Klipsch THX-5002-L In-Ceiling Speaker

The Klipsch THX-5002-L is a premium THX Ultra2-certified in-ceiling speaker built for big, dynamic home theater sound without visible floor speakers.

Klipsch THX-5002-L Full Q&A:

Is the THX-5002-L a good choice for a dedicated home theater?

Yes. Its THX Ultra2 certification and horn-loaded tweeter are designed for cinematic dynamics, clarity, and controlled coverage—ideal for immersive surround layouts.

What makes this speaker different from typical in-ceiling speakers?

It pairs dual Cerametallic woofers with a VCT horn-loaded titanium tweeter and a tuned bass-reflex chamber, delivering higher output, cleaner dynamics, and more consistent performance.

Will bass performance change depending on my ceiling space?

It’s designed to stay consistent. The woofers operate in an enclosed tuned-port chamber to help reduce variability caused by different ceiling air volumes.

What amplifier power should be used with this speaker?

Choose a quality amplifier or AV receiver appropriate for the room and listening goals—power handling is rated at 100W continuous / 400W peak.

What size cutout do I need for installation?

Use a 13.39" cutout diameter/template. The speaker opening/hole dimension is listed as Ø 13.25", so follow the provided cutout spec for proper fit.

How deep does the ceiling cavity need to be?

Plan for roughly 9.5" mounting depth (with additional published depth references around 9.23"–9.38" depending on measurement point), ensuring safe clearance above the ceiling.

Can the grille be painted to match my ceiling?

Yes. The grille is white and paintable, designed to blend into the ceiling and keep the installation visually minimal.

Can I mix this with other Klipsch THX speakers?

Yes. It’s designed to be timbre matched to Klipsch THX-certified products, making it easy to build a cohesive multichannel system.
