Stability and directional flexibility
The stability of audio products is critical. For high-end loudspeakers we generally pay more attention to the structure and materials of the cabinet. But even the best cabinets will inevitably transfer the vibration of the woofer to the tweeter.
To maximize electroacoustic performance, P Series engineers improved stability in three ways.
a. Low-resonance enclosure
Cabinet resonance directly affects the clarity of reproduced sound. To reduce or eliminate resonance, the size of the cabinet and its structural design are the keys. Using software to simulate the pressure and vibration states generated by component movement, our engineers identified the weak points of the cabinet structure under different frequency and amplitude regimes, continuously strengthening the structure and repeat testing, until these vibration points were eliminated. Sound pollution is thus minimized to improve fidelity.
b. Aluminum alloy, die-cast treble horn
Tweeter horns of most professional speakers are made of industrial plastic or resin (generally referred to as polymer materials), or stamped from thin steel plates. Due to the density of plastics and the thinness of stamped steel plates, the horn resonance points of these two materials are usually located within the tweeter’s operating range, generating undesirable vibrations. After precise modeling and design, the Starke Sound P Series team chose aluminum alloy for the horn enclosure. Structural ribs reinforce the entire horn for maximum stability and output power.
c. Vibration-damping swivel system
Professional photographers use the gimbal for vibration-free photography. Starke Sound employs this technology to further improve the stability of the AMTHorn. The internal structure of the directional gimbal and the Teflon material interrupt the sound “bridge” from the mid-bass speaker body to the treble horn. The vibrations of both sections are effectively isolated to avoid any interference. The gimbal has a rotation angle of 120 degrees from left to right, and a rotating shaft with mechanical damping. During theater calibration, a fixing device easily locks the AMTHorn into the required position for optimum dispersion.
P Series is introduced with five models: P9, P7, and P5 for main speakers, P3/P3i for surround speakers, and subwoofer. The P Series delivers high power and high sensitivity, and can be easily driven by a variety of power amplifiers on the market. For ultimate sound quality, we recommend the Starke Sound A series amplifiers.
“To defeat the opponents, you must break through yourself.”
After two-and-a-half years of research and development, Starke Sound's P Series professional private theater products definitely deliver the goods.
