Callas PM-103 Silver 4inch Woofer 2Way Active Desktop PC Speaker 100W

More details

Active Speaker CALLAS PM103, it is made of the craftsmanship of sound. With sound which is confidently advancing to “Reality”, the dream of audio, it contains a performance space and sound altogether. It visualizes the sound space with High Fidelity on your desk. Its silhouette of round type is not a choice just for design. Aluminum body, harmonized orange stripe connected to curved type baffle, stand with angle of beam spread which is beneficial, they are provided as basic option. Stand is manufactured from Cold Rolled Steel of 3mm thickness which was press processed, it has excellent durability and offset the vibration generated from body effectively during music play to disperse them to the surface of floor. Through angle of beam spread of 10˚, listeners can concentrate to the sound in general desktop service environment, which helps to form accurate sound image. If you stick attached silicone anti-vibration pad on the surface, you can operate stably even in slippery environment such as glass surface. To control angle more delicately by bending and unfolding stand in particular cases, you can use to fit the situation.Its curved type aluminum body and rib molding minimized Standing Wave. For the enclosure of speaker, you should focus to design interal resonance controlling. As PM103 are manufactured by extrusion molding process of pure aluminum, large and small rib are formed inside of product, we reduced effectively Standing – Wave of which resonance can cause sound degradation. Here, Front and Rear Baffle are connected with machine bolts which are specially processed, they can complete the enclosure with high durability. Even under big volume, it won’t generate distortion, which is originated from high quality design of enclosure as well as the excellent capability of amplifier and network circuit part. We adopted the amplifier with high performance and high efficiency 24K Gold Plated PCB Selected gold-plating PCB, designed signal pattern of the shortest distance, we eliminated all components which are unnecessary to signal terminal. For consistent quality, we restricted all resistance of signal terminal and control terminal to 1% level, used an audio grade electrolytic condenser of NXH standard (Low Impedance, Long Life) for power terminal. We used digital amplifier dedicated coil to output terminal, Audio Grade A curve 100k volume which was custom tailored to audio input terminal. Adopted inrush current protection circuit for protection circuit, we injected all available technology including POP noise eliminating circuit, high-voltage / low-voltage / high-current / high-temperature/ protection circuit to small body. To advance confidently to ‘reality’, the dream of audio, it is our effort only for sound. Final control for amplification of latter part (cross-over) Network plays a role to assign optimized frequency and quantity to each unit. Our company is possessing registered patent (Pat No. 0303476) related to technology. Excellent network circuit can perform speaker playing more flat without overlap section naturally. The key point of speaker sound is adequate frequency distribution at each unit covering high sound, low sound and its controlling. The second elaborated filter circuit of 12dB/oct provides high class PCB which is 24K gold plated. Additionally, we achieved significant improvement of signal quality by adopting oxygen –free copper (OFC) to coil part having long circuit channel. As network are matched and tuned at right back of amplifier in active system, we conduct the final control of sound by optimizing to amplifier.Exemplary configuration for Compact 2Way: 0.75inch + 4inch Even if unit configuration of PM103 has compact size, we can not only feel the composure of ultra low range but also it consists of poly dome tweeter of 0.75 inch and paper cone woofer of 4 inch which won’t miss even a single delicate expression. Furthermore, considering the feature of design having no front grill, for more dense low range, we adopted Acoustic Edge dust-cap. To draw excellent features of frequency during the development process, we repeated a number of adjustments, as a result, we made the acoustic performance of overwhelming scale which is unbelievable. Considering the features of amplifier which are influenced by the quality of power, we contributed the enhancement of performance by using linear analogue adopter of DC 24V power. You can expect full and rich sound quality without any gap among each note.  Speaker does not say in price or in shape. It only does in sound. Those who love music, sound and those audio files who are interested in sound quality, we Callas are developing and manufacturing a high performance speaker system with your concerns in mind and trying to inform as many people as possible. We are continuously researching to answer to your support with refined design and world-class performance models. The ‘sound’ is the thing for speaker above everything. In order to make the better sound, our technology developed obtained patent in July/2001 (Patent no. 0303476). The speaker is not completed from the mere experiences in sound; it proves that it is a product developed by the scientific methodology. Technically, it installed the passive network circuit that has a perfect slope characteristics (18dB/oct, 24dB/oct), and the sound is superior in resolution and the balance, we can proudly recommend our speaker. We can recommend our Callas speaker with confidence since we developed with everything as the mind with love for music, deep understanding in sound, tens of years of experience in sound business, etc. Desktop Active Speakers for Music & AVInternal Peak Limiter and Overload ProtectionAluminum Black or Silver Anodizing Active 2.7Kg  /  Passive 2.5KgPayment You can pay with PayPal using a credit card, bank card or your PayPal account balance.
