音箱技术参数详解
音箱技术指标解析时下许多音响指标良好，却不忍卒听；而有些听音尚可，却经不起客观的物理测试。
音响指标日益飙升；音乐感情表达能力除除下降。
这些是事实，特别是国内的产品。
LP的指标几乎不及格，可是还有好多发烧友去追求。
我也来说说楼主所说的7个问题，当然也只能代表我个人的观点！大家有什么不同的看法也希望大家说出来一起分享！1．频响范围从声学的角度来说，声音是以波的形式存在并且传播的，而波是振荡的，因此波的单位是Hz（每秒钟振荡的次数）。
声波的Hz数值越小，声音就越响；Hz值越大，声音就越小。
从人耳的结构而言，理论上最轻听到20000Hz的声音（但在现实生活中几乎很少存在），而一些动物则可以听到更高Hz数的声音，如狗据称可以听到50000Hz。
音箱的频响范围是指该音箱在音频信号重放时，在额定功率状态下并在指定的幅度变化范围内音箱所能重放音频信号的频响宽度。
通俗的说，就是音箱所能发出的最低音和最高音之间的范围。
一般来说放大器在规定的功率状况下，在频率的高、低端增益分别下降-3dB，两点之间的频带宽度称为该放大器的频响范围。
没有仪器我们也能测试，用人的耳朵去测量不仅仅测量了器材也测量了您的耳朵，先告诉大家不同的器材上去测量您听到肯定不一样，器材直接是有误差的。
好的机器误差不大，国产不知名的东西就难说了，如：《雨果发烧碟1》有25Hz-20kHz测试信号。
器材能发出的频响是不一样的，人的耳朵接受能力也不一样，有时候自己没有听到不是它没有发出声音，是您听不到那断频率，我想很多发烧友都测试过自己的耳朵。
人能听到的音频信号大约20Hz~20kHz之间的不同频率、不同波形、不同幅度的变化信号，而事实上那是人一出生时耳朵能听得到的频率范围，２０岁以后就越来越窄了，大约在35Hz~18kHz。
您的耳朵能到到在哪一段还是去测量一下吧！2．灵敏度灵敏度是衡量音箱效率的一个指标，它与音箱的音质音色无关的。
普通音箱的灵敏度一般在85—90dB(分贝)之间，有的则可以达到100dB以上。
HD5250 HD5250SE HD7180 HD7400纯功放产品综述
本文档包括WINNER HD5250 WINNER HD5250SE WTS HD7180WTS HD7400WINNER HD5250 250W5声道全平衡HIFI/AV大电流后级高档纯前后级给出声音的细节感和解析力，清澈见底，这是可能玩过前后分体功放的朋友后不想再玩A V合并机，声音的质和量在前级中完美体现，在大功率后级强有力的推动下，让扬声器尽情欢叫。
前级出声，后级出力，便是其中的道理。
在全新多声道环绕效果解码器AD7100N问世之后，同时也针对高端玩家对于多声道音响系统性能的需求，推出这款拥有5声道，每声道250W输出功率(8欧姆)，在4欧姆阻抗下，最高每声道可输出440W的大功率HD5250后级顶级扩大机。
庞大外型与34.2的标称重量，本机确实相当有份量。
不过黑色精致的机身，与简洁突出的三角线条，巧妙柔化原本理应的器材笨重感，反而塑造出別具风味的精品美感。
HD5250提供5声道RCA与平衡式XLR输入，内部电路设计采用大电流功率设计,由于各声道均配有独立线路，以及正负放大电路分开处理，遂能有效降低内调失真的音质劣化影响，在大动态下播放复杂乐段与紧凑配乐音效时，各声道均能表现出清晰透明的音色，以及更为细致逼真的解析细节。
同时，采全对称、架构亦能有动态大、驱动力强、转换速率高、掲波失真小、低噪音、瞬態回应好、线性度高等好处。
以确保扎实浑厚的低频包围感，以及更为石破天惊、震撼人心的多声道音场效果。
作为全新的后级扩大机HD5250，拥有极大功率的输出能力，几乎能轻松应付50-100平方空间，及大型音响系统。
30平方的小空间一样合适,在其强劲、快速的驱动能力，对于一般低功率扩大机均捉襟见肘、难以推动的低效率、多单元喇叭，也能发挥令人满意的音响效果。
当然，对于能拥有如此顶级规格的后级，不妨就让HD5250搭配全新AD7100N多声道环绕效果解码器，满足您期待已久的高音质、高品质的家庭剧院效果吧。

Teufel System4音箱系统试听评测
小房间THX影院代言人Teufel System4音箱系统试听评测文/老蜗牛在很多人的印象里，家庭影院就是买套音响配个微投或者平板电视就可以了，甚至认为卖个DVD播放器接上电视就是家庭影院，这重观点甚至被很多社会媒体认同并刊发这类文章，误导了很多不明真相的吃瓜群众，导致很多人来问我家庭影院相关问题时候还要普及一遍基础知识，心累香菇。
我想说的是，家庭影院是一个严肃的系统，传统的家庭影院概念，从字面意义上了解，就是在家里面享受电影院的效果。
而《家庭影院用环绕声放大器通用规范》则指出：只有由环绕声放大器(或环绕声解码器与多通道声频功率放大器组合)、多个(4个以上)扬声器系统、大屏幕电视(或投影机)及高清晰度多声道节目源构成的,具有环绕声影院效果的家用视听系统才能称为家庭影院。
不是随便买一个蓝光机或者买个回音壁也能叫家庭影院的，国家有执行规范，国际上也有认证标准，比如业内著名的THX（Tomlinson Holman Experiment的字头缩写），美国LucasFilm 卢卡斯公司制定的私人影院技术规范。
早期的电影院水准参差不齐，当年老乔（《星球大战》及《夺宝奇兵》的导演乔治•卢卡斯）在影院里看了自己的作品之后感觉相当不满意，他希望影院能真实还原出自己的作品，于是就有了后来的THX影院标准，THX是一种对电影、播放设备、播放环境等的认证标准，是世界公认的最高标准，包括对环境噪音、图像亮度、声压级和音箱、功放品质、座位舒适度等标准要求。
THX标准私人影院将如实重现电影导演想要带给观众最真实的影片场面，享受原汁原味的视听盛宴。
THX精神最佳阐述者因为进入中国不久，提到德国Teufel可能有些人并不太熟悉，但是在德国乃至世界范围却是大名鼎鼎了，金耳朵等各种评奖拿了很多，CARA等著名声学设计软件中都内置了Teulel的产品数据。
作为美国THX官网推荐的音响品牌，1996年成为德国第一家通过THX认证的音箱生产商，旗下有世界上最多的THX认证家庭影院音箱产品，有世界上最小的THX认证家庭影院音箱产品，而且不但音箱通过了THX认证，配套的低音炮同步通过了认证。

