Seas Performance automotive woofer, PW165/1 L0018-04S
High Quality automotive woofer.
A glass fibrecone, and a stiff low loss rubber surround carefully matched to each
other, result in a smooth frequency response, and a clear, precise reproduction of the critical midrange area.
A relatively large voice coil diameter results in high power handling capacity.
The magnet system with a T-shaped cross section of the pole piece gives low
modulation distortion.
The bullet shaped phase plug reduces compression due to temperature variations in the voice coil and avoids resonances that would occur in the volume between the
dust cap and the pole piece and increases the power handling capacity.
The extremely stiff and stable injection moulded metal basket keeps the critical
components in perfect alignment.
