Tweeter
In this speaker, Klipsch has redesigned the horn structure for a dynamic sound stage. And from the very beginning, this brand has always been more concerned about the high frequency that is the tweeter.
Tractrix® horn with 1″ titanium diaphragm compression tweeter is used in this bookshelf compact speaker. You may have seen this tweeter in other Klipsch speakers.
This driver ensures a more detailed and directional sound that can hit the ears. A soundstage of 90°-wide, 60°-high pattern gives detailed high frequencies.
Additionally, the Linear Travel Suspension is integrated into the design to minimize the distortion as much as possible.
Woofer
Now it’s time to know about the low frequency without which you cannot expect a balanced sound profile from your speaker. There is the 4-inch Cerametallic woofer, which is lightweight at the same time rigid.
This kind of structure helps to produce the mids and bass very defined and dedicated. The edges are folded. This is another reason for the tight bass and prevent vibrations.
There is a dust cap that keeps the woofer stable but doesn’t give the woofer a messy look.
Sound Quality
Overall, it provides a great sound quality. As a bookshelf speaker for a small or average size room, nothing can be better than this. A louder, super detailed sound you can experience can turn the music, movie, or shows experience more interesting.

Features
For giving the signature of Klipsch, they always use the same type of tweeter and woofer. This always makes these brands way too different from others.
Tweeter
There is again the horn-loaded tweeter we can see in the RB-51 II speaker. 1″ titanium dome tweeter with Tractrix® horn focused more into high frequencies so the sound can directly hit the ears.
The titanium driver is one of the popular tweeter materials as the material also has a great impact on the sound. Titanium helps to produce wider high frequencies efficiently.
Again, this driver mated to 90×60 inches square Tractrix Horn so you can experience the detailed and directional sound around you.
Moreover, LTS or Linear Travel Suspension technology reduced the distortion, so there is no unwanted noise at all.
Woofer
A great quality woofer is a must in order to get the lower frequency efficiently. Otherwise, one cannot expect the powerful bass at all.
Whenever you come to see a speaker, you can see the biggest driver that is the woofer mainly. There is a saying that a big woofer means big sound and this RB-51 II has a 5.2’’ woofer which gives a rich form of bass.
Cerametallic 5.2-inch woofer makes the low frequency so dedicated. The rich punch of bass makes the audience surprised.

Frequency response
The human ear can hear sound in a range from 20 Hz to 20 kHz. This range of important for the speakers too as it decides how clarity we are going to get from our speaker.
RB-51II has a frequency response of 50Hz-24KHz. This is good and from a bookshelf speaker, this range is close to perfect.
With this range, this speaker can produce a wider range of sound.
Impedance
The lower the impedance, the more effectively the speaker can perform. 4-ohm or 8-ohm is considered the perfect impedance of a speaker.
Undoubtedly, Klipsch thinks the best for their customers, so they use 8-ohm impedance in their speakers.
RB-51 II is featured with an 8-ohm impedance.
Sensitivity and Power
If you are a music freak, then the loudest music is your favorite one. But the louder sound from a bookshelf speaker is not expected at all. But Klipsch has eradicated this myth as it is offering 92 dB sensitivity rate from RB-51 II.

This dual bi-amping feature allows the speaker to connect with an extra amp or receiver. If someone is not satisfied with the sound quality and wants more spice, than they may want to connectexternal receivers or amp. With the bi-wired feature, you can do that most easily.
Tweeter
Like RB-41 II and RB-51 II; RB-61 have the traditional horn-loaded 1-inch Tractrix® horn dome tweeter. For being a good tweeter, the shape and material are important. And in Klipsch speakers, these drivers contain superb material and shape.
For this reason, the consumer gets the crips and clear, extraordinary sound. For this kind of sound high frequency is responsible, mostly; which Klipsch has understood long before and giving a keen focus on this.
Woofer
If you are a bass lover then this speaker is only for you. Because this speaker has a big woofer that produces the smoothest low frequency. You can feel that your room would fill entirely with the bass if you place this RB-61 ii in your home.

