How we ranked these studio monitors
Every pick ranks in Amazon's best-seller list for its category and has a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: studio monitors for mastering
Woofer size sets the low end
A larger woofer reaches lower frequencies, so compare the woofer size and the low-frequency reach together. The StreamEye HS8 pair uses 8-inch woofers and reaches 38Hz, with a subwoofer that reaches 22Hz. The pegcabac PMH-6A uses 6.5-inch woofers and reaches 60Hz, while the NUX AXON 3 uses 3-inch woofers and reaches 55Hz. For mastering, the low end matters because bass decisions shape the whole mix, so pick the reach that covers the lowest notes you work with.
Match the inputs to your interface
Check the outputs on your audio interface against the inputs on the monitor. The StreamEye HS8 pair and the pegcabac PMH-6A take balanced XLR or 1/4-inch TRS inputs, so they plug straight into an interface, console, or DAC. The NUX AXON 3 takes USB DAC, Bluetooth, 1/4-inch stereo, RCA, and 1/8-inch AUX inputs, so it links to computers, mobile devices, and vinyl systems. Pick the monitor whose inputs match the outputs you already use.
Use the room controls to calibrate
A monitor sounds different against a wall than in open space, so use the controls the maker provides. The StreamEye HS8 pair has back-panel ROOM CONTROL switches that cut -2 dB or -4 dB below 500 Hz, and HIGH TRIM switches that adjust plus or minus 2 dB at high frequencies. The NUX AXON 3 has magnetic footpads that tilt +9° and -5° to aim the sound at your ears, and an Acoustic Correction EQ app. Set the controls once for your room, then leave them alone while you work.
Frequently asked questions
Do I need a subwoofer for mastering?
Not always. The StreamEye bundle includes an 8-inch subwoofer that reaches 22Hz, while the NUX AXON 3 reaches 55Hz and the pegcabac PMH-6A reaches 60Hz on their own. Choose the subwoofer when your work needs the bottom octave the monitors alone do not cover.
What inputs do these monitors take?
The StreamEye HS8 pair and the pegcabac PMH-6A take balanced XLR or 1/4-inch TRS inputs. The NUX AXON 3 takes USB DAC, Bluetooth, 1/4-inch stereo, RCA, and 1/8-inch AUX inputs. Match the monitor to the outputs on your interface.
Can I mount the NUX AXON 3 on a stand?
Yes. The AXON 3 has a 3/8-inch socket on the bottom for mounting on a microphone or speaker stand. It also has magnetic footpads that tilt +9° and -5° for desk use.
