Welcome to inquire if you have any product questions.

LS5/5f 具有與 LS5/5 相同的驅動器組件和箱體,但作為改進的(在低音區域)分頻器和下方額外的 16 英寸外殼。驅動器和分頻箱下方的第二個箱體是一個聲學室,可讓低音驅動器呼吸。這種帶有端口的外殼提供了增強的低音擴展和動態能力。雖然落地式版本與直立式版本具有相似的中頻,但在 20Hz 下測量時,它的低音多出 7dB。

最初設計於 1967 年,BBC 對 LS5/5 的設計感到非常自豪,BBC 的許多人認為它是他們設計的最好的揚聲器,他們用它來監聽古典音樂的錄音。快轉到 2019 年,使用更高品質的磁鐵、驅動器、膠水、分頻元件;改進後的 LS5/5 現在的功率處理/輸出提高了 10dB。這比原來的聲音大八倍。正如您從白皮書(點擊此處)中看到的,最初的 LS5/5 由板載 25 WPC 擴大機供電。 2019年款格雷厄姆將LS5/5修改為被動設計。

然而,當搖滾時代到來時,工程師發現LS5/5播放聲音不夠大,所以他們推出了LS5/8。 我們的消息人士透露,BBC 幾十年來一直使用這些揚聲器進行麥克風校準,以確保麥克風符合 BBC 的技術規格。當您考慮到 BBC 可以訪問當今市場上的幾乎所有內容時,這就是對原始 LS5/5 設計的巨大讚揚。

GRAHAM AUDIO - UK

Graham Audio is a British family-owned company headquartered in Newton Abbot, a small market town in Devon, southwest England. We are passionate about high-quality audio and believe that classic BBC loudspeaker design offers a neutrality, transparency, and authenticity that is hard to find elsewhere today. Using modern components and production techniques, we are able to maximize performance while maintaining the original design. All loudspeakers are hand-assembled on-site. One person oversees every step of the production process, including testing and auditioning. A second person carefully inspects the finished product, repeating the tests as a matter of course and saving the results for future reference. As part of the testing procedure, all completed loudspeakers are compared to our master reference samples to ensure complete consistency. Graham Audio is proud to work with some of the best minds in the industry, including Derek Hughes and Volt Loudspeakers. Our loudspeaker systems are available from carefully selected dealers worldwide, who have full demonstration facilities and will support you through the selection and setup process.
