Wavecor SW312WA04 12-1/4" Aluminum Cone Subwoofer 8 Ohm
Wavecor SW312WA04 12-1/4" Aluminum Cone Subwoofer 8 Ohm
The Wavecor SW312WA04 is a 12-1/4" aluminum cone subwoofer that was designed to perform equally well in home theater or hi-fi installations. The extremely stiff aluminum cone, the long linear throw, exaggerated ventilation, and the special dynamic linearization short circuiting rings together make up for an unusually linear and low-distortion woofer.
- Power Handling (RMS) 250 Watts
- Power Handling (MAX) 300 Watts
- Impedance 8Ω
- Frequency Response 29 to 300Hz
Wavecor SW312WA04 12-1/4" Aluminum Cone Subwoofer 8 Ohm
SW312WA03 and SW312WA04 are woofers designed for dedicated sub bass applications. They work equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups.
The extremely stiff aluminium cone, the long linear throw, exaggerated ventilation, and the special dynamic linearization short circuiting rings together make up for an unusually linear and low-distortion woofer. Even at very high signal levels, the unit behaves controlled and without distortion.
Due to low mechanical losses SW312WA03 and SW312WA04 master equally well low level details and extreme dynamic peaks.
Both models are available with black anodized alu cones as SW312WA05 (4 ohm) and SW312WA06 (8 ohm)
- Extremely rigid aluminium cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels
- New reinforced die cast alu chassis with optimal ventilation and increased stroke
- Venting through holes in cone neck for reduced distortion and compression
- Vented chassis for lower air flow speed reducing audible distortion
- Two internally built-in alu rings for stabilizing the magnetic field leading to lower high-level distortion
- Heavy-duty black fiber glass voice coil bobbin to reduce mechanical losses resulting in better dynamic performance and low-level details
- Large motor system with 2” voice coil diameter and 145 mm magnet for better control and efficiency
- Black-anodized magnet structure steel parts for increased heat dissipation and power handling
- Long linear stroke motor for reduced distortion at high levels
- Linear suspension with specially designed CONEX damper (spider) for long durability under extreme operating conditions
- 4-layer voice coil for increased control and better small-cabinet performance
