Polk Audio Signature S30chat_bubble_outlineFrom real comments

Low dialogue volume is the most common complaint among S30 owners. Several commenters independently reported that dialogue sounded too quiet relative to movie scores and effects, forcing them to turn up the center channel or add a subwoofer for balance. Others fixed the issue by re-running Yamaha YPAO calibration or manually boosting center channel dB levels and equalizer settings, suggesting the problem is often correctable through proper setup rather than a hardware flaw.

Biamping the S30 alongside matched towers noticeably improves performance. Multiple users recommended biamping the S30 together with S55 tower speakers, describing a 'huge' audible difference in sound quality compared to running them un-biamped. One owner planned to biamp again after testing without it and confirming the gap, while another said biamping alone resolved their dialogue clarity concerns without needing further tweaks.

Its size and setup requirements catch some buyers off guard. At least one owner admitted not checking dimensions or measuring their space before ordering, leading to a poor fit, while another chose the thinner, longer S35 instead specifically to avoid blocking their TV screen. A separate commenter asked about the speaker's depth for placing a TV on top, showing size is a recurring practical concern when planning placement.
