A5 三路五單元座地揚聲器
評測報告:
美國 魔力Magico 繼2020年初先後發表AAC中置和ASUB有源超低音之後,決定加推一款能切合較大聆聽環境,份屬A系列旗艦一哥的A5。儘管它的造型、高度和闊度跟名振天下A3極為相近,個中分別只是A5的深度略為增加4吋,而每隻體重則暴增超過60% 水平!導致重量遞增的其中一個原因,正是由多件表面經過拉絲及黑色陽極處理,質量跟經典Q系列相同的 6061-T6 航天級鋁合金板件組合而成的密封式聲箱,內裡除加入強化支架,高音和中音單元更享有完全獨立密封式房間,防止干擾的產生。
耳熟能詳 28mm半球型鈹高音
貴為該社A系列的大當家,掌門人兼設計師 Alon Wolf 先生對於單元的取決顯然非常執著,且看開發概念沿自百萬元級 M系列,輕易直達 50kHz 領域的秘製半球型高音,其28mm振膜選用具備上佳散熱效能的鈹金屬生產,結構特殊的釹磁鐵迴路,亦加入嶄新阻尼物料,全面切合高音壓與低失真再生的嚴格要求。
嶄新5吋三文治中音搭載泡沫素材懸掛
A5將會配備全新研發,既可締造更遼闊聲音擴散,透明度亦提升至另一層面的5吋中音單元。運用特殊手法加工成形的三文治錐形振盆,其生產物料同屬抗拉強度遠高於碳鋼50倍的 納米石墨烯 Graphene Nano-Tec,至於度身訂製的懸掛部份則改用泡沫素材生產,有助提升運作反應和降低失真,讓振盆和懸掛達至更為理想化的局面。音圈嚴選鈦線材繞製而成,配合超穩定的磁場和純銅製極帽,減少渦流的產生,將工作效率提升至最高水平。
三枚9吋口徑低音採用5吋鈦音圈
跟先前提及的中音單元一樣,A5所使用的三枚9吋口徑低音,全屬廠方加料炮製的自家作品。揉合石墨烯、碳纖維和十分輕巧全新夾層物料的三文治錐形振盆,全面實踐高剛性 / 重量比。借助電腦進行設計的單元支架,有效抵消工作時所引發的共振影響,同時容許更大的氣流通過,加強散熱效能。5吋直徑鈦音圈配合龐大穩定的磁場,縱使輸出音壓處於極高水平(115 dB!),仍可保持極低失真和電感 (0.18 mH),全賴Finite Element Analysis (FEA) 測量軟件的協助,為Magico工程團隊提供一個聲學、機械、電磁和熱性能的評估平台,方可炮製出如斯精湛的單元。
全球首對選用 Mundorf M-Resist Ultra電阻器的發燒揚聲器
A5所採用的三路五單元被動分音系統,屬於4階 Linkwitz-Riley -24dB 衰減方式規劃,用意締造準繩精確的銜接和遼闊頻應。構成這套分音器的零件,除了德國發燒補品製造商 Mundorf 受注生產,零售價格十分可觀的電容器,還有可承受大功率,透明度與動態出眾M-Resist Ultra大功率薄膜電阻器。據廠方表示,A5將會是全球首對選用 Mundorf M-Resist Ultra大功率薄膜電阻器的發燒揚聲器,意味著它的音效表現必屬非同凡響。跟其它 美國 魔力 Magico 產品一樣,每對A5 均在美國加州的廠房內生產和測試,確保產品質量。
