If the home audio here refers to a single speaker used at home, the difference between them is that the installation methods of the two speakers are different. The installation method of the ceiling speaker is suitable for installation on the ceiling. The second is that ceiling speakers generally have fireproof and waterproof requirements, but home audio does not need such requirements. The third is that the power of ceiling speakers is usually not large, from a few W to dozens of W. Fourth, some ceiling speakers are active, that is, with power amplifiers, and all home audio speakers are passive.
To put it simply, the smallpox of broadcasting is constant pressure. Home audio is constant resistance. In terms of speaker units, ceiling speakers generally only have tweeters, while home audio has tweeters and woofers.
