英国Castle(城堡) Richmond Aniversary 列治文周年纪念版书架音箱

Anniversary周年纪念版为二路二单元低音反射式设计，采用19mm高音单元一只，110mm碳纤维编织振膜中低音单元一只。针对Anniversary周年纪念版，Castle的工程师研究了Richmond性能的各个方面，以提炼出这对小型监听音箱的最好音质。采用的震动和光谱分析来调查研究箱体的情况，Richmond 3i在原先的15mm MDF箱体基础上加入沥青阻尼物以避免不必要的谐振与不良的音染；而在Anniversary周年纪念版中，Castle的工程师利用多层复合面板材料及松散纤维编织结构吸收内部声波，把面板共振降到了可听度以下，还加入了支撑架，以确保驱动单元的动态能力完全实现。Castle著名的碳纤维编织振膜保留了下来，因为它在质量比方面表现出色。采用Kapton线圈架配以包铜铝音圈，目的是实现更广的频宽。这个110mm的单元安装在Castle经典的铸造合金底盘上，频宽出众，动态性能一流。高音是19mm的聚胺微纤维半球，它直径小，可将高频扩展至可听度限值以外。分频器虽简单，但经过彻底研究，能够在很广的聆听角度下实现一流的线性。挑选分频器零件时考虑到声音的透明度，包括铝铁迭片低音电感、超大空心电感、Castle专有的聚丙烯低损耗电容。将高音单元置于低音单元之下为单元之间提供了时间校准度。Castle所有音箱都用美观的原木薄板饰面，并由人工根据箱体尺寸细心挑选，且每对箱体都是以“成对匹配”的形式生产，包括木皮上的木纹。Castle挑选了极佳纹路切割的薄板饰面，以确保Richmond Anniversary周年纪念版让用家的眼睛和耳朵都有美好的享受。

The Richmond Anniversary is Castle’s smallest and first loudspeaker to redefine studio monitor sound and furniture quality craftsmanship. It offers exceptionally natural reproduction of musical instruments and voices across all musical genres. Its enhanced dynamics and transient capability bring musical richness and excitement that will have you exploring your entire music collection.

Castle engineers succeed in reducing panel resonance to below audibility by using multi-layer, composite panel materials, a loose fibre weave and bitumen damping pads to absorb internal sound waves. Additional internal bracing ensures that the dynamic capabilities of the drive units are fully realized. Special attention is also paid to the construction of the grille cover. The frame is composed of two different wood materials for added rigidity thereby minimising any form of resonance.

The new Richmond Anniversary employs a 130mm carbon fibre woven bass unit and a polyamide micro-fibre 19mm dome tweeter. The bass driver operates as a pure piston over its pass band and offers a remarkable bandwidth and superb dynamic performance. The tweeter has exceptionally wide bandwidth, with the upper limit of high frequencies extended to well beyond audibility. The use of a simple but thoroughly researched crossover network with Linkwitz-Riley slopes achieves superb linearity over a wide listening angle. Crossover components have core bass inductors, generously oversized air core inductors and Castle’s proprietary, low-loss polypropylene capacitors.

Input to the crossover and drive units is via updated bi-wire terminals which accept bare wires, spade lugs, pins or 4mm plugs allowing your preference of speaker cable connection. Together with the crossover PCB layout, the bi-wire terminals allow full star grounding back to the amplifier for minimal crosstalk between the split frequency sections.

Beautifully veneered in real lacewood, specially chosen by highly experienced Castle cabinet craftsmen, some of whom have specialized in selecting the right veneer for each application for more than 30 years, the new Richmond Anniversary will complement conventional to modern room environments.
