丹麥喇叭名廠DALI於2017年5月德國慕尼黑音響展時發表旗下嵌入式喇叭系列,並且以「Phantom」(魅影)系列命名,來彰顯其可以完全融入居家環境、環繞包圍發聲無影無蹤的過人性能。當時DLAI所推出的有家族旗艦款Phantom S系列(詳見這裡)與較平價的Phantom H系列,之後又推出更小巧、入門款的Phantom E系列(後兩者的深入剖析請見這裡);不過,倘若仔細比較的話,就會發現頂級Phantom S與中階Phantom H之間的落差其實不小,尤其是在音箱容積與單體數量部分,於是DALI日前就推出了介於兩者之間的Phantom M新系列,既有接近Phantom S-280較長比例的漂亮外觀、又有與Phantom S-180相近的前面板長度與更窄的寬度,更適用於大多數居家場合且能帶來與頂級Phantom S系列接近的性能。

DALI Phantom M系列目前有Phantom M-250(左)與Phantom M-375等兩款製品,兩者音箱尺寸完全相同,都是長775mm、寬250mm、深106mm,但單體配置與低頻延伸設計卻不相同,這也使得兩者主要性能量測數據雖大致接近但音色仍有差異,可讓消費者依個人偏好挑選。Phantom M-250與Phantom M-375的發聲率都是89dB(2.83V/1m)、一般阻抗皆為6歐姆、最大音壓都是107dB,只在頻率響應規格有58Hz-24kHz±3dB(Phantom M-250)與57Hz-25kHz±3dB(Phantom M-375)的微小差別;不過,中低音部分Phantom M-250搭載兩支5.25吋單體並採用低音反射式音箱,而Phantom M-375則以一支7吋中低音單體搭配兩支7吋被動輻射器,這就使得兩者的中頻與低頻速度有些不同。

在高音部分,Phantom M-250使用一支28mm直徑軟振膜單體,而Phantom M-375則搭載DALI獨家且著名的雙高音模組——在28mm軟振膜高音之外還加了一支17mm×45mm鋁帶超高音,這是延續自Phantom S系列與DALI高階Epicon、Rubicon及Opticon等系列製品的獨特技術。此外,DALI這兩款Phantom M系列嵌入式喇叭在高音單體旁都設有一個「HF+」按鍵(上圖紅色箭頭所指處),當用家將Phantom M系列嵌入式喇叭安裝於透聲銀幕後方時,就可按下此鍵適度增強高頻量感,以補償喇叭聲波穿過透聲銀幕時之高頻量感衰減。

儘管DALI為旗下各款喇叭都特製專用單體,但由於兩款喇叭所配備的高音及中低音單體不同,分頻網路設計自然有差別,Phantom M-250的軟振膜高音與5.25吋中低音單體分頻點設於2,720Hz,Phantom M-375則是在2,500Hz處、而17mm×45mm鋁帶超高音則增強15kHz以上的極高頻延伸。

雖然振膜尺寸有5.25吋與7吋的差異,但Phantom M-250與Phantom M-375的中低音單體結構大致相同,也都如同其他DALI中低音單體一樣使用木質纖維與紙漿混合製成的振膜,看到振膜表面那些細細的條狀物可別以為DALI作工不細緻,其實那就是振膜裡的木質纖維,此種振膜的厚度非常非常薄、質量非常非常輕,但剛性又十分強韌、不易變形,DALI喇叭能有極佳的中低頻速度及解析,此特殊振膜是十分關鍵的獨家技術。

此外,Phantom M系列這兩款喇叭的中低音單體,也承繼了過去用在DALI最高階Epicon、Rubicon與Opticon等三個系列以及Obern系列與Phantom S系列的SMC技術。所謂SMC是Soft Magnetic Compoun軟磁複合材料的縮寫,由DALI自行研發而成,具備高導磁率、低導電率(僅為鐵的萬分之一)特性,可大幅降低磁滯現象。有關DALI複合式高音模組及中低音SMC技術的特點剖析,可點擊查閱本站先前對於Opticon系列的深入剖析報導。

Dali M350-6Phantom M系列的音箱深度只有10.6公分,在側面左右兩側各有三個可彈出之橘紅色卡筍,安裝時先在牆面或天花板挖出長751mm、寬226mm的方孔,將Phantom M系列喇叭塞入後,就可利用前面板螺絲將卡筍彈開並鎖固,讓安裝好的Phantom M系列喇叭與牆面或天花板融為一體。

即使不加上網罩,Phantom M-250或Phantom M-375嵌入式喇叭也能與各種材質、色彩的牆面不突兀地融合在一起。當然,如果加上網罩並對其做仿牆面色彩之處理,就讓人更不容易察覺其存在了。

DALI Phantom系列喇叭都是與牆面或天花板完全嵌合的,這樣不會影響立體聲播放的包圍感及音場表現嗎?不用擔心,所有DALI喇叭都有極寬廣的擴散角,原廠也都建議不需要向內Toe-In,看看上面這張DALI所公布Phantom系列的聲波擴散範圍示意圖,可以發現左右兩支喇叭聲波擴散範圍極廣,兩者所交會的扇形區域(上圖中央較淺綠色處)涵蓋了整個空間面積一半以上,也完全包含一般主要視聽區域。

Phantom M系列兩款製品的主要規格列表,它們的頻率響應、發聲效率、一般阻抗、單體尺寸、數量及音箱形式尺寸等數據前文已有說明,在此補充Phantom M系列的最大音壓皆可達107dB、建議擴大機由30瓦至180瓦,相當容易驅動。
