 | Wavecor WF138WA01-01 (ea.) midbass driver's product information |  |
|
WF138WA01 is a mid/woofer designed for demanding bass and midrange applications. It works equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups.
It is powered by a dual neodymium magnet structure that ensures good efficiency and optimal T/S parameters, and at the same time offers extremely good magnetical shielding.
The large 32mm voice coil and the special heat sink ensure high power handling - thermally and mechanically
The optimized paper cone ensures wide bandwidth and low distortion. Distortion is further reduced by efficient venting of chassis and voice coil.
WF138WA01 is an obvious choice for compact 2-way speaker systems.
Features
- Heat sink for increased heat transfer obtaining high long-term power handling
- Vented voice coil former for reduced distortion and compression
- Vented chassis for lower air flow speed reducing audible distortion
- Heavy-duty black fiber glass voice coil bobbin to increase power handling and reduce mechanical losses resulting in better dynamic performance and low-level details
- Large motor system with 1¼" voice coil diameter and dual neodymium magnet for better control and efficiency
- Dual neodymium magnet structure for almost ideal magnetical shielding
- 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
- Gold plated terminals to prevent oxidation for long-term reliable connection
