Klipsch R-51M Review
Klipsch R-51M is an incredible speaker for getting a place in the living room within a reasonable budget. This Reference series bookshelf speaker has robust sound quality and an elegant design. It bears Klipsch’s traditional horn-loaded tweeter with an excellent quality woofer for a perfect high and low-frequency response balance. This is what makes the overall sound quality awesome.
If we compare it with another bookshelf speaker of the same price range, this is one of the best. Now let’s review some of its highlighted features for your better understanding.
Design
All the Klipsch speakers come with a simple structure but contain a premium-quality look. A pair of speakers from Klipsch is enough for impressing the guest only.
This R-51M also holds the same tradition with a gorgeous look. There is not much design on the speaker’s body, which increases the beauty more.
The Bass reflex enclosure and wood grain vinyl finish are perfect for beautiful design and sound. Because the structure also helps to get an excellent sounding system.
The Bass reflex enclosure and rear-firing port ensure enough airflow, so the sound doesn’t distort or vibrate.
There is a copper color woofer on the front side with a square-shaped horn with a circular throat. The woofer looks shinny and enhances the overall beauty of the speaker.
But if your kids or pets can cause harm to the woofer, or in case you don’t want the front side left like this, use the detachable grill. Attach or remove anytime you wish for.
There is the logo of Klipsch REFERENCE inside the horn.
This boxy shape bookshelf is not too big or small but is a perfect size. Place it with your TV or home theater, on a table, or in your bedroom wherever you want.
This speaker is just going to bring a lot of praise for you at first glance.
Features
This bookshelf speaker is stuffed with numerous features and nothing less than any tower speaker. The sound quality is dynamic, and a couple of reasons or parts are responsible for that.
Tweeter
90° x 90° Tractrix® horn with 1″ LTS aluminum diaphragm compression tweeter is all that a bookshelf speaker needs to produce a dynamic high-frequency response.
LTS or Linear Travel Suspension is a clever mechanism for getting the high frequency without distortion. It minimizes unwanted vibration or distortion as much as possible; thus, clear, detailed highs improve the whole audio quality.
Moreover, the aluminum diaphragm compression tweeter that is the material is solid quality. High-quality tweeter material is needed too. Nowadays, many suitable tweeter materials are available, such as titanium and magnesium. The aluminum tweeter is counted among the best-performed ones.
Last of all, the 90X90 tractrix horn, which belongs to only Klipsch. With a circular throat and square shape mouth, this horn helps to get the desired sound directly hit the listener’s ears.
It minimizes unwanted reverb and artificial effects.
In a word, Klipsch consumed the best tweeter technology even in this price range. This is really praiseworthy.
Woofer
The woofer is closely connected with a tweeter or high-frequency. Because only woofers are responsible for producing low-frequency and getting the best quality sound, you both need low and high frequency good enough.
But Klipsch also showed their dedication by making extremely light-weight copper spun magnetically shielded IMG woofer, yet rigid. The size is 5.25-inch which is absolutely perfect for delivering powerful bass.
This type of construction is undoubtedly suitable for a tight, punchy bass. This bookshelf speaker would be a choice of the dream for the bass lovers.
Also, good quality bass can simultaneously make the whole audio quality; bad quality bass can ruin the entire audio experience.
So, just be careful while choosing a speaker and check the woofer and tweeter performance with another criterion.
Rear Air-Flow Port
Klipsch made a big hole in the back of these speakers to let air flow through. This way, air can get out more easily, which will make the bass sound hit harder.
But it’s important to note that these loudspeakers don’t have the best range of low sounds. Because they can’t go lower than 62 Hz, you can miss parts of the instruments and maybe even some voices.
But you can always use a subwoofer to make up for the frequencies you lost. You’re in luck, because Klipsch makes a subwoofer that looks just like the R-51M.
Power handling capacity
Klipsch R-51M has an RMS power 85-watts and peak at 340-watt. This speaker works at 85-watt continuously and can reach the peak at 340 watts.
To maintain the whole performance, 85-watt is good enough, but Klipsch could do a bit better with the RMS power. Apart from this, there is no complaint about the peak power.
Impedance
The lower the impedance rate, the more efficiently the speaker can pass through the electrical signals, the audio signal basically. Impedance is measured in ohms, and it is crucial to check out the impedance rating.
R-51M has an 8-ohm impedance which is pretty good, and most of the speakers maintain this rating. With this rating, this speaker can transfer signals efficiently and smoothly.
But rating lower than this is better, but that does not mean 8 Ohm is not enough. As already mentioned, most of the speakers maintain this rate, so you don’t have to be much worried about this.
Sensitivity
For the loud music lover, this point is the most important. If you are a loud music freak, then this speaker is for you. Though this is a bookshelf speaker, it still delivers a loud sound like a tower speaker.
With a 93 dB sensitivity rating, this speaker performs like a beast.
Sound Performance
The Klipsch R-51M is a great speaker for the price, and its sound makes it stand out from other speakers. They are full of life and energy, play great music, and pack a punch that will make you tap your toes and smile. Their music is surprisingly big, but it’s not quite realistic. That makes them look bigger than they really are. I was happy to find out that they work really well as background music because they have a great sense of presence and can fill the space very well. You don’t have to sit in the front row to enjoy good sound.
Even though high-pitched sounds may not be very clear, I didn’t find them annoying. Even with the volume turned down, these speakers sound great. If you use the volume control, you don’t have to turn up the sound as much as you do with some other speakers. Even at low volumes, the R-51M sounds great, which is great for you and your neighbors if you want to watch movies or listen to music late at night.

We would recommend SS-CS5 for those with a tight budget or who only want a speaker for movie nights and some music.

Klipsch RB-51 II is available for under 200$, and this is almost 100$ lesser than R-51M. Still, RB-51 II is giving tough competition with its reliable performance.

This makes the sound quality almost the same, but sensitivity, frequency response, and a couple of other things make a slight difference. This means the R-51M is a bit better with the sound quality.

Considering all facts for the Dolby Atmos lover, you should go for Jamo S 803.
Klipsch R-51M VS Dali Spektor 2
Dali Spektor 2 is the most expensive speaker on our list. The performance is decent but not dedicated as R-51M.
Dali Spektor 2, of course, is much more expensive than R-51M. With the price range, Dali could not full fill our expectations.
When we have enlisted speakers like Jamo S803 and RB-51 II at an affordable price, we also performed much better than Dali. Dali should have been more conscious about the features as they decide how the sound quality becomes.
