WF146WA01


	Nominal impedance is 4 ohm for WF146WA01 and 8 ohm for WF146WA02. Otherwise the two models are identical. WF146WA01/02 are mid/woofers 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. Powered by a large 90mm magnet structure that ensures good efficiency and optimal T/S parameters. The large 32mm voice coil ensures high power handling - thermally and mechanically The optimized paper cone ensures large bandwidth and low distortion. Distortion is further reduced by efficient venting and an alu shorting ring stabilizing the magnetic field in the air gap. WF146WA01/02 are very good choices for compact 2-way speaker systems or even as midrange in multi-way systems.

		FEATURES

Alu field-stabilizing ring inside magnet assembly for reduced high-level distortion
Vented voice coil former for reduced distortion and compression
New 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 90mm magnet for better control and efficiency
Black magnet parts for better heat transfer to increase power handling
Long linear stroke motor for reduced distortion at high levels
New progressive 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
