Herdio 4" Bluetooth Ceiling Speakers 240W Flush-Mount

Herdio 4" Bluetooth ceiling speakers are a flush-mount, two-way pair with Bluetooth 5.0, a wall-mount receiver, and enough power for clear background and home-theater audio.

These Herdio in-ceiling speakers combine a compact 4-inch full-range driver with a dedicated in-wall receiver that supports Bluetooth streaming, USB playback, AUX input and microphone paging. The system is built for neat installation into standard ceiling cavities and delivers usable volume and clarity for kitchens, bathrooms, home theaters, offices and living rooms.

How do these speakers connect to my phone and other devices?

The built-in Bluetooth 5.0 module provides a fast and stable wireless link to smartphones, tablets and other Bluetooth sources for streaming music and podcasts. If you prefer wired connections, the included wall receiver accepts AUX inputs and reads USB flash media while also supplying a USB charging output.

• Bluetooth 5.0 for quick pairing and improved range.
• 3.5mm AUX input for non-Bluetooth sources.
• USB flash reader for direct playback plus device charging.
• Wall plate receiver with sample audio control and mic input for paging.

What sound performance should I expect from a 4-inch speaker?

Despite the compact driver size, these Herdio speakers are tuned to deliver clear midrange and intelligible vocals, with RMS power rated at 30W per speaker and peak capability up to 120W. Sensitivity around 89dB allows them to produce satisfactory volume in ordinary rooms without demanding excessive amplifier power.

• 4-inch full-range driver for balanced mid and high frequencies.
• 30W RMS per speaker; 120W max handling for dynamic peaks.
• ~89dB sensitivity for efficient acoustic output in small-to-medium spaces.

How easy is installation and where will these fit?

Herdio designed these speakers for flush in-ceiling or in-wall installation using a round cut-out sized for standard cavities. The bezel and grille sit nearly flush to preserve ceiling aesthetics, and the overall depth is compact enough for typical joist and attic clearances.

• Flush-mount design for discreet ceiling integration.
• Total diameter 5.91" (15 cm); cut-out diameter 4.73" (12 cm).
• Speaker depth 2.76" (7 cm) — fits most ceiling cavities.

What accessories are included and how does the wall receiver expand functionality?

The package contains two speakers with wiring, a power adapter, an in-wall receiver plate and a user manual so you have everything needed for a standard dual-speaker installation. The wall receiver centralizes input options, gives you basic source control and adds a microphone input for paging or announcements.

• Included: two 4" speakers, two speaker wires, power adapter and manual.
• In-wall audio receiver plate for Bluetooth pairing, USB/AUX connections and mic input.
• Receiver doubles as USB charger and media reader for flash drives.

Who is this for? The Herdio 4" Bluetooth ceiling speaker pair suits homeowners and small business operators seeking a tidy, wired-or-wireless audio solution for background music, voice paging and casual home-theater use. It’s ideal where ceiling-mounted speakers are preferred for clean sightlines — kitchens, bathrooms, home offices, small living rooms and retail counters will all benefit from the compact size, versatile connectivity and straightforward installation.
