The Loudspeaker System: Stereo Immersion
The most immediate and critical audio upgrade on the Lava Agni 4 is the transition from a mono speaker to a true stereo setup. This change is essential for modern smartphones positioning themselves as multimedia powerhouses. The stereo configuration uses two dedicated drivers: a primary speaker located at the bottom of the device and the earpiece doubling as the secondary speaker at the top. This design creates a balanced, wider soundstage, crucial for watching videos and playing games.
Stereo Speaker Placement and Output
The primary bottom-firing speaker handles the bulk of the lower frequencies and overall volume. The secondary speaker, integrated into the earpiece grille, provides necessary directional sound and high-frequency details. When holding the phone horizontally in landscape mode, this dual setup delivers clear left and right channels. This spatial separation immediately elevates the experience compared to the previous mono-speaker Agni 2.
Volume levels are impressive. The Agni 4 reaches sufficient loudness to fill a small room without excessive distortion. However, initial tests suggest that pushing the volume past the 85% mark introduces some clarity issues. At maximum volume, the treble can sound slightly brittle, and the midrange lacks warmth. This is a common trade-off in smartphone speakers where acoustic space is limited.
Analysis of Sound Signature
The sound signature of the Lava Agni 4’s speakers is tuned primarily for clarity in human voice and high-frequency detail. This tuning benefits dialogue-heavy content like podcasts, news broadcasts, and standard television shows. Midrange frequencies, where most musical instruments and vocals reside, are generally present but slightly recessed. This means music playback, especially genres like rock or electronic music, can feel thin or lacking in punch.
Bass response, while present due to the stereo configuration, remains typical for a smartphone in this class. You will not feel a deep rumble or substantial sub-bass. The low-end serves mostly as a foundational element, preventing the overall sound from becoming entirely tinny. For casual listening, the speakers are more than adequate. For audiophiles or serious gamers, the speaker quality is decent but not exceptional.
