Frequently asked questions
Does the 3 inch woofer driver work on its own?
No. The 3 inch woofer driver has no battery, Bluetooth, USB or case. It needs an enclosure, speaker wire and an amplifier before it makes sound.
What amplifier suits a 4 ohm 15 W driver?
Choose an amplifier that is stable at 4 ohm and does not push far past 15 W into this driver, and turn it down if you hear distortion.
Will this driver fit my speaker box?
Compare your cut-out with the driver's 70 mm square frame, 60 mm hole spacing and 45 mm depth. Measure the old part first if you are making a repair.
Is this woofer driver waterproof?
No. The maker lists this woofer driver as not waterproof, so build it into a dry, indoor enclosure, and disconnect the amplifier before you solder.
