BOSE 101MM 1ペア(シリアル連番)

【商品説明】

BOSE 101MMは1982年から2001年頃にかけて製造された製品です。
最終生産品であっても25年、初期モデルでは40年以上が経過しています。

内部のEQ基板(音質を補正する回路)に使われている電解コンデンサは消耗品であり、設計上の標準的な寿命は15年〜20年程度です。長期間の経過により内部の液体が蒸発する「ドライアップ」が進行すると、寿命を迎えたコンデンサは内部抵抗(ESR)が増大し、本来の信号伝達を妨げる要因となります。

これが「音がこもる」「低音のキレがなくなる」といった音質の劣化を招きます。

パーツ寿命による劣化を解消して本来の性能に戻すため、本出品個体には以下の処置を施しています。

【メンテナンス内容】

- 電解コンデンサ新品交換
(オリジナルと同等の容量・耐圧を持つ、現行の新品バイポーラコンデンサを使用)
- 各部クリーニング・接点清掃
- DCR(直流抵抗値)3.4Ω /  3.4Ω
(※101MMの公称インピーダンス6Ωに対し、適正なDCR値です。左右のバランスも非常に良好です。)

【FQA】

Q. シリアル連番だと何が良いのですか?
A. 製造時期や使用環境が同一である可能性が高く、左右の特性(音の傾向)が揃っており、ステレオ再生時の定位感が安定します。

Q. 101MMの内部設計とメンテナンスの必要性
A. 101MMのスピーカーユニットは単体で約1.6〜2.0Ωという極めて低いインピーダンスとなっており、内部基板(コイル・抵抗・ランプ・コンデンサ)を通すことでシステム全体として「6Ω」へ整合させる特殊な設計がなされています。
コンデンサの寿命による特性変化は、これら複数の素子で構成された回路全体のバランスを崩す直結的な要因となります。そのため、経年劣化したコンデンサの交換は、本来の設計意図を維持するために必要なメンテナンスとなります。

Q. DCR(直流抵抗値)を計測する意味は?
A. ユニットの健康状態を客観的に確認するためです。
「インピーダンス」が音楽再生中の動的な抵抗値であるのに対し、「DCR」は静的な抵抗値です。スピーカーの公称インピーダンス(本機は6Ω)よりも低い数値が出るのが正常であり、左右の数値が近いことは、ボイスコイルの個体差や劣化が少ないことの証明になります。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.

※ Note: Photos provided to sellers should not contain any foreign-related information.
