Compact 2-Inch Arduino Speaker Pair
This pack supplies two 2-inch 4-ohm 3-watt full-range drivers intended for hobbyists building Arduino audio projects or repairing small Hi-Fi equipment. The wired 2.0 configuration suits breadboard experiments and permanent solder-in installations alike.
Steady 3-Watt Output With Bass Boost
Each driver delivers a continuous 3-watt RMS rating so extended playback does not trigger thermal compression the way a short burst rating would. The integrated bass-boost feature reinforces low frequencies down to the 190-hertz resonance point while the 77-decibel sensitivity keeps output consistent during long listening sessions.
4-Ohm Impedance Matches Low-Voltage Boards
The 4-ohm load is the critical specification because it allows direct connection to typical 1.5-volt to 6-volt Arduino supply rails without an external amplifier stage. Builders needing higher power or a different impedance must select another driver.

Questions about this item
How much heat or noise does a 3 W, 4 ohm driver produce when run continuously?
At 3 watts RMS the drivers stay cool and silent; there is no fan or amplifier inside the speaker itself.
What external amplifier or wiring must I already have to drive these 4 ohm, 3 W speakers?
You need a 4 ohm-capable amplifier or microcontroller board with speaker outputs, plus two-conductor wire for each unit.
Will these 2 inch, 190 Hz resonance speakers work alongside the 3 inch, 20 W model listed in the same range?
Yes, both share 4 ohm impedance so they can run from the same amplifier, but the larger unit handles more power and plays lower.
