毎年年末にPASS LABORATORIES Rushmoreに蜜ろうをかけている。これもう恒例行事と言ってもよい。これで我が家のメインシステムの年納めができる。昨年も行っていたが、 Blogにアップしたのは今年になってから
2025年は過去10年で一番Rushmoreの（というかメインシステムの）稼働時間が短かったかもしれない。オーディオルーム Audio barn にこもっていた時間は逆に最大レベルだったから、サブシステムのACOUSTIC ENERGY AE2 Signatutreに極端に寄ったということだ。Rushmore : AE2 Signature = 1 : 99 くらいだった気がする。
思いつく理由は色々あって、まずは子ども達の学業上、大きな音が出しにくくなったこと。Rushmoreは軽量コーンの高能率アクティブスピーカーだから（色付けのある）微小音再生には優れているが、それでもある一定以上の音量の方が映える。聴きがいがある。
もう一つはドルビーアトモス（Dolby Atmos）に入れ込んだこと。これはDENON AVR-3800Hを中核とするサブでしかできない。Dolby Atmosは非常に面白いと思ったし、来年も続けたい。
さらに、映画でもサブスクでもYouTubeでも、映像を見るにはサブでないといけないので、こちらの比重が高くなった。ソフトの点では、以前はメインでしか聴けなかったレコードもサブでも聴ける様にしたから、音源の偏りもなくなった。
最後の理由はやはり両親の介護か。どうにも一人ゆったり音楽を、という気分にならぬ。年中 気が重い。
上記いくつかのことは来年解決するだろう。そしてまた別な事態が待ち受けるに違いない。人生そういうものだ。
冒頭の蜜ろうがけに戻る。
そんな状況なので Rushmoreサイドの突き板は昨年から綺麗なままだったが、それでも油分水分は飛ぶだろう。念入りに擦り込んだ。
今年は Rushmore 19年目になる。ここまで長く付き合えるとは思っていなかったし、無故障でここまできただけでも立派だぞ、Rushmore。
Every year at the end of December, I apply beeswax to my PASS LABORATORIES Rushmore. By now, it’s fair to call this an annual ritual. It marks the year-end closure of my home’s main audio system. I did the same thing last year as well, although it seems I didn’t post about it on my blog until this year.
In 2025, the Rushmore—indeed, my main system as a whole—may have seen the shortest operating time of the past decade. Ironically, I probably spent more time than ever holed up in my audio room, “Audio Barn,” which means my listening shifted overwhelmingly toward the sub-system built around the ACOUSTIC ENERGY AE2 Signature. If I had to put it into numbers, the ratio of Rushmore to AE2 Signature use felt like something close to 1:99.
There are several reasons that come to mind. First, due to my children’s academic commitments, it has become difficult to play music at high volume. The Rushmore is a high-efficiency active speaker with lightweight cones, and it excels at low-level reproduction—even with a certain degree of tonal coloration—but it truly shines at volumes above a certain threshold. That’s where it becomes deeply engaging and rewarding to listen to.
Another reason is that I became deeply absorbed in Dolby Atmos. This is something I can only do on the sub-system, centered around the DENON AVR-3800H. I found Dolby Atmos to be extremely fascinating, and I plan to continue exploring it next year.
In addition, whether it’s movies, streaming services, or YouTube, watching video content inevitably means using the sub-system, which naturally increased its share of use. On the software side, I also made it possible to play records on the sub-system—records that previously could only be enjoyed on the main system—so the imbalance in source material has essentially disappeared.
My audio room, the “Audio Barn,” is a semi-basement space facing north, with a single window that remains permanently covered by curtains. Even so, I normally keep the front panels covered—both to prevent the Rushmore’s speaker units from sun damage and to protect them from any unforeseen accidents. Fully wrapping the entire speaker would be more trouble than it’s worth, and more importantly, it would likely discourage me from listening to it at all.
Under these conditions, the veneer on the Rushmore’s sides has remained pristine since last year. Still, oils and moisture inevitably dissipate over time, so I worked the beeswax in thoroughly and with care.
This year will mark the Rushmore’s nineteenth year with me. I never imagined we would be together for this long, and the fact that it has made it this far without a single failure is impressive in itself. Well done, Rushmore.
