damping of vibrations from the drivers that can create audible distortion in the enclosure. All this is done behind a sophisticated industrial design utilizing modern fashion elements. In order to achieve this perfect combination of sound quality and appearance, the Turbo series enclosures were designed as a non-regular hexagon. After careful calculation and experiment, we found that the non-regular hexagonal structure is most effective in minimizing standing waves inside the enclosure. (Standing waves can create audible distortion which can compromise the overall sound quality of the speaker.) We chose high-density RoHS compliant fiber board (MDF) for the enclosure to not only damp out unwanted resonances, but to ensure a solid and inert structure to mount our drivers to.

(3) Screws: All screws are RoHS complaint and zinc plated. They are created using environment-friendly processing, and forged with ultra-high strength steel. Turbo series engineers have paid careful attention to every detail of the design (right down to the screws) in order to deliver products that reflect quality in every way.

(4) Tweeter: Using high quality pure silk from Europe, the patented dome shape perfectly articulates the high frequencies. It is designed to have a low resonance (for a low crossover point) but also high power handling. The rare-earth neodymium magnet is not only extremely efficient, but also is inherently magnetically-shielded. As with all Monkey Banana products, it is made from only the best environment-friendly materials. With high-temperature voice coil, this tweeter is as powerful as it is graceful in its sound reproduction.

(5) Woofer: Using patented technology from the Aviation industry, the PP carbon fiber / ceramic composite cone strikes a perfect balance between strength and weight. This lightweight yet strong cone ensures an extremely fast transient response from bass notes all the way through to the midrange. The cone geometry also ensures extreme power and heat resistance, whether playing loud rock or subtle classical music. The magnetic structure is a shielded design and of course made from all environment-friendly materials.

(7) Made using latest “green” plastic injection molding techniques, the port has been designed to maximize the acoustic output of the woofer. Using the latest in aerodynamic technology, the port effectively tunes the cabinet to the optimum frequency, while minimizing any air turbulence noise from the powerful movement of the woofer. As the woofer moves, the port also acts to move large volumes of air in and out, and ventilate the internal heat generated by the amplifier. Using complex computer simulation, we can perfectly match the woofer to the enclosure design – and create an optimal sound reproduction experience.

(8) Amplifier: The custom-made amplifier design uses only professional grade multi-layer PC boards (compared with the single sided PC boards used in other speakers). This ensures that the circuitry and components have better reliability and better performance – which in the end means higher fidelity sound. Only audiophile grade components and high-tech SMT manufacturing are using in the making of our products. Our electronic circuitry also must meet the highest European Pb free standard and RoHS compliance. The custom-made components are carefully selected using the most advanced and demanding industrial standards. The Class-AB power amplifier design is mature and very stable. Its energy-efficient performance ensures maximum efficiency while providing extremely accurate music reproduction.

(9) Amplifier panel: Made from tempered steel, the extra thick amplifier panel provides excellent heat dissipation, while damping out any vibrations made by the woofer. The panel also features all flush mounting screws to ensure an adequate air seal to the cabinet. Surface is painted matt black using only environment friendly paint.

(12) IEC AC input Socket: Global safety lab tested and approved high quality socket. Incorporating an in-line breaker fuse in the assembly assures that no harm is done to the circuit from any unwanted power surges. Within the housing, there is also a conveniently located spare fuse – which can come in handy if you’re having a party…. The AC socket was designed with power purifier design concept, greatly ensured the stability and purity of the power supply.

(13) Toroid transformer: The audiophile grade coil provides clean power to the amplifier. Designed to minimize vibration noise, magnetic flux leakage and electromagnetic interference, it is also solidly built – eliminating any potential noise. This toroid guarantees the amplifier will be free from interference while delivering consistently, long-lasting high power.

(14) Steel mounting washer: This mounts the toroidal transformer firmly to the amplifier panel, while minimizing the transformer resonance.

(15) Amplifier heatsink: Constructed from the finest quality aluminum, the heatsink acts to dissipate the heat generated from the amplifier IC chips. The heatsink not only cools the amplifier itself, but also helps to remove heat generated by the drivers as well. Utilizing thermodynamic design, the heatsink is mounted vertically on the amplifier panel – which is placed right behind the woofer. Orienting the slots vertically and with sufficient space between them, allows optimum heat removal. The woofer’s pistonic movement also helps to dissipate the heat faster, as the heat is then ventilated from the port to the outside of the speaker box.
