?KV2 Audio EX12有源全频音箱产品描述
&&&& 500 Watt Extreme Resolution Speaker System The EX12 is a two-way high output, active, compact, full-range speaker system. EX12 design objectives focused on the expansion of KV2 Audio’s primary philosophy of increased dynamic range, very high output and a consistent sound character no matter what the output level. The advanced 3.00-inch compression driver and horn assembly provide extended throw capability from a compact enclosure while 500 watts of on-board amplification and an advanced woofer technology deliver solid bass reproduction at high output levels.
The EX12 sets new levels of performance for compact cabinets achieved through the integration of new amplifier, transducer and electronic control technologies that are closely tied to KV2’s passion for taking performance to a higher level.
APPLICATIONS
Small to medium-sized Live and Playback Applications Portable PA Systems for speech and multimedia playback Mobile DJ (when used with EX2.2 or EX 2.5 Active Bass Modules) Floor Monitoring Applications Fixed Installations that need to rock
High-output, extreme resolution, compact full-range speaker system 127 dB sustained output with very high dynamic range and low noise floor Integrated active amplification and control electronics with 500 total watts of power Complete, on-board speaker system management including equalization, time correction, crossover filters, amplifier overdrive protection, system set-up and output level controls Very high quality 50-watt, low IM distortion Class A/B high frequency amplifier with transformer-balanced output provides comprehensive distortion control under clipping conditions 450-watt high current, high-efficiency low frequency amplifier delivers high output bass with total control. Compact asymmetrical trapezoidal cabinet design allows for use in stage monitor or under balcony applications. New, state of the art 3.00” (76mm) diaphragm titanium compression driver features the first diaphragm to be treated with a Nitrate Vapor Particle Deposition (VPD) process that dramatically improves the dome’s resonance and dampening characteristics lowering distortion and extending frequency response. The driver features the largest neodymium motor in use today providing absolute control of the diaphragm assembly. Wide dispersion (80° horiz. x 40° vert.) Floor Monitoring Filter precisely adjusts equalization and phase response characteristics providing optimized monitoring performance. Twelve-inch woofer with revolutionary Active Impedance Control (AIC) voice coil technology and neodymium magnetic motor structure dramatically increases force, lowers distortion and provides increased frequency response linearity. Professional, Baltic birch construction with wear resistant polymer coating Proprietary top/side handle design for simplified handling and carrying integrates one M10 hang points, OmnimountTM bracket point and four M6 bracket points Two side-mounted M10 hardware points Top hat for pole mounting applications
ElectronicsAmplifier power, electronic crossovers, phase alignment, equalization, time correction and speaker protection are integrated into the EX12’s amplifier module. On-board electronics ensure fast, easy set up and complete control. The low frequency amplifier is a high efficiency, high current design especially developed for the EX12. This new topology improves overall system efficiency and increases output allowing passive radiation of heat to take place through a unique “fin-less” heat sink that can be placed in any position or direction. This ensures cool operation in horizontal or vertical applications. Additionally, the EX12 amplifier unit contains an internally located electric fan that is operated by a temperature sensing circuit which will slowly bring the fan online as required in extreme, high temperature situations.
Months of research were invested into designing circuitry to ensure that the EX12’s extreme dynamic range is maintained even under clipping conditions. The real test of the EX12’s limits is when it is exposed to the rigors and demands of live audio playback where clipping of amplifiers, generation of distortion artifacts and dramatic increases in the noise floor are all par for the course.
The EX12’s high frequency amplifier uses KV2 Audio’s standard low intermodulation distortion, Class A/B, push-pull topology. Metal Oxide Silicon Field Effect Transistors (MOSFET) are used for the output stage while the compression driver is coupled through a transformer balanced speaker output. The performance strategy for this type of design is based on producing the lowest intermodulation distortion possible and providing a technique for control of distortion by-products generated by the amplifier under clipping conditions. This provides the highest level of performance and audio quality possible. Acoustic ComponentsThe compression driver is a new, 3.00-inch (76mm) titanium diaphragm design, featuring a radial phase plug, progressive parabolic semi-circle suspension, direct drive nomex voice coil assembly and the industry’s largest neodymium magnetic motor structure. The largest advancement has been made through the development of a new treated titanium material used in the dome assembly. Through Nitrate Vapor Particle Deposition (VPD), an additional layer of material is fused to the titanium at a molecular level. The resultant material has dramatically improved resonance characteristics and improved dampening resulting in lower distortion artifacts and improved frequency response linearity extending the driver’s response beyond 20kHz.
The EX12 horn design was designed with two primary design goals. First to be as smooth as possible within its operating bandwidth and second to display perfect power response characteristics vis-à-vis the 12-inch woofer it is designed to crossover with.& The horn design is based on constant- directivity geometry with an emphasis on generating very low air distortion artifacts, maintaining low transducer compression ratios, high output and wide dispersion (80° x 40°). The horn is an injected molded aluminum part that functions as a heat dissipator for the compression driver’s neodymium magnetic motor structure.
