GRAHAM AUDIOLS5/8S 揚聲器

LS5/8S

與原始 LS5/8 版本相比，我們對 LS5/8S 設計做了兩項重大變更。

首先是在低音驅動器前方使用繞射槽。

最初的 BBC 研究部門 LS5/8 設計確實有一個插槽，但在最終生產版本中被刪除了。

我們生產的 LS5/5 帶有插槽，這對於提高離軸響應的平滑度非常有效，因此我們將其融入 LS5/8S 中，並獲得了明顯的聽覺改善。

與攝影棚控制室中經過聲學處理的空間相比，在通常更具「現場」聲學效果的家庭客廳中，改善更為明顯。

第二個變化是用 Seas 34 毫米高音單元取代了 Audax。 Seas 機組曾用於我們的旗艦 VOTU 和專業錄音室揚聲器，它的性能得到了提升，尤其是在分頻點上方區域，與改進後的低音單元配置帶來的更平滑的響應完美融合。

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.
