Yamaha HS5 Speaker Test

Yamaha HS5 Speaker Test: Cabinet Resonance and Frequency Sweep Guide

For the Yamaha HS5, the 5-inch cone woofer and 1-inch tweeter are biamplified at 70 watts total.¹ Its white cone woofer is a signature identifier, but the acoustic character is the point: the HS5 is deliberately flat through the midrange and lower treble, making it one of the most widely used nearfield references for mix translation. The rear port is tuned near 60–80 Hz, and the cabinet itself is where the HS5's most diagnostically interesting test frequency lies.

At frequencies between 80 and 100 Hz, some HS5 units exhibit a cabinet resonance: a slight but audible colouration on the otherwise flat sine tone.² This sits squarely in the kick drum and bass guitar fundamental range where mix decisions get made. Sweep through 75–120 Hz at moderate volume in Manual mode and listen for any frequency where the tone takes on a slightly hollow or resonant quality distinct from adjacent frequencies.

Below 54 Hz, the HS5 rolls off quickly; it is not a sub-bass monitor.³ Sweeping below 40 Hz at high levels can push the woofer toward its excursion limit, so keep volume moderate in the low-frequency range. Above 10 kHz, the 1-inch tweeter extends cleanly to 30 kHz.⁴ Use the high-frequency sweep from 10 kHz upward to verify the tweeter is operating on both channels; any loss of output in the 10–16 kHz range when comparing channels indicates a potential tweeter fault.

Testing the 80–100 Hz cabinet resonance band

In the 80–100 Hz range, the Yamaha HS5 reveals one of its most diagnostically relevant characteristics: a potential cabinet resonance that falls directly in the frequency band where kick drum body and bass guitar fundamentals sit in most pop and rock productions.² Sweep from 75 Hz to 120 Hz using Manual mode at moderate volume, advancing in 3 Hz steps and holding each frequency for three to four seconds. Listen for any point where the sine tone develops a hollow, tubular, or resonant coloration absent from adjacent frequencies.

Confirming the coloration source is the cabinet and not the room

Cabinet resonances appear consistently at the same frequency regardless of your position in front of the monitor. Room modes, by contrast, shift in character or intensity when you move your head 30–40 cm.⁵ To distinguish between the two, note the frequency where you hear the coloration, then move your listening position 40 cm to one side while the tone plays. If the character stays identical from both positions, it is the cabinet. If it changes or diminishes, it is a room mode interacting with your original listening position.

When to accept the resonance versus when to investigate further

A 2 dB resonance within a 10 Hz band in the 80–100 Hz range is a known HS5 characteristic that does not indicate a faulty unit.⁶ A resonance that changes character between the left and right unit of a matched pair, or that produces a 5 dB or larger peak audible on program material, warrants further investigation: that degree of asymmetry suggests a manufacturing tolerance difference rather than a shared design property of the HS5 enclosure.

Channel matching before critical mix sessions

When both HS5 units are in use for stereo mixing, a pre-session channel match confirms both monitors are behaving identically at the reference frequency before critical decisions are made. Sweep to exactly 1 kHz and hold the tone for 10 seconds while listening to both channels simultaneously with your head centred between the speakers. The HS5's design is deliberately flat through the midrange and lower treble, so any audible level or character difference between channels at 1 kHz reflects either a gain mismatch in the signal path or a driver condition difference between the two units, not the monitor's voicing.⁴

Extending the channel match across the midrange

After confirming 1 kHz channel balance, extend the check by sweeping slowly from 500 Hz to 4 kHz in Manual mode. Listen for any frequency where one channel sounds louder, brighter, or differently textured than the other. A symmetric pair should produce identical sweep character on both channels throughout this range. Frequency-specific imbalances between channels indicate a crossover component difference or a driver cone condition that has developed asymmetrically over time.

Verifying the sweep result matches reference mix behavior

After the channel match sweep, play a reference track you know well and listen at 80–100 Hz and in the 2–4 kHz range. If the resonance you found during the sweep corresponds to a frequency where the HS5 consistently sounds different from other monitoring references, you now know the monitor characteristic responsible, and you can account for it without attributing it to the room or the recording.

The habit of running a reference track after the sweep turns an abstract measurement into something you can hear on real material. Because the HS5 is voiced flat through the midrange, a coloration that shows up on the sine sweep should also be audible on familiar program content, which makes it easier to decide whether to work around the monitor characteristic or treat it as a room issue. Keep the listening level consistent between the sweep and the reference so the comparison stays meaningful; verify HS5 channel balance on a sine tone before you commit to a channel-match verdict.
