  1. ※Please confirm whether it is animal fur. Animal fur products are in conflict with the Washington Treaty and cannot be shipped internationally.
スタジオ使用のH社メンテ返り品ですが出番があまり無いので出品致します。

一つ気になるのがマジックでユニットに目印がついております。

ちゃんと規定値通り出ており、音出し良好で傷も少なめです。
紙もオリジナルのままでエッジと共にまだまだそのままお使い頂けます。


二個口発送となりますが佐川急便では一つ口で発送出来ます。

46cmウーファーでしか出せない、太さのあるサウンが魅力です。デジタル録音に対応した重低音再生に有利な大口径ユニットを是非お試しください。



強大な出力音圧を低歪率で実現する「スーパー・ヴェンテッド・ギャップ(Super Vented Gap)」技術を搭載した低域用トランスデューサです。
定評あるヴェンテッド・ギャップ・クーリング技術とシンメトリカル・フィールド・ジオメトリ構成を 進化させ、放熱と磁気回路性能が向上しています。

感度が増加しパワー・コンプレッション(実効感度の低下)が減少したため、実効出力が増大しました。
歪率 はさらに減少し、トランジェント特性も改善しています。映画用サブウーファなどに最適です。

排出容積9lit
重量13.2kg

技術/設計上の特徴
Super Vented Gap(SVG)クーリング技術
ボイスコイル周辺と磁気ギャップを通じて空気を流動させ、熱を効率的に排出する設計。これにより長時間の高出力運用でも熱による性能劣化(パワー・コンプレッション)が抑えられています。

Symmetrical Field Geometry(対称磁場構造)
ボイスコイルを磁気回路内で対称なギャップ構造の中に配置することで、磁束の非対称性を低減し、歪みを抑える設計。特に振動の極性や運動の上下負荷が一定になるようにしているとのことです。

低歪/優れたトランジェント特性
高調波歪(第2、第3高調波)を 1% 以下に抑えるスペックを持ち、かつコーンの動きの制御がよく、応答性(立ち上がり/立ち下がり)が良い。これもミュージカル/映画用途などで重視されるポイントです。

高い出力音圧
1 m 離れて 100 Hz 以上で 134 dB のピーク出力が可能というデータがあります。非常に大きな音圧を要求される用途、例えば映画館サブウーファーなどにも対応できる性能です。

fs(自由空間におけるドライバの共振周波数)35Hz
Qts(全ての損失メカニズムを含んだfsにおけるドライバQの総計)0.28

Qms(機械的損失のみを含んだfsにおけるドライバのQ)5.0

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.
