4309
Designed and engineered in JBL’s world-famous acoustic engineering facility in Northridge, California, the 4309 Studio Monitor is a showcase of patented JBL acoustics technologies. This bookshelf loudspeaker features a 2-way design with patented High-Definition Imaging (HDI™) horn technology, the patented 2410H-2 1-inch (25mm) compression driver, and a 6.5-inch (165mm) cast-frame, Pure-pulp cone woofer for powerful dynamics and incredibly accurate sound reproduction.
JBL’s revolutionary High-Definition Imaging horn geometry is the result of intense research into the nuances of horn design. In search of exceptional high-frequency detail and uniform directivity for smooth in-room response, JBL engineers pioneered a design that delivers neutral frequency response both on- and off-axis and provides a seamless transition between the high and low frequency drivers.
The JBL 2410H-2 compression driver benefits from the advanced research and applications derived from JBL Professional’s “D2” range of transducers. At the core of the 2410H-2 device is a lightweight polymer, annular diaphragm that improve high-frequency extension by reducing diaphragm mass. The V-shaped geometry of the annular diaphragm reduces breakup modes, eliminating time smear and reducing distortion. The result is incredible dynamics with accurate reproduction and a lack of power compression.
An Ultra High-frequency tonal adjuster is located on the front panel below the horn and allows the sound to be tailored to the specific environment and listener preference. This control works in conjunction with an advanced crossover network design that features air-core inductors, cast wire-wound resistors and low-ESR metallized film capacitors to optimize the performance of the 4309 drive components.
The 4309’s powerful 6.5-inch (165mm) woofer takes advantage of core JBL engineering techniques to ensure very high output with low distortion. The long-throw voice coil in conjunction with the symmetrical field motor design, flux stabilization ring, and copper shorting ring guarantee maximum output with low distortion. A Pure-pulp cone provides a lightweight, rigid diaphragm and helps to eliminate breakup modes ensuring proper pistonic motion throughout the operating band.
The 4309 enclosure is heavily braced with 3/4-inch (18mm) thick walls to provide a solid acoustic foundation and incorporates a bass reflex design with dual front-firing, computer-optimized flared ports. The cabinet features a classic JBL studio monitor design with a blue baffle and is finished in a choice of Walnut or Black Walnut furniture-grade satin wood veneers. A blue (Walnut) or black (Black Walnut) cloth grille completes the elegant appearance. Dual sets of gold-plated binding posts provide a secure connection and offer a choice of single-ended or bi-wire/bi-amplified connections.

Dear colleagues from the press, You will find the latest press release of the HIGH END SOCIETY SERVICE GmbH below. We would appreciate if you will publish these news. In that case please send us a copy.
Kind regards,

THE HIGH END® 2021 IS NOW FULLY BOOKED!
The organizer is delighted about the strong exhibitor interest in the world’s leading audio trade show
The organizer of the event, the HIGH END SOCIETY Service GmbH, is pleased to announce that the HIGH END 2021 is now fully booked, even before the registration deadline at the end of March! After more than a year without events, this is sure to be music to the ears of exhibitors, trade visitors, consumers, media representatives and, of course, everyone involved in the success of the trade show during both the planning and implementation stages. The constant high demand for the sought-after exhibitor areas in the halls and atriums of the MOC Event Center in Munich clearly shows how keen the industry is to finally showcase its high-quality products to a live audience again after being starved of the opportunity for months due to the Covid-19 pandemic.
The HIGH END – an important provider of ideas and impetus on a global level
From September 9 to 12, 2021, the 39th HIGH END trade show in Munich will yet again shine the spotlight on excellent music reproduction, inspiring listening enjoyment and exquisite audio technology. For many years, the HIGH END has been providing both the big players in the industry and smaller owner-managed companies with their ideal presentation platform as the world’s leading audio trade show. It is the perfect place to establish business relationships, expand networks and exchange ideas and experiences with other industry experts. After trade shows all over the world were brought to a standstill by the pandemic, the international audio show now wants to further develop its high significance for the B2B area. “The second trade visitor day has attracted a consistently positive response”, reports Stefan Dreischärf, Managing Director of HIGH END SOCIETY Service GmbH. “We are very pleased about this situation and will do everything that we can to ensure that the HIGH END can take place in extremely safe conditions.” Dreischärf does, of course, regret that he will probably be unable to accept all registrations. As was the case in previous years, all further enquiries received for the HIGH END will now have to be placed on the waiting list given that the event is fully booked.
Safety in all respects
The September dates chosen for the event provide a high degree of planning reliability, which is likely to be particularly important for exhibitors and visitors from outside Germany. After all, current developments indicate that global travel will still be restricted in the early summer. Holding the trade show after the summer months allows more time for the advancing global vaccine rollout and the resulting immunization and containment of the pandemic. The wide variety of testing options now available increase confidence that events with a large number of participants will be able to be held by September. As can be expected, the event organizer has also developed a reliable and flexible hygiene concept that can be adapted to suit changing circumstances at any time.
Additional information:
The HIGH END is the undisputed international leader when it comes to impressively setting the tone for top-class music reproduction. The trade show has been providing ideas and impetus for producers, distributors, sellers and consumers of high-quality consumer electronics for four decades. Each year, representatives from the entire industry convene on four days at the HIGH END in Munich. From leading global players, right down to innovative start-ups, the exhibitors provide solid proof of their innovative verve, which they present to an international public at the HIGH END.
Few things are as divisive as audiophile spikes. Grounded vs. isolated. We have tended to encourage our customers to choose what they prefer by providing a standard M6x1 threaded receiver (which we will still have). If you are familiar with our history, we have circled between solid spikes, rubber feet, and at times shipped with both. As we continue to refine our products, the need for product feet that meet our level of performance and aesthetics has worked its way to the top of our to do list. Here is our solution. Now shipping on all new orders. If you would like to update your system with these feet, please contact your local dealer.
Features:
303 Stainless Steel Material Crafted in California Mechanical and electrical isolation Viton tipped Non-marking Oil and Chemical Resistant High Ozone Resistance Long-term elasticity Soft tip reduces chassis strain though better weight distribution
Product Compatibility** The Select Series The Reference Series The Premier Series The Discrete Series The DAC V Series The Analog DAC
**Product feet for the S500, M500, S202, and M204 that support higher weights will be coming soon.
