KT88-SE & JBL4344 真空管アンプで聴く38センチウーハーのJBL

JBL 38センチウーハーの4WAYホーンスピーカーはSEASやSCANSPEAKのLR4-2WAYとはまた少し違う音です
4312SXは 30センチ なんですが あまり 設置環境を選びません　ですが 38センチ になると とたんに難しくなります
38センチは 部屋全体を ドライブするカンジが強く 狭い空間では そのメリットを 享受できるとは思えません
広い空間で 伸び伸びと鳴る 4344の音を 聴いたことがある方には その意味をご理解いただけると思うのです　
JBL4344は 田舎の進学校を優秀な成績で卒業し 都会の一流企業に就職し 満員電車に乗って 35年ローンを組んだ ウサギ小屋でアクセク働く そんなエリート 労働者 には 全く理解できないであろう 階級社会が残っている 異国の文化の製品です
日本向け専用品なのにねｗｗ

Those are some serious speakers

4-way speakers ? I like the sound even if "it is slightly different from SEAS 2-way" BUT I can't accommodate speakers so big (for this reason I'm seeking around for the ISIDA BHBS ) . Have you any "open baffle" speakers to compare (as I can see, you have plenty of space that permits the "expansion" to the lower notes )

[@seaslyd]

Open baffle type speakers must lower the frequency at which cancellation occurs as much as possible. Specifically, they must use as large a plate as possible. This is what I know, but I wonder how to best achieve this in the real world.

@@seaslyd about 7,5m for 23Hz (half wave) and then again using sound absorption panels. Not a viable solution for a live house . In my living room the lowest frequency is about 80Hz at LOW LEVEL (BEFORE the ceiling starts reflecting). Not a chance for installing sound absorbers due to WAF

[@seaslyd]

@@gamiwv I also have a hard time with WAF. This state of the room is faked only for the video. It is impossible to occupy such a space for sound in a normal home.
