Klipsch r 51m bookshelf speaker review năm 2024

The R-51M are not your typical black box that sits in a corner, take the grills off and you will find their signature spun-copper mid-bass cone along with their Tractrix horn waveguide for the tweeter. All this is housed in an MDF cabinet with wood grain vinyl wrap for a modern yet classy finish, these will definitely attract some attention in your system.

These are well built, the MDF cabinets feel sturdy and on the back you have proper binding plugs which support 4mm banana plugs. The vinyl wrap is applied well without any obvious flaws and they feel and look great for the price. There are no fancy materials here, just well-designed drivers in a rigid cabinet, no complaints from me though.

Setup:

The R-51M are rear ported so do sound best when pulled a little away from the rear wall, however with their horn waveguide the sweet spot is a little wider than normal. They still sound best when toed in, as the sound becomes more detailed and focussed. These are relatively small, which means they will fit on a cabinet or bookshelf well, however as with most speakers of this size they sound best when placed on dedicated stands.

With a Sensitivity of 93dB @ 2.83V/1M these are pretty easy to drive, with your typical 50wpc integrated amp doing a fine job of powering these, alternatively you could use one of the cheaper class-d amps to good effect.

Sound:

From their size, you would expect the R-51M to sound small and a little lean, but you’ll be in for a surprise. They don’t have bottomless extension of larger floorstanders or subs, but they can sure pump out a hefty low end with bundles of energy. Providing they are well placed, the lows will be full without bloat, the lows are punchy and dynamic with stated low frequency extension of 62Hz +/-3dB which in room will sound a bit lower. Perfect for most music genres, however they do favour more energetic music.

The midrange comes across well separated from the lows and with a good amount of clarity on show. They don’t become overwhelming or shouty, however they cut through with a snappy response that wants you to pay attention. The presentation isn’t laid back or warm, these are not a speaker for playing at low levels in the background. This snappy response helps with layering within the midrange, keeping everything well focussed and separated.

The top end is very open, detailed and quite up front. They are not up-front to the point of being harsh, but they are always present in the mix. Snares are particularly prominent, adding great attack to the sound. That horn waveguide really helps focus the upper frequencies and extension is never an issue up top. The R-51M have a liveliness that is similar to how you would hear a live recording rather than a studio one, which will appeal to quite a few people.

Overall they have a good balanced between the frequencies with a full yet punchy low end, open and detailed midrange and energetic treble. These are a pair of speakers that demand your attention when listening to them, and like to be enjoyed at slightly higher volume levels. Match them with the right equipment and you have a very enjoyable system if you favour energy over a smoother sound.

Conclusion:

The R-51M are an excellent speaker for the price, with a highly addictive and energetic sound that is sure to get your feet tapping. This does come at the expense of a little refinement, but this slightly rough around the edges sound is more akin to a live performance than a studio one.

My experience was great. Obi listened to my needs & provided several options & recommendations. Great customer service!

The Klipsch Reference R-51M offers excellent build quality with attractive "retro" flair for an affordable price. Sound quality is dynamic and punchy, especially with rock and pop. The speakers are very efficient and can play loudly without strain.

The Bad

Some buyers may prefer the more stately looks of the Q Acoustics or Elac competition, which also offer warmer sound and better bass.

The Bottom Line

The Klipsch Reference R-51M combines throwback looks and thoroughly exciting sound in an affordable package.

Those are high-end speakers but the company is also going retro in its affordable models, including the new Reference line. The R-51M is the "baby" of the series and packs a 5.25-inch spun-copper driver and Klipsch's signature horn tweeter into a small stand mount speaker.

As you'd expect with a retro-futuristic Klipsch speaker, the company hasn't meddled with its established sound. It's still on the brighter, more exciting side, and yet offers enough bass for modern music. Of course, it sounds even better partnered with the subwoofer of your choice. If you like your rock or pop music loud, the Klipsch can inject a dose of fun into your system for an affordable price. The Klipsch Reference R-51M is a little powerhouse. It might get by sans sub if you boosted the bass with your receiver's tone controls, or if the R-51Ms were positioned up close to a wall. It is a small speaker, one that by design forfeited its deep bass response to increase its sensitivity, which in turn resulted in its dynamic sound. That's what makes the R-51M so much fun to listen to. While the Q Acoustics are warmer and fuller and the big Elacs are better overall, especially for bass, the Klipschs are more fun. If you want speakers ready to party, the R15-Ms are it.