Both the compression driver and the woofer technologies were developed in conjunction with the engineering team at KV2 Audio’s transducer partner, 18 Sound in Cavriago, Italy. A new woofer technology has been developed called Active Impedance Control (AIC) and it delivers several exciting performance advantages. AIC technology consists of a carefully designed and placed “additional” coil placed on the speakers’ magnetic pole piece and connected in parallel to the primary voice coil. The magnetic field generated by this additional coil has the following effects: 1) Complete linearization of speaker impedance2) Linearization of the acoustic and electrical phase response3) Delivery of a significant increase in sensitivity and total SPL output4) A remarkable reduction of Total Harmonic Distortion (THD)5) Increased power transfer and transducer speed All of these benefits help minimize several weaknesses inherit in two-way loudspeaker systems such as poor quality low-mids and the poor transient response found in this band pass. The EX12 is transparent, up-front and seamless in comparison to any and all competitive active 12-inch two-way designs.
Enclosure DesignThe EX12 is a very compact, asymmetrical geometry enclosure design allowing it to be used in a variety of applications and featuring a number of ergonomically designed components that make it lightweight and easy to use. An extensive set of professional hardware features enables the EX12 to be used in a variety of environments using an array of industry standard hardware. These facilitate both portable and fixed installations with a maximum amount of mounting flexibility. A specially molded aluminum handle was designed and fitted to the top and side of the cabinet. It functions as the principle pick up handle as well as providing several fixed installation and hanging solutions. It has a centrally located M10 hang point as well as four additional M6 bracket points. The handles four principal mounting bolts also provide an OmnimountTM bracket point. There are two side-mounted M10 hang points that can be used with brackets or eyebolts. AccessoriesEX2.2 Active Bass ModuleThe EX12 can be combined with an EX2.2 Active Bass Module in order to create a formidable, very high output audio system. The EX2.2 is comprised of two 12-inch woofers and features on-board amplification and control electronics with 1000 watts of total power and can be easily connected to the EX12 through the internal control electronics.
EX2.5 Active Bass ModuleThe EX12 can be combined with an EX2.5 Active Bass Module double 15-inch systems as well. The EX2.5 is comprised of two 15-inch woofers and features on-board amplification and control electronics with 1600 watts of total power and can be easily connected to the EX12 through the internal control electronics.
EX12-HBracketA horizontal U-bracket designed for use with the two side-mounted M10 hang points. EX12-VBracketA vertical U-bracket designed for use with the top handle located M10 hang point. The kit includes a special mounting plate with integral M10 attachment point that replaces the lower top hat assembly.

05-16【讨论】304要被砍了，你们有什么说的么
反正楼主的304已经打腻了。毛子为什么不砍法系五级金币小火炮麽？昨天半血护国公去偷火炮时差点被它和44反艹。
　-------- 如梦令：自行火炮(&﹏&)我有重炮一挺，口径大如水井，百里穿云过，天上掉下馅饼，灌顶，灌顶，把你炸出阴影↖(^ω^)↗炸哭你们，炸炸炸～Y(^_^)Y

我自己就有304，看到对面的304除非正好被他刺了，根本不用怕，说304恶心的基本都是按照常规防炮位的二货
砍就砍咯 反正只是个娱乐的小车
拍手称快！大快人心！
被圈过来。。。。看看。。。
法国五级金币那个不打脆皮，伤害全是100左右，机动翔一样，不算逆天吧
砍了？我那车早已满身灰尘
大快人心，这火炮打不死人，把人恶心死。
砍了什么？
砍射程吧2333真不行我就去玩B2炮，真•断腿到死
昨天和基友俩304组队，砸得对面卡那封直接白字开骂。【反正等新版本出来，估计也玩腻了～
其实只是恶心人又不op，灯泡没出，不砍机动我就留了。
昨天刚刚卖，今天起来看qa就说要砍，什么情况
兄弟信我的话，—3绝对好车，当初我刚刚出—3时候玩了一下，感觉各种脆皮，各种坑，但是慢慢熟悉之后，才知道—3真是难得的好车！已经玩了500多场，我现在有虎王，有—3，整体感觉，—3的战场适应能力要比虎王强多了，我现在的—3进10级房都能保证打出场均1500，整体场均应该超过2300了，真的是虎王不能比，想把—3玩好要记住扬长避短，—3的机动，单发伤害，还有危及时刻那个大家所谓的侧面（其实那是—3的履带后面的底盘距离地面很高，所以实际侧面投影很小，容易打到履带后面没有装甲的地方，即使打得地方有装甲也容易被履带吸收伤害），这些都是—3的杀手锏，掌握—3的多种伸缩技术，以及一些中坦偷炮的方法，你会发现这个车真的很厉害！
砍拉我就当轻坦玩，不怕不怕
快砍，被304恶心得不能自理了！
304我已经过了 砍吧 砍死
因为流氓火炮比较低调
刚刚练到主教……
首先没有304，。其次。好！好！好！！！！！
上个月上了3涂
法系的散布 都不用坎 次 都不带打到一个点上的
6级可以砸不会走位的sb的火炮多着呢，砍就砍吧玩m44，野蜂一样可以19s一发教各种小朋友学做人
我还没玩过这个车　　　　　　　　　　　　　　　　　　　　　　　　坑车终结者，不服来练。
昨晚上刚出，履带都还没打出来咧
刚买才撸了30多场。。。。主教没点炮，出了炮后场均1200了，貌似