Nearly every connection is located exclusivelyon the active speaker. This speaker provides signal and power for thepassive speaker. The exceptions are the bare-wire connectors, which sendpower and signal from the active speaker to the passive speaker.2.1 Rear Panel2.1.1 InputsLine-level Inputs. The Eris active speaker provides a choice of two pairs ofinputs on the rear-panel: left and right balanced ¼” TRS and left and rightunbalanced RCA. These inputs accept a line-level signal from an audiosource and feed that signal to each monitor’s power amplifier. These inputsare provided to enable flexible connectivity, not for connecting multiplesources to your speakers simultaneously. A third 1/8” stereo input is availableon the front panel, please see Section 2.2 for more information.Power User Tip: The left inputs (balanced or unbalanced) send signal to the amplifierthat powers the active speaker; and the right inputs send signal to the amplifier thatpowers the passive speaker. PreSonus recommends that the active speaker be placed onthe left side of your mixing space and the passive speaker be placed on the right.However, if you prefer to have the controls located on your active monitor placed on theright side of your workspace, be sure to reverse the inputs from your audio source tomaintain the correct stereo image.2.1.2 PowerIEC Power Connection. The Eris active speaker accepts a standard IEC C7 powercord. The power switch is located on the front panel of the active speaker.2.1.3 Acoustic Tuning ControlsHigh. Boosts or cuts all frequencies above 10 kHz by ±6 dB.Power User Tip: The High control is a high-shelf EQ and attenuates or boosts frequenciesabove 10 kHz. This EQ is much like the treble control on a home or car stereo: It raises orlowers the gain on all frequencies above the specified cutoff frequency. Shelving EQs canmake big changes to the sound very quickly by adding or removing an entire range offrequencies.Low. Boosts of cuts frequencies around 100 Hz by ±6 dB.Power User Tip: The Low control is a low-shelf EQ and attenuates or boosts frequenciesbelow 100 Hz. This function is the equivalent to the Bass control on a home or car stereo:It raises or lowers the gain on all frequencies below the specified cutoff frequency.Shelving EQs can make big changes to sound very quickly by adding or removing anentire range of frequencies.2.1.4 Speaker ConnectionsBare-wire connectors. This connection is used to send power and send signal tothe passive Eris speaker. Be sure to connect the positive and negative connectionson your active Eris speaker to the positive and negative connections, respectively, onthe passive Eris speaker (i.e. connect positive to positive and negative to negative).2.2 Active Speaker Front PanelPower Switch. This is the On/Off switch.Power / Bluetooth Status LED. The LED above the volume control indicates powerstatus for all Eris speaker models. For Eris E3.5 BT and E4.5 BT reference monitors, thisLED also displays the Bluetooth status as follows:•Solid Blue. Eris speaker is powered on.