Review JBL Professional Series Model 4638th Serial Impedance Ohms Incorpora
The JBL 27818 4638 4-inch Dual-Concentric Dome Speaker is a high-performance audio solution for various applications, including home theater systems, professional sound reinforcement, and music production. This speaker is renowned for its exceptional sonic quality, advanced engineering, and versatile design.
At the heart of this speaker lies a 4-inch Dual-Concentric Dome design. The Dual-Concentric configuration places the tweeter in the center of the woofer, enabling the tweeter to radiate sound through the center of the woofer cone. This co-located design results in a more natural and detailed sound, as the high frequencies are not coming from a separate location but rather from the same point as the low frequencies.
The speaker features a 3rd Order (24dB/Octave) Linkwitz-Riley crossover, which is a sophisticated electronic filter designed to seamlessly blend the frequencies between the woofer and tweeter. This crossover ensures accurate frequency response while minimizing distortion and phase shift, resulting in a more cohesive and balanced sound.
This JBL speaker boasts a nominal impedance of 8 ohms, making it compatible with a wide range of amplifiers and audio systems. The impedance rating is not constant, though, and the actual impedance can vary between 3.2 and 16 ohms, depending on the frequency response. The 4638 model is designed to be efficient and can handle a maximum power handling of 100 watts RMS, making it suitable for use with both powerful and more modest amplifiers.
The speaker's frequency response ranges from 68 Hz to 21 kHz, covering the essential audible frequencies for music and speech. The sensitivity of the speaker is 88 dB (2.83V/1m), which indicates its ability to convert electrical power into sound energy efficiently.
The JBL 27818 4638 speaker is built with robust construction and high-quality materials to ensure durability and longevity. It features a polyester matte paint finish that not only looks aesthetically pleasing but also offers protection against environmental elements. The speaker's grille is made of aluminum and is magnetically attached to the speaker, allowing for easy removal for cleaning or replacement.
In summary, the JBL 27818 4638 4-inch Dual-Concentric Dome Speaker is a versatile and high-performance audio solution with exceptional sound quality, advanced engineering, and a sophisticated design. Its Dual-Concentric Dome technology, sophisticated crossover, and wide compatibility make it an excellent choice for various applications, from home theater systems to professional sound reinforcement and music production.
