White 2.0 Bluetooth speaker system
The Microlab SP-H21WH is a 2.0 desktop speaker pair delivering 66 W total power from two wooden cabinets finished in white leather. Each cabinet houses a 3.5 inch German-patented woofer and a 1 inch Peter Larson silk dome tweeter with a Kurt-Muller dome diaphragm. Bluetooth 2.1 connectivity uses a CSR chipset supporting A2DP and AVRCP profiles for wireless streaming.
Upgrade from basic monitor or laptop audio
This system replaces integrated monitor speakers or single-piece sound bars that lack stereo separation and low-frequency authority. The two-way driver arrangement and 50 Hz to 20 kHz frequency response add audible bass weight and clearer treble detail. The jump is worth it when you want true left-right imaging and a dedicated amplifier rated at 18 W RMS per channel without adding a separate subwoofer.
Handles near-field music, films and gaming
At typical desk distances the 66 W output and >70 dB signal-to-noise ratio provide clean volume for music playback, movie dialogue and game effects. The 3.5 inch woofers reach down to 50 Hz, so electronic bass lines and explosion rumble remain present, though deep sub-bass below 50 Hz is not reproduced. Analogue RCA and 3.5 mm inputs are included for wired sources when Bluetooth is not preferred.

Questions about this item

What cables must be connected before the system will play sound?
Link the two cabinets with the supplied 3 metre interconnect cable, plug the DC 18 V power adapter into the right unit, then pair a source via Bluetooth 2.1 or use the 1.8 metre 3.5 mm to RCA cable.
Which driver specifications should I check if the tweeter or woofer later needs replacement?
The tweeter is a 1 inch silk dome rated at 10 Watt and 4 ohms; the woofer is a 3.5 inch unit rated at 20 Watt and 8 ohms.
