Your Whole-House Stereo System

You might have a great home stereo system in your home theater, your living room, your den -- even your bedrooms-- but you want one for your whole house. How do you solve those pesky bathrooms, closets, and hallways? Introducing the Klipsch Reference R-1650CSM, our in-ceiling speaker. It’s perfect for all those little nooks that traditional home audio can’t fill. 

The Klipsch Difference

Traditional speaker systems have three drivers that produce sound. These are called tweeters (for highs), mid-ranges, and woofers (for bass). Instead, these Klipsch speakers use a pair of dome tweeters within the woofer. 

These enhanced drivers result in more even sound coverage that fills a room with rich, immersive audio – hear the nuances of a triangle’s ting or the powerful guitar riff of your favorite rock band. When it comes to accurate sound reproduction, Klipsch has set the bar higher than ever. 

Compact and Powerful 

At the heart of the R-1650CSM is a single 6½” polypropylene woofer with a large motor structure for high sensitivity, yielding a deep, rich, and clear bass output. Adding together the stereo feeds, this woofer belts out a rich mono signal. Embedded within the woofer find a pair of coaxially (lengthways)-mounted 1” polymer dome tweeters with left and right channel feeds to preserve the stereo effect. Only a Klipsch in-ceiling speaker can provide this level of performance.  

Waterproof and Paintable 

Included with the R-1650CSM is a white aluminum grille. This grille is paintable -- allowing your speakers to blend into whatever ceiling décor your room has -- and water-resistant, allowing it to be mounted even in high-humidity environments like bathrooms and saunas.  

Pair with Our Klipsch Installation Kits 

Pair the R-1650CSM with our IK-800-C installation kit or our ME-650-C fire-rated enclosure (sold separately) to embed in the ceiling and make it look like it’s always been there.

Perfect for use in bathrooms, closets, hallways, or anywhere else multiple speakers would be impractical, the R-1650-CSM delivers powerful and dynamic performances to some of the most difficult installation locations.

  • Single speaker accepts two-channel input
  • Separate tweeters for each channel to preserve stereo effect
  • Paintable to match ceiling
  • Packaged individually

The R-1650-CSM employs a 6.5-inch polymer-cone woofer and a large motor structure for high sensitivity and strong bass output. Dual voice coils sum the low frequencies from a stereo input to mono. Upper frequencies are handled individually for the two channels by a coaxially mounted dual-tweeter array preserving the stereo effect.

The speakers mounting system makes installation a breeze while its paintable aluminum grille provides added rust protection in moisture-prone areas such as bathrooms kitchens and saunas.

While the R-1650-CSM will fit into our latest IK-650-C installation kit it can also be used in conjunction with the ME-650-C fire-rated enclosure.
