What this 8-inch subwoofer delivers

The WF 8"-890 is an 8-inch car subwoofer built around a 4-ohm impedance and a 50-watt RMS power rating. Its paper cone with a foam edge and a 1-inch voice coil are designed to add low-frequency depth to factory or aftermarket audio systems in cars, trucks or boats.

Behaviour during extended play

A 90-millimetre magnet and Kapton paper heat sinks help dissipate heat so the voice coil can sustain output over longer listening sessions. The forged iron T-yoke and Y-30 ferrite magnet assembly keeps the magnetic field stable, while the flexible spider controls cone movement to reduce distortion when the driver is pushed continuously.

Check before ordering

Verify that your enclosure volume and amplifier can match a 4-ohm load rated for 50 watts RMS. Confirm the mounting cut-out suits an 8-inch frame and that the wiring in your vehicle can handle the current draw without voltage drop.

Questions about this item

How much heat does the 1 inch voice coil with Kapton paper heat sinks dissipate during all-day playback?

The Kapton paper heat sinks on the 1 inch voice coil are designed for proper heat dissipation and voltage sustainability during extended use.

What amplifier impedance must I already have to match this subwoofer's 4 Ohm rating?

You need an amplifier stable at 4 Ohms to correctly drive this subwoofer's rated impedance.

Will the 90x36x17 mm ferrite magnet fit the cutout in my existing 8 inch speaker enclosure?

The magnet measures 90x36x17 mm; verify your enclosure cutout and depth accommodate these dimensions before installation.
