1. Φ52mm vs Φ60mm: Yuav ua li cas xaiv qhov zoo TV soundbar tsav tsheb loj?
TV soundbar enclosures feem ntau yog 0.3L txog 1.2L. Cov neeg tsav tsheb loj tshaj Φ40mm mus rau Φ66mm, tab sis nyob rau hauv 2026 cov ntaub ntawv ntau lawm, Φ50-Φ57mm band nqa cov khoom xa tuaj loj tshaj plaws (sau los ntawm pej xeem kev lag luam qhov chaw 2026-Q2). Qhov no muaj qhov sib npaug zoo tshaj plaws ntawm qis-kawg txuas ntxiv (F0 feem ntau 95-130Hz) thiab nruab nrab clarity.
| Tsav txoj kab uas hla | Tej qhov rooj | F0 ntau | Zoo tshaj plaws |
|---|---|---|---|
| Φ40 hli | 0.15-0.4L | 130-180Hz | Compact soundbar / mini bar |
| Φ50 hli | 0.4-0.8L | 110-140Hz | Mainstream 2.0 TV suab |
| Φ52 hli | 0.5-0.9L | 100-130Hz | TV soundbar / desktop bar |