•Flashing Blue (Eris E3.5 BT and E4.5 BT only). Eris speaker is in pairing mode.•Solid White (Eris E3.5 BT and E4.5 BT only). Eris speaker is paired to aBluetooth device.Volume. Sets the volume level of the input signal before it is amplified. This is alsothe volume control for the front-panel headphone amp.Aux In. This stereo 1/8” jack can be used to patch in a media player for a quickreference check.Power User Tip: This input will sum with the inputs on the back panel.Headphone Out. This headphone output is controlled by the Level knob.Power User Tip: When the headphone output is connected, audio will be muted to yourEris speakers. So, you can listen as loud as you like without disturbing the neighbors.3.2 Audio Connections3 Hookup Diagrams3.3 Bluetooth Pairing (Eris E3.5 BT and Eris E4.5 BT only)Eris®-series E3.5/E3.5 BT/E4.5/ E4.5 BTOwner’s Manual3.3 Bluetooth Pairing (Eris E3.5 BT and Eris E4.5 BT only).You can pair an additional device by repeating these steps.

If it’s connected toa power conditioner, verify that the power conditioner is turned on and functioning.No audio. If your active Eris speaker appears to power on but you hearno sound when playing audio from your audio source (the lights are onbut nobody’s home), first make sure that the cable connecting your audiosource to the active speaker is working correctly. Also, verify that the volumecontrol is set to provide enough amplitude for the signal. If only the passiveEris speaker is not passing audio, check your speaker-wire connectionsand verify that the bare wire is fully inserted into each connection.Hum. Usually, hum is caused by a ground loop. Verify that allaudio equipment is connected to the same power source.Sound is thin. If the sound of the speakers seems thin and brittle, checkthat your speaker wires are connected correctly (i.e., the positive/redconnection on the active Eris speaker is connected to the positive/redconnection on the passive Eris speaker and the negative/black connectionon each is connected to the negative/black connection on the other).Dinner is ServedAdded bonus: PreSonus’ previously Top Secret recipe for…Chicken and Andouille GumboIngredients:• 1 C All-Purpose flour•¾ C Vegetable Oil• 1 large onion (diced)• 1 small onion (quartered)• 6 celery stalks (diced)• 1 large green bell pepper (diced)• 3 cloves garlic (2 minced, 1 whole)• 1 lb link Andouille sausage• 4 Chicken leg quarters• 4 qt water• 4 bay leaves• 1 tsp thyme• 1 tsp Old Bay seasoning•1-2 C frozen okra, sliced•¼ C fresh parsley, minced• 6-8 eggs (optional)Cooking Instructions:1.

