78 mm 8Ω 5W Speaker Drivers, Pair
Build a small audio enclosure around a matched pair of drivers. These square 78 mm speakers are rated at 8Ω and 5W each. They are for DIY users matching passive drivers to an amplifier and enclosure.
- ✅ Build a two-driver project — Two speakers are supplied in the pack.
- ✅ Match a small enclosure opening — The square three-inch format gives a defined fitting size.
- ✅ Choose around amplifier compatibility — Stated impedance and power help check the electrical match.
- ✅ Use your own audio source — Passive drivers integrate with suitable external amplification.
Choose the amplifier and enclosure together
Check the amplifier's supported load and output before connecting the drivers. The rated impedance is 8Ω and power is 5W; wiring two speakers changes the load presented to the amplifier.
The driver has a non-paper diaphragm and metal construction details. No verified ingress rating is supplied, so a water-resistant description should not be treated as permission for outdoor exposure. These are components rather than complete Bluetooth speakers.
