Sound Technology Debuts JBL's Marquis Dance Club Series Loudspeakers at PLASA As the distributor for all Harman Professional products in the UK and Ireland, Sound Technology Ltd will debut JBL's new Marquis Dance Club Series Loudspeakers at PLASA on stand E21. The Marquis Dance Club Series loudspeakers comprises eight models all designed to bring a new level of sonic excellence to dance club environments, the company says. The series incorporates new driver configurations and enclosure designs to deliver powerful, immersive sound with exceptional clarity and fidelity even at higher volume levels, the company adds Jon Sager, senior manager, installed sound, JBL Professional, commented, "JBL began offering loudspeakers for club use back in the 1970s, and JBL products helped define club sound when the industry was just beginning. The JBL Marquis Dance Club Series continues this heritage of innovation with a range of purpose-designed loudspeakers that bring high-impact sound to club goers who want to feel and hear all the excitement of the music." The MD1, MD2, MD3, and MD7 ultra-high, mid-high-frequency, low- frequency and subwoofer modules can be combined to create a complete five-way loudspeaker system that delivers extended high- frequency, high-frequency, midrange, bass and sub-bass capability, with frequency response down to 20Hz and the ability to effortlessly deliver high volume levels in large spaces. The MD1 provides frequency response from 8kHz to beyond 20kHz, the MD2 handles frequencies from 300Hz to 20kHz, while the MD3 provides frequency response from 80Hz to 300Hz and the subwoofer is capable of generating bass down to 25Hz. The JBL Marquis Dance Club Series MD46, MD49, MD52 and MD55 are stand-alone, full-range loudspeakers that can be used in a variety of room sizes and applications. The systems feature a distinctive grille design and system appearance, making them suitable for the interior décor of high-design club environments. The series' heavy-duty subwoofers, woofers, and midrange drivers employ JBL Differential Drive technology, which employs two voice coils and two magnetic gaps rather than the single drive coil of conventional drivers. This configuration provides higher peak output with less power compression, for consistent sound quality even at high volume levels, the company says. The subwoofers utilize JBL Vented Gap Cooling as well as Differential Drive technology, which pumps air through the woofer's magnetic gap and directly over and around the voice coil to provide immediate heat transfer and reduce operating temperature, further reducing power compression and enabling greater dynamic capability. The new 2453H-SL, 2432H and 2408H-1 compression drivers utilize lightweight neodymium magnet structures. The 2453H-SL utilizes a damped laminate diaphragm, facilitating smoother frequency response. All compression drivers operate in conjunction with JBL's exclusive Progressive Transition waveguides for high efficiency along with extremely low distortion and optimized pattern control. JBL's Selenium ST400 super tweeters offer articulate, long- throw high-frequency enhancement, making them ideal for use in clubs and larger venues. The MD52 and MD55 offer built-in handles, pole mounts and OmniMount-compatible mounting points, as well as multiple M10 attachment points and additional installation-friendly features.
