If voices are hard to hear on a Sonos TV setup, test Speech Enhancement before paying for rear speakers. The setting addresses dialogue clarity, while surrounds serve a different purpose.
Make the comparison repeatable
Choose a short TV scene where speech is hard to follow and play it from the same source at the same volume. In the Sonos app, check the controls for your home-theater room. Sonos documents Speech Enhancement for TV audio; available choices can vary by product. Compare off and on from your usual seat.
Decide based on the problem you hear
Write down whether words became clearer and whether the overall sound remained comfortable. If dialogue improves, leave a speaker purchase out of the initial budget. If dialogue is still difficult only on one source, test another title before changing equipment. If the actual goal is rear effects rather than clearer voices, compare compatible surround options separately.
