長岡鉄男氏設計 BS-8 フォステクス P800k アンティーク仕上げ2台1組

BS-8は、長岡鉄男氏の最初期に発表されたエンクロージャーで、昭和51年発行の「続・オーディオ日曜大工」音楽之友社に「超小型バスレフシステム」として掲載されていました。「床にころがしておくのが最高。だまって聴かせると、8cm1本と思う人はひとりもいない」とは、氏の解説。しかし、関心は同誌のFE-203二発入りのバックロードホーンで、製作してその迫力に感動して、オーディオ沼にはまることになりました。時は流れ、最近になって、これまで関心の無かった小型スピーカーを作りたくなり、今回は氏の出発点とも言えるBS-8を製作した次第です。
本來、搭載ユニットは、フォステクス(当時はフォスター)の8cmフルレンジFE83でしたが、本機は
P800Kを使用しています。
箱は、15mm厚シナランバーコア材で、(底面は18mm厚)木ネジ、木工ボンド併用。仕上げは、ウォールナット水性ステイン塗布後ターナー社ミルクペイントのスノーホワイトを塗り、同社アンティークメディウムで汚しをつけ、アンティーク塗裝してみました。ですから、商品状態はやや傷や汚れありとしました。ユニットの取り付けは、M3サイズ爪付きナットを埋め込みましたので、板割れの心配なくガッチリ搭載できます。またボルトにも錆風塗裝をして、ノスタルジックな雰囲気を演出してみました(写真6.7.8)

幅:130 奧行:155 高さ:178
約mm 重さ:約1.0kg

音出し比較は(写真10)
①兄貴分のフォステクス FE103En
メーカー推奨バスレフ箱の円形ダクトをスリットダクトに変更した箱。
10cmの103は能率が高く、セレクターで本機に切り替えると、
ぐっと音量が下がりますが、VRを上げれば俄然元気に音が飛び出してきます。が情報量で103がやはり有利か。
②本機と同じP800kで、こちらはダブルバスレフ。若干低域でダブルバスレフ有利と感じましたが、ほとんど差は認められず、このサイズで元気に鳴りまくる本機に軍配。
(あくまで、私感です)
※口徑8cmのユニットゆえ、ガンガン鳴らすスピーカーではありません。

素人の自作品です。工作精度の未熟さ、製作過程での傷、塗裝ムラなどありますことにご理解、ご承知の上、写真にてご判斷下さい。コーン紙を保護してプチプチで包み手持ちの段ボール箱にて発送予定です。
