In spite of small size sound is very nice iam using it with a subwoofer and with my yamaha A4A AV receiver i like it iam hearing mostly heavy metal and the speakers have a nice punch and attack

compact surrounds that blend well with the right setup
Size: 4” Woofer
I picked up the Klipsch R‑40M as part of a full 5.1 system built around the R‑50M fronts and the R‑50C center. My original plan was to use another pair of R‑50M speakers in the back, but they simply didn’t fit in the rear cabinet space I have. The R‑40M ended up being the only model that fit comfortably, so they became my surround channels.
In terms of build quality, they feel solid and consistent with the rest of the Reference Next‑Gen line. The copper woofers and updated horn design give them the same visual identity as the larger models, which helps the whole system look cohesive. They’re compact enough to place in tighter spaces without compromising too much on performance.
Sonically, the R‑40M does a respectable job as a surround speaker. Effects are clear, directional cues are easy to follow, and they integrate smoothly with the more powerful R‑50M fronts. That said, they are noticeably less powerful than the R‑50M, so you need to spend a little time balancing your levels. Once I bumped their channel trim a bit and adjusted the distance settings, the rear soundstage locked in nicely and felt much more even.
They won’t deliver the same fullness or dynamic punch as the larger models, but for rear channels that’s usually not a deal breaker. What matters is clarity and consistency, and the R‑40M handles both well. Movies with active surround mixes feel immersive, and ambient effects wrap around the room without calling attention to the speakers themselves.
If you’re building a system where space is limited in the back, the R‑40M is a practical and capable choice. Just be prepared to fine tune your calibration so they match the output of the bigger speakers up front. Once dialed in, they round out a 5.1 setup very effectively.

Great Bang for the Buck!
Size: 5.25” Woofer
These R50 Studio Monitors are worth every penny. One could easily spend a heck of a lot more to get less. Have been a pro audio engineer my entire life. These monitors kick out clean, solid bass and accurate highs. Klipsch did a excellent job designing these monitors. Perfect for smail spaces where fidelity is critical. If you wall mount these, make sure you leave at least a 1.5 inch air gap between the back of the monitor and the wall. These units are sweet.

Worth the price
Size: 5.25” Woofer
I had in ceiling front speakers and went with these instead. The front ceilings are now height speakers. Sounds great now.
