ローパスフィルターの無い サブウーファー用です。

発送は写真の通り、1個のみです。

本品の配線は16ゲージのスピーカー線が使用されており、合計の長さは約25cmです。

以前 欧州車にお乗りの方からのお問合せで、フロア?シート下? にあるサブウーファーはフルレンジで鳴っていて、みんカラの記事を参考に ローパスフィルターにて音質改善を測りたいとのことでした。

ドアスピーカーのミッドウーファーではなく、「サブウーファー用」にして、これまで当方が取り扱った「最重量級」の空芯コイルになります。

引き合いに BEWITHさんの L-165R用ローパスフィルター「X-WR3」があげられますが、あちらは形状からして 空芯コイルではなく、おそらく磁芯か鉄芯と思われます。

こちらの純銅空芯コイルの方が 磁気飽和やコアによる損失が起こりにくく Hi-Fiで オーディオ向きです。

また、BEWITHさんの L-165R用ローパスフィルター「X-WR3」はミッドウーファー用と思われますが、カットオフ周波数を公表しておらず 流用した場合 音の変化は感じられるものの 用途としては正しいと言えません。

20cm程度(8インチ)のサブウーファーで 且つフロアかシート下に設置した場合 指向性が問題になる周波数は 約860Hz付近です。完全に指向性が無くなるのは更にその半分の430Hzとなると、一時タイプのローパスフィルターで 1オクターブ下の215Hz以下にするのがベストかもしれません。
※装着する車両のシステムによる為、あくまでも一例です。

■配線方法
アンプとサブウーファーが繋がるスピーカー線の+か-側を切断して、本品のケーブルを割り込ませて接続します。
必ず 結線箇所は市販の絶縁ビニールテープ等にて処理して下さい。
必要であれば 配線を延長してご使用下さい。音質確保の為 同じく16ゲージ以上のスピーカーケーブルをご使用下さい。

■お願い
自作品の為、神経質の方はご遠慮下さい。
ツイーターに繋がる配線には接続しないで下さい。
水にかかったり 湿気の多い場所には設置しないで下さい。

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.
