Core Technical Specifications
· Audio Output Power (RMS):
o Standard Performance: Typically 3W to 10W RMS total.
o High-End Performance: Models like the Creative Pebble Pro can reach 30W RMS (60W Peak) when connected to a 30W USB-PD adapter.
· Frequency Response:
o Mini Speaker Range: Generally 80 Hz to 20,000 Hz.
o Note: Smaller drivers often struggle below 100 Hz without a dedicated subwoofer.
· Driver Configuration:
o Primary Drivers: Dual 2.0-inch to 2.5-inch full-range drivers.
o Bass Enhancement: Often includes passive radiators to improve low-end response without increasing size.
· Impedance: Typically 4 Ohms, which allows the speakers to draw more current for higher efficiency and louder output in low-voltage USB setups.
· Signal-to-Noise Ratio (SNR): Look for ≥75 dB to 86 dB. Higher values indicate cleaner sound with less background hiss.
· Connectivity & Interface:
o Wireless: Bluetooth 5.3 or higher for low-latency gaming.
o Wired: 3.5mm AUX-in and USB-C Audio for lossless digital transmission.
o Pass-through: Dedicated 3.5mm ports for Headphone- out and Microphone-in.
· Total Harmonic Distortion (THD): High-quality units maintain ≤1% at 80Hz–20kHz to ensure vocal clarity even at high volumes
