我們正在生產自業務開始以來最受歡迎的型號的 10 週年限量版，LS5/9、LS6 和 LS3/5a 三種型號每個型號限量 100 對。
所有型號均由 Derek Hughes 進行了升級，同時仍符合 BBC 標準（LS6 除外）。
升級包括 WBT – 730.01 終端、Van Den Hul 佈線以及帶有升級組件的重新設計分頻器。
箱體將全部採用桉木材質，並帶有黑色擋板，我們將僅在這個特別版本中使用這種飾面。
對於所有 3 個型號，較高密度前擋板的剛度增加，可減少驅動單元產生的振動傳遞到機櫃的其餘部分，並降低機櫃壁的共振，使內部面板阻尼更佳有效的。最大限度地減少箱體共振使揚聲器能夠更好地恢復低電平音樂訊息。
現在，除了 LS3/5a 位於後面板上之外，所有型號的前面板上都將配備高頻開關。這樣可以將機櫃微調到適當的房間。
所有產品均附有認證證書，並以客製化的十週年紀念紙盒交付。
LS5/9週年紀念版：
- 升級後的 SB 高音揚聲器，範圍高達 20khz。
- 與升級的聚丙烯電容器和金屬外殼電阻分頻，以提高熱性能。
- 升級的 Van Den Hul 佈線。
- WBT 終端。
- 桉木單板採用更新的擋板設計、新的更高效的端口佈置和黑色擋板。
- 前面板開關取代焊腳Trafolyte板，開關更方便。
- 認證證書
- 訂製紙箱。
- 改進的球頂高音揚聲器提供了更好的離軸響應，以及更平滑和更擴展的高頻響應。
- 高音揚聲器組件直徑的減小也意味著聲學中心更靠近低音驅動器，從而更好地整合響應。

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.
