一個厲害的生活達人，強的地方不是很會做菜或整理家裡
而是很會"使用工具"!!!!!!!!!!!!
尤其許多家電設備
懂的人來使用，不僅增加生活便利性，同時招待朋友也有聊不完的話題
但是選擇家電人人都會，重要的是安全性該怎麼挑
包括有：1. 產品的溫度或壓力過高引起的起火自燃甚至爆炸，這通常起因於產品的結構設計不良，所以針對發熱類的家電產品，UL會進行「正常運作的溫升測試」及「抗壓力測試」，藉此確認產品在運作時溫度是否會產生異常、是否會超過各元件的耐用溫度；及透過模擬倍增壓力測試，來確認產品於運作異常情況下，其產生的高壓力是否可被控制，以避免潛藏危險發生的可能。
另外，2. 馬達類產品，如果汁機、生機調理機、 吸塵器、風扇…等，最怕出現馬達過載問題。據UL表示，因為馬達運作類產品，在馬達鎖死的狀況下，啟動後可能會產生高達1000安培的瞬間負載，若通電時間過長，將可能引發馬達過熱起火狀況。因此馬達類產品除「正常運作的溫升測試」，另一個重點是「馬達堵轉測試」，主要是確認產品於馬達運作異常情況下，馬達保護元件是否可有效地在起火發生前運作，避免危險發生。
總體來說，家電產品涵蓋了以下的安全檢驗重點：「電擊傷害的防護」、「能量傷害的防護」、「火災的防護」、「熱傷害的防護」、「機械傷害的防護」。而對於家電產品會碰到的電路電源、甚至是外殼與電源線的設計，也都要有完整、嚴謹的檢驗程序與高度的安全要求。
▲材料必須進行火焰測試，確認材料的耐燃等級，以應用於產品上。
挑選安全認證家電有眉角
提醒大家幾個要注意的地方：
選擇商譽良好的品牌。 如果在經費許可的情況下，當然建議消費者還是購買大廠牌產品，畢竟廠牌大就比較不敢取巧或疏忽，品牌做得愈大，對於自己的信用也會愈小心一些。
現在各種大小賣場到處都是，網路購物平台也一個接一個，雖然網路購物很方便，也知道許多台灣消費者常上淘寶撿便宜，但還是請千萬小心，即使是網路購物，一樣要找知名的網路通路、電商平台，對自己才會比較有保障，畢竟公司做得愈大，愈不容易隨便拿自己的商譽開玩笑，真有糾紛發生，也比較容易求償。
看一看有沒有認證標誌。但大家也可能會有疑慮，是不是大廠牌就一定沒問題？還有沒有其他可以更嚴格把關的方法？品質的定義繁多，安全性就是其中最重要的一環，少了安全這項前提，不管產品再創新、功能再強大都顯得毫無意義！小編建議可以檢查看看產品外觀底部有無相關認證標誌的印刷，不同產品可能有不同的項目認證或是地區的認證如 CE, UL, BSMI 等等，這些經過嚴格測試認證的產品，相對而言保障也加分許多。

產品描述:
At the heart of theater is the human voice. Our ears are most attuned to catch every subtle nuanceof this expressive instrument.
Being the hardest working speaker in a surround system, the quality level of a center channel is ofmajor importance to a system. Film sound springs to life from the Maestro Grand with a naturalnessand intensity to match any of the Vienna Acoustics Grand main speakers. This extraordinary centerspeaker features an iris-shaped tweeter mounting block that allows this advanced 1" silk dome tweeterto work in perfect harmony with the dual 6" mid-bass drivers, utilizing Vienna Acoustics' proprietarySpider Cone technology, in order to offer unrestrained dynamics and unparalleled detail in giving voiceto even the most sophisticated of theater systems.
Handcrafted enclosures in beautiful wood finishes define the Vienna Acoustics aesthetic. The GrandSeries features the following selections to complement any interior: Piano black, Maple, Cherry, andRosewood.
Absolutely new is Maestro's tweeter, an implementation of the technologyfound in the ultra high-end reference center channel, ORATORIO. The 1"silk-dome tweeter incorporates a triple stack neodymium magnet assemblymounted within an integral decoupling iris-shaped mounting block toreduce any extraneous resonance. Housing the tweeter in this assembleallows the tweeter to be positioned above the mid-bass drivers, assuringexceptional dispersion characteristics, as well as open and effortless highfrequency response.
The two new 6" mid/bass Spidercone drivers used, based on the 7"reference driver found in BEETHOVEN Concert Grand, offer perfectbass dynamics combined with clear and natural midrange performance.
The development of this driver was made possible by the experiencegained in the development of X3P, which is a cone material that blendsVienna Acoustics exclusive TPX polymer and three polypropylene basedsynthetics to allow for maximum inner damping for midrange clarity, whilethe spidercone ribs provide maximum stability for bass impulses. Finally,these drivers benefit from a new inverted rubber surround design thatconstitutes a breakthrough in no loss damping of cone edge resonances.MAESTRO uses two of these unique drivers, combined with dual frontports, for ultra-fast, linear, and muscular bass extension to 38 Hz.
MAESTRO is 100?hielded.
A completely new linear crossover layout, with the copper circuit pathsarranged in the direction of electron flow, takes into account the potentialfor sympathetic and parasitic interactions among crossover componentsthat may inject unwanted noise and distortions while allowing for moredirect and efficient transfer of signal to the drivers which leads to a greaterlevel of detail and purity.
New proprietary cabling, consisting of large scale solid copper conductors,with each cable pairing precisely twisted a prescribed number of turns forthe particular length of each cable so that any noise injection through thewiring harness is avoided.
New gold-and-silver alloy terminals for lowest transfer resistance anddurability are directly connected to the crossover circuit board to ensurecomplete current delivery and no loss of clarity in the signal transfer frombinding post to crossover.
Cabinets boast massive baffles that are 1.25" thick, 25?hicker thanprevious models, for maximum rigidity and resonance control.
Maple and Cherry finishes join a revised Rosewood, applied to the highestof standards using the state-of-the-art veneer-wrapping technology forthe front and rear baffles first pioneered on the Classic series. A true PianoBlack lacquer is now available, the quality of which will permit inclusioninto any living room as it mirrors its surroundings.
Innovative and unique grilles feature an aluminum frame that incorporatesan integral V-shaped phase diffuser to control dispersion so that they canbe left on for all but the most critical listening without an adverse influenceon performance. In fact, it can be used as an additional tuning device forthe audio enthusiast, benefiting soundstage presentation both in depthand stereo imaging. As an additional benefit, the V-shaped groove runningthe length of the middle of the grille results in a more elegant appearancefor the speaker.
The pressure within the cabinet is inconceivably high. Besides the massivethickness of the tube, the only way solid enough is to screw the port tubesto the cabinet. Furthermore, the exact length of the ports determinesthe right and only frequency „fb" of the port-cabinet-driver system; thistuning is a matter of millimeters. The dual front bass-reflex ports increaseMAESTRO Grand´s dynamic capabilities and are used with two differentlengths.
