VEVOR 645-BT 6.5-Inch Bluetooth Ceiling Speakers: features, specs, who it suits

The VEVOR 645-BT is a set of four 6.5-inch flush-mount ceiling speakers, one of which has Bluetooth built in. They are designed to be fitted into a ceiling or wall in a kitchen, living room, bedroom or covered porch, so music fills a room without speakers taking up shelf space. Here is what the specs mean and how the system goes together.

Main and secondary speakers

Per the listing, the built-in Bluetooth chip sits in the main speaker, which pairs with a phone, tablet or computer. The other speakers connect to it by wire, and the package includes four 16.4 ft (5 m) speaker cables for connecting the secondary speakers. The main speaker also takes the power adapter. VEVOR says up to three secondary speakers can be connected in series. Wireless streaming therefore goes to the main unit, which then drives the whole group.

Drivers and sound

Each speaker has a 6.5-inch woofer and a 1-inch tweeter. In general, the woofer handles bass and mid-range, while the small tweeter handles the high frequencies. VEVOR rates each speaker at a 150W peak power, with a frequency response of 68Hz to 20kHz. The 68Hz low end means the speakers will not reproduce the deepest bass, so a subwoofer may be an option for some people. The 8Ω impedance is a standard figure, and 89dB sensitivity describes how loud a speaker plays for a given input. Peak power is a short-burst number, not continuous output.

A rubber sealing strip and ABS housing are meant to reduce audio leakage, according to VEVOR.

Grille and appearance

The grille detaches for cleaning, and VEVOR says it can be painted to match your walls. If you paint it, light coats help to avoid blocking the openings that let sound through.

Installing

VEVOR describes the process as follows:

1. Cut a hole of about 6.4 inches (162 mm) in the ceiling.
2. Fit the speaker and secure it with the mounting buckle.
3. Connect the power.

Each speaker measures 7.5 inches in diameter and 3.4 inches deep (190 x 86 mm), so check there is room above the ceiling for the depth. Before cutting, look for joists, pipes and wiring, and follow local building and electrical codes and the manual.

What's in the box

Four ceiling speakers, four 16.4 ft speaker wires, a power adapter and a user manual.

Who it suits

The kit suits those who want background music in a room, such as a kitchen or bedroom, with a clean, built-in look. The listing also names covered outdoor porches, which means a sheltered space rather than open weather.

What to check before you buy

• Room layout: think about where four speakers go and how cables will run, especially from the main unit to the others.
• Ceiling depth: make sure you have clearance for the 3.4-inch depth and the 6.4-inch cutout.
• Power: the adapter needs a nearby outlet for the main speaker.
• Bluetooth range: only the main unit is wireless, so position it close to where you will play music from.
• Bass expectations: check the 68Hz low end against how you listen.
• Outdoor use: keep to covered areas only.