mode7.Instructions and factory parameters7.1Instruction formatThe module supports software version reading,and it can be read through the serial port in the transceiver mode(when7.2Factory default parameters8.Hardware design●It is recommended to use a DC stabilized power supply.The power supply ripple factor is as small as possible andthe module needs to be reliably grounded.●Please pay attention to the correct connection of the positive and negative poles of the power supply,reverseconnection may cause permanent damage to the module.●Please check the power supply to ensure that between the recommended supply voltage,if exceeding the maximum,the module will be permanently damaged;●Please check the stability of the power supply.Voltage can not fluctuate greatly and frequently;●When designing the power supply circuit for the module,it is often recommended to reserve more than30%of themargin,so the whole machine is beneficial for long-term stable operation;●The module should be as far away as possible from the power supply,transformers,high-frequency wiring and otherparts with large electromagnetic interference;●Bottom Layer High-frequency digital routing,high-frequency analog routing,and power routing must be avoidedunder the module.If it is necessary to pass through the module,assume that the module is soldered to the Top Layer, and the copper is spread on the Top Layer of the module contact part(well grounded),it must be close to the digital part of the module and routed in the Bottom Layer;●Assuming the module is soldered or placed over the Top Layer,it is wrong to randomly route over the Bottom Layeror other layers,which will affect the module's spurs and receiving sensitivity to varying degrees;●It is assumed that there are devices with large electromagnetic interference around the module that will greatlyaffect the performance.It is recommended to keep them away from the module according to the strength of the interference.If necessary,appropriate isolation and shielding can be done;●Assume that there are traces with large electromagnetic interference(high-frequency digital,high-frequency analog,power traces)around the module that will greatly affect the performance of the module.It is recommended to stay away from the module according to the strength of the interference.If necessary,appropriate isolation and shielding can be done;●If the communication line uses5V level,a1k-5.1k resistor must be connected in series(not recommended,there isstill a risk of damage);●The antenna installation structure has a great influence on the performance of the module.Make sure that theantenna is exposed and it is best to be vertically upward;●The mounting structure of antenna has a great influence on the performance of the module.It is necessary to ensurethat the antenna is exposed,preferably vertically upward.When the module is mounted inside the case,use a good antenna extension cable to extend the antenna to the outside.●The antenna must not be installed inside the metal case,which will cause the transmission distance to be greatlyweakened.9.FAQ9.1Communication range is too short●The communication distance will be affected when obstacle exists;●Data lose rate will be affected by temperature,humidity and co-channel interference;●The ground will absorb and reflect wireless radio wave,so the performance will be poor when testing near ground;●Sea water has great ability in absorbing wireless radio wave,so performance will be poor when testing near the sea;●The signal will be affected when the antenna is near metal object or put in a metal case;●Power register was set incorrectly,air data rate is set as too high(the higher the air data rate,the shorter thedistance);●The power supply low voltage under room temperature is lower than recommended value,the lower the voltage,thelower the transmitting power;●Due to antenna quality or poor matching between antenna and module.9.2Module is easy to damage●Please check the power supply source,ensure it is between the recommended supply voltage,voltage higher thanthe maximum will damage the module.●Please check the stability of power source,the voltage cannot fluctuate too much.●Please make sure antistatic measure are taken when installing and using,high frequency devices have electrostaticsusceptibility.●Please ensure the humidity is within limited range,some parts are sensitive to humidity.●Please avoid using modules under too high or too low temperature.9.3Sound quality is too bad●The power supply ripple is too large,so be sure to reduce the power supply ripple,increase the decoupling capacitor,and increase the EMC filter circuit;●The audio input wiring is unreasonable,and it needs to be differentially designed and as close as possible to themodule pins;●The audio input wiring is unreasonable,and it needs to be differentially designed and as close as possible to themodule pins;●There may be co-channel signal interference nearby,modify the module channel usage;10.Welding operation guidance10.1Reflow soldering temperature10.2Reflow solderingcurve11.Related models12.Antenna
