The 2¾” transducers SW070WA01 (4 ohm) and SW070WA02 (8 ohm) were designed especially for high quality multimedia and lifestyle speakers, where space otherwise usually does not allow for “real bass”. Ideal for combining with the Wavecor FR070WA 2¾” fullranges or any good tweeter.
FEATURES
True subwoofer design for vented or sealed enclosures
Dual neodymium magnet structure for high efficiency and almost ideal magnetically shielding
Black anodized alu cone for better heat transfer
Vented polymer chassis for lower air flow speed reducing audible distortion
Vented voice coil former for reduced distortion and compression
Heavy-duty black fiber glass voice coil bobbin to reduce mechanical losses resulting in better dynamic performance and low-level details
Large motor with 26 mm voice coil diameter for better control and power handling
Low-loss suspension (high Qm) for better reproduction of details and dynamics
Black motor parts for better heat transfer to the surrounding air
Conex spider for better durability under extreme conditions
Gold plated terminals to ensure long-term trouble free connection
