Extensive product selection and technical variety
These 12" recone kits are especially suitable for users who want to quickly restore their defective 30 cm subwoofer. Our brand manufacturers and models vary in several technical parameters:
- Power range (RMS): 800 W to 3,000 W
- Impedance: 1×2 Ohm, 2×2 Ohm, or 2×4 Ohm
- Voice coil diameter: 2.5" (63 mm), 3" (76 mm), or 4" (102 mm)
- Cone materials: pressed paper, composite materials, or carbon fiber
- Voice coil former material: aluminum or Kapton for maximum temperature resistance
The included components allow for a precise fit and reliable signal transmission. This makes it possible to revive even high-quality competition subwoofers from Deaf Bonce or B2 Audio and bring them to the desired sound level. With the supplied adhesives, sealing rings, and centering spiders, a harmonious adjustment between the voice coil, diaphragm, and suspension is achieved, ensuring the sound remains stable even at high volumes.

Professional installation: tips and accessories
To ensure smooth installation of the new 12" recone kit, the extensive accessories offer numerous advantages. In addition to adhesives and centering aids, a special paper surround protector is usually included, which securely fixes the moving parts. The following step-by-step recommendations support the assembly:
- Clean old cone, dust cap, and surround and completely remove adhesive residues
- Accurately center the new voice coil before embedding the cone
- Glue the dust cap flush with the cone and let it cure overnight
- Secure cable connections including strands with heat shrink tubing against moisture
- Strictly dose recommended adhesives according to manufacturer instructions
Additionally, if needed, accessories such as ring terminals, adapter plugs, and rubber gaskets can be retrofitted if the existing subwoofer enclosure has special dimensions. If you're unsure whether the chosen recone kit is immediately compatible, you can consult the AI chatbot at Masori (see https://masori.de/pages/faq-und-hilfe) or contact expert support directly.

Brands in Focus: B2 Audio and Deaf Bonce
B2 Audio has focused for years on high-performance car audio solutions and offers various 12-inch recone kits specially matched to their high-end subwoofers. Typical values range from 1,500 W to 3,000 W RMS power, enabling powerful deep bass attacks. The used 3" or 4" voice coils usually operate in 2×1 Ohm or 2×2 Ohm configurations, allowing various amplifier setups. The cone blanks (pressed paper or carbon fiber) are highly stable and suitable for powerful applications in competition vehicles.
Deaf Bonce is known for massive bass performance and develops recone kits for heavy-duty everyday use or sound-off events. The spare parts feature precise centering spiders and multi-layer voice coils up to 65 mm high to ensure high power handling. Those who value extreme volume combined with accurate frequency response benefit from Deaf Bonce recone kits with 2.5" to 3" coils and RMS ratings (e.g., 2,000 W). Thanks to the plug & play design, many Deaf Bonce kits can be integrated into SUVs, vans, or compact cars without extensive modifications.
Optimal integration in vehicles from Audi to Opel
The 12" recone kits from the Masori online shop are excellent for breathing new life into the car audio system in sedans, coupes, or station wagons. These include, for example:
-
Audi drivers looking for crisp deep bass in the A3 or A4
-
VW enthusiasts who want to upgrade the Golf or Passat with powerful kick bass
-
BMW fans who desire precise low-frequency reproduction in the 3 Series or 5 Series
-
Mercedes vehicle owners who want to enhance their C-Class or E-Class with a rebuild
-
Seat and Opel drivers who need space-saving solutions for Leon, Ibiza, Astra, or Corsa
Besides the actual recone kit, the enclosure volume of the subwoofer also plays a central role. A typical sealed enclosure (closed box) holds 20–30 liters, while a bass reflex enclosure can range from 35 to 50 liters or more. Depending on trunk space, replacing the defective subwoofer with a recone kit offers a cost-effective alternative to a complete new purchase.
If further modifications to the doors or panels are necessary, it's worth checking out suitable door insulation or damping mats in the online shop. They prevent annoying vibrations at high volumes and ensure cleaner bass reproduction. If you want to invest as little time as possible but achieve perfect results, you can have the kits installed by professionals in Frankfurt Oder.

Variations and performance data at a glance
Below is a compact overview of common power ranges and variants covered by many 12" (30 cm) recone kits:
- RMS power: 800 W – 3,000 W
- Max. power handling (peak): up to 6,000 W
- Recommended amplifier power: from 500 W RMS per voice coil
- Number of voice coils: single-coil or dual-coil
- Coil impedance: 1 Ohm, 2 Ohm, or 4 Ohm
- Mechanical Xmax (mm): between 12 mm and 26 mm
The right choice depends on whether you value maximum sound pressure level (SPL) or finely resolved sound reproduction. For powerful R&B or hip-hop beats, a large voice coil with high RMS rating is recommended. A wide frequency response and moderate volume optimization benefit from less power-intensive kits.
