Product Details

【Product Description】
Size: 75mm square / Height 47mm
These audio insulators and bases are crafted from carefully selected stainless steel.
Unlike commercially available lightweight insulators, these are formed with cutting-edge technology into a solid block weighing over 1kg.

【4 Features of This Product】
1. Ultra-Heavyweight 1000g Fixed: Filled with iron sand internally. An iron core is also welded and fixed inside. All three units are adjusted to within ±1g (excluding rubber parts). This overwhelming mass and combination of materials physically subdue the intense vibrations of large woofers and speakers.

2. Complete Sealing of SUS304 × Iron Sand: Iron sand is sealed within a thick, rust-resistant SUS304 case and hermetically sealed with TIG welding. There is no worry of sand leakage or oxidation over time.

3. #600 Buff Finish by Hand: Meticulously buffed from the base preparation, each piece is finished by hand. It boasts a deep, sharp shine that will enhance any interior.

4. EPDM 3-Point Support (Underside): 2mm thick EPDM rubber, known for its weather and vibration resistance, is pre-attached in 1cm square pieces at three points on the bottom. You can use them immediately for ideal setup upon arrival.
*The top surface is intentionally left bare to accommodate users' various preferences.
In the unlikely event of wobbling, six pieces of the same rubber used on the bottom will be included.

【Specifications】
• Material: Main body SUS304 Stainless Steel / Internal Iron Core & Iron Sand
• Weight: 1000g (per unit) × Set of 3
• Finish: #600 Buff Finish
• Underside: EPDM Rubber (2mm thick) 1cm square, 3-point support specification

【Notes】
• As these are handmade items, there may be minor buffing marks or individual differences in dimensions from the manufacturing process. Please purchase only if you understand and appreciate the craftsmanship of these handmade products.
• These are heavy items weighing over 1kg each. Please exercise extreme caution during installation and handling.

【PR】
We understand that the audio community is filled with individuals who have diverse opinions and theories.
We also accept custom orders for size changes (up to 120mm square, heavy-duty models), changes in internal materials (e.g., zircon sand), and processing for spike receivers in the center.

We would be delighted to help you bring your ideal setup to life.

Please feel free to consult us in the comment section if you have any requests.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
