KV2 Audio EX2.2有源超低音音箱

1000 Watt Dual 12-inch Subwoofer with current-enhancing Switch Mode technology

The EX 2.2 is a compact, high output active subwoofer system. Through the use of proprietary amplifier technology, precision manufactured, high-tech woofer designs and the innovative implementation of a high efficiency, twin chamber acoustic design, the EX 2.2 delivers tight, fast, controlled bass resp***e at very high levels. It falls directly out of KV2 Audio抯 philosophy to develop products with increased dynamic range, very high output and a c***istent sound character no matter what the output level. The system establishes new performance standa*** for a compact subwoofer that can only be achieved through the integration of new amplifier, transducer and electronic control technologies that are closely tied to a passion for taking performance to the next level.

The EX2.2 is can be used in a variety of system applicati***. It can add high performance bass reproduction to active speaker systems such as KV2 Audio抯 EX10 loudspeaker, or it can be easily used with passive speaker systems. The built in electronic high pass filter, phase and independent output level controls provide high precision, easy to use system integration circuitry.

Electronics
Amplifier power, electronic crossovers, equalization and speaker protection are integrated into the EX 2.2抯 amplifier module. On-board electronics ensures fast, easy set up, complete control making it easy to set up and long term reliability. An improved version of KV2 Audio抯 switch mode, current enhancing low frequency amplifier has been specially developed for the EX 2.2. The new design improves overall system efficiency to over 90% and delivers 1000 watts of continuous power.

KV2 Audio has developed an amplifier topology that delivers two unique characteristics that are critically important for high performance, active subwoofer systems. The EX 2.2 amplifier topology delivers very high efficiency and generates minimal thermal losses allowing the amplifier to deliver extremely high power levels reliably and simplifying the cooling system. Secondly, in order to reproduce low frequency information with high transient levels and extend the operational boundaries of the acoustic design, the amplifier needs to deliver an extraordinary amount of current in order to maintain the woofer under control. This is especially true under standard 損hase shift?conditi*** in which the amount of total voltage the amplifier can deliver is limited and the current requirement is sometimes doubled. Through the implementation of a unique, switch mode amplifier technology, the EX 2.2 amplifier delivers on both objectives, providing extremely high efficiency, low losses and delivering the highest woofer control by delivering higher current levels under 損hase shift?conditi***.

The electronics are fitted onto to a large format, finned, aluminum alloy heat sink providing high flow, passive cooling and eliminating standard maintenance cycles associated with forced cooled amplifier designs. The entire mechanical assembly is fitted on a mechanical suspension system that isolates low frequency energy and ensures long term reliability.

Acoustic Components
The EX 2.2抯 woofer technology is based around high efficiency woofer designs. The devices feature, high temperature polymide voice coil assemblies that undergo multiple baking and curing processes as well as advanced magnetic structures with complex cooling systems. The woofer cones h***e been specially developed to withstand the demanding environment created by the high loading inside the EX 2.2.

The EX 2.2 was designed using new concepts in twin asymmetrical acoustic chambers that deliver very high speaker loading and output from a relatively ***all cabinet footprint. It is ideal for use in live applicati*** that require reproduction of low frequencies with very high transient content at high output levels.

Enclosure Design
The EX 2.2 is a very compact, lightweight enclosure featuring a number of ergonomically designed parts that make it an easy system to set up and use. KV2 designed and tooled a new very compact 搒ide handle?that is recessed into each side of the cabinet. There are eight custom molded, low friction feet placed at the bottom and back of the cabinet. Routed 揻oot?cutouts allow easy stacking.

There are two industrial grade, internal braces placed at the top of the cabinet. Each brace is held in place by four M8 bolt and feature two M10 hang points providing a wide range of installation and suspension flexibility. There is also a pole mount 搕op hat?located at the top of the cabinet.
