前回のブログで取り上げたJBL 4312が組みあがりました。音質の評価が終わり次第、周波数特性の測定を行います。
The JBL 4312s that I posted in my last blog has been completed. After the sound quality check, I will take it's frequency characteristic data.
こちらは4350A用に使用する背面端子プレートを作製している様子です。シングルアンプ接続が可能なネットワーク設計になっています。これから仮配線で組み上げたネットワークのテストを行いますので、最終的な回路が決定次第、配線を開始します。
This is the rear binding post panel for the JBL 4350As. The crossovers are designed so it can been driven by a single amp. After the crossover tests are over and the final schematics are decided, I will start to wire them.
