Size: 4” Woofer
Fantastic sound quality to my ears, got these used “mint” for 179 and that was a steal, they were never even opened. They feel solid and well made, they’re heavy for the size which makes them feel of a higher quality. Very happy with my purchase

    • 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. ... show more

    • Poor sound quality - too tinny (sharp)
Size: 5.25” Woofer
I was disappointed with the sound quality. While the speakers get very good reviews, the sound quality is far too tinny (sharp) for my liking, they were not enjoyable to listen to - I returned them. I replaced them with a pair of Polk XT20 speakers and the sound quality is much better for basically the same price ... show more
