The CV5028S subwoofer boasts highly dynamic, fast transient response with less low frequency descension. Outdoor extended low frequency performance is reinforced with legendary JBL subwoofer tuning, high-quality, low frequency response can be achieved. The CV5028S is a compact and powerful waterproof subwoofer with JBL Black DuraFlexTM finish. The 18" low frequency woofer is equipped with two high power 460 mm driver for optimal low-frequency performance. It can maintain linear even output at high volume level. Its inner structure design allows suspension.

Some of the advanced low frequency technologies are used for the CV5028S. Its unique and innovative design enhances mutual coupling of two drivers. In addition, enhanced coupling between the drivers accelerates transient response while optimizing energy efficiency entirely. The system equipped with two high-power (460 mm) drivers for optimal low-frequency performance that reduces distortion and have extremely symmetrical and flat inductance curves. The solid copper 100 mm (4") voice coil is wound in two different layers, supported by inner and outer coils, to integrate double exposure which is good for air cooling. Hence it allows increasing long-term heat resistance. Each cone is made of very hard fiberglass reinforced paper empowering invincible waterproof performance.

The subwoofer cabinet features 18 mm birch plywood to ensure solid sound. Recessed handles are included for easy carrying. Two Neutrik® speakONTM NL4 waterproof connectors are provided for input and loop-through connections. The CV5028S employs an innovative subwoofer design with unprecedented "powerful" low frequency performance. Stateof-art technology is integrated into CV5028S to ensure driver performance and accurate acoustic transient response to ensure unprecedented low frequency reproduction quality and less descending low frequency response, as well as extremely fast and accurate bass response.

特点

Rigging System
The top of the speaker cabinet includes M10 hoisting points, which can be used by hoisting accessories, and a removable non-slip plastic pad is installed at the bottom.

Waterproof
The CV5028S includes waterproof connections to support complex indoor and outdoor installation environments, eliminating concern about electronic component damage, due to moisture and rain.

System Solution
The CV5028S combines a high-quality low-frequency loudspeaker system for indoor and outdoor environments. Therefore, the low frequency is greatly extended for the CV5000 Series products, and a low frequency limit of the loudspeaker system is supplemented.

Performance
The CV5028S is an ideal choice for a performance system with additional peak output, making it ideal for concert touring and music applications, requiring higher-level, low frequency response, which is achieved by using unique JBL speaker technology and two independent voice coils.

JBL continually engages in research related to product improvement. Some materials, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description but will always equal or exceed the original design specifications unless otherwise stated.
