SpeakerCraft AIM252 Mk3 5.25" Aimable In-Ceiling Speaker
If the ceiling has a bedroom or other living space above it, or is part of an escape route, building regulations require each speaker to have a fire hood. Hoods also cut sound leaking into the room above.
Allow about 10m per speaker for a typical run back to the amplifier. Webro 16/2 LSZH (low smoke, zero halogen) is the right cable for runs in ceilings and walls.
The SpeakerCraft AIM252 Mk3 is a 5.25" two-way in-ceiling speaker with a pivoting glass fibre woofer and an aimable three-tweeter ARC array, designed for distributed audio and immersive surround installations. Its flangeless, magnetically-attached grille and fully adjustable driver array make it well suited to living rooms, kitchens and home cinema layouts where precise sound direction is needed.
Why we like it
- ±15° pivoting glass fibre cone woofer with 30° total adjustment range for aiming sound towards the listening area
- ARC Tweeter Array with three 5/8" dome tweeters offering 359° rotation and ±15° toe-in/toe-out for directable high-frequency coverage
- WavePlane acoustic lens technology enhances high-frequency dispersion throughout the room
- Acoustic Isolation Technology decouples the speaker housing from the ceiling to reduce structural resonance and colouration
- Symmetrical and asymmetrical Linkwitz-Riley crossover design for improved phase coherence and smoother frequency response
Installation notes
The speaker requires a cut-out of 168mm and an overall diameter of 203mm, with a mounting depth of 124mm behind the ceiling, so check joist spacing and ceiling void depth before installation. It presents an 8 ohm load and is rated at 100W power handling, so pair with an amplifier capable of driving this impedance comfortably. Its voicing and crossover design make it suitable for both distributed audio and object-based surround formats such as Dolby Atmos.