Sound Quality
For covering a great sound quality, many criteria work such as the frequency response or power handling capacity, etc.
There is no denying the fact that Klipsch speakers always have surprised its consumer with the precise sound quality. They have their own signature sound quality.
This RB loudspeaker series is also known for the best sound quality. Like the Reference or RP series, all the speakers from RB are impressive.
RB-61 II provides an exclusive sound that slightly can change the movie, music, TV shows experience. Also, not too much expensive compared to the performance.
Frequency Response
Starting with the frequency response because this is one of the most important features that are responsible for the wonderful sound. A good frequency range considered is 50 Hz or lower, as a human can hear from 20 Hz to 20 kHz.
Luckily, RB-61 II has the range 45Hz-24KHz; which is super good for a promising sound. If you are a music lover, you can hear the music full of details and the horn is there for giving distortion-free audio.
Impedance and Power
All the speakers of the RB series have 8-ohm impedance. There is nothing much to say about this as 8-ohm is perfect for speakers.
Next, it has a 400-watt peak power and 100-watt RMS. From the previous two versions, the power range is a bit high, so you can guess how the sound has become superb.

Product Differentiator
Breathtaking sound quality and higher sensitivity rate. Best suited for home theater.
Things to improve
This is kind of bulky, so needs a lot of space.
Klipsch RB-81 II
RB-81 II has a neutral sound profile that makes this speaker number one best speaker in this series. The audio quality is distortion-free, non-fatiguing, and too much accurate.
For home theater, this can be a good option. Otherwise, if you a movie freak and want some surround sound then must go for this super budget-friendly speaker, which for sure will make your day.
Design
There is no difference in the or structure of RB series speakers. But you can get two colors of RB-81 II that are black and walnut. Personally, I prefer the walnut one because it gives a Klipsch premium quality vibe. But this is totally one’s choice.
As far as the question about durability, this speaker can be a long-run companion. The MDF enclosure is a high-quality material that is common in Klipsch speakers.
The woofer and tweeter materials are also rigid and durable. We will see about them in detail in the next section.
There is not much design in the overall structure. So simple, but contain a gorgeous and classy look. You can place it with your home theater if you have a home theater setup already. Or place it beside your bed, in your living room. This can totally match the room’s décor.
Dimension of 12.3 x 9.3 x 19.1 inches is a bit bigger than any typical bookshelf speaker. But for giving a place to the bigger woofer and being a loudspeaker, this bigger structure is required.
Feature
Like the design, there is not much difference in the features too. The same traditional woofer and tweeter are integrated into this speaker. All the RB series speakers have the same features and there is a tiny difference between them.
Tweeter
For getting a distortion-free and precise sound quality the tweeter is really important. With the material, the shape also plays a vital role in what I have discussed in the previous sections.
This RB-81 II has a 1’’ tractrix dome tweeter in a horn shape. There is the 90×60 pattern that follows this tweeter.
Just expect a robust high frequency from this speaker after not being a floor-standing speaker.
Woofer
Luckily Klipsch always gives extra care in their woofer quality and material. This is a big reason for being this popular.
Shockingly RB-81 II has an 8″ Cerametallic woofer. Can you just imagine what you can have in your home if you go to this speaker? Many tower speakers also don’t contain This kind of big woofer many times.
The saying that a big woofer means the dynamic sound is so true about this speaker. An 8-inch woofer is beyond imagination in this price range under $500. You really won’t find any best alternative.
We prepare for getting a wall-shaking sound in your home.
Sound Quality
This far you have known about 3 speakers that belong to the RB series. All of them are spectacular in all ways. The quality is great and is carrying Klipsch’s signature sounds promising.
But this RB-81 II is the best one among all other speakers in this series. The sound quality is divine and worthy of getting all the praises. This has the most updated features which are astonishing to the consumers.
Not only for movies, this loudspeaker can work better with home theater. There is no more need for many speakers for the loudest music. This can satisfy you how you want.
Also, the sound is pure and accurate. All the dialogue or lyrics you are going to hear will be crystal clear that won’t make you bored at all. You can hear the music for hours and still not tired.
This is one of the recommended speakers. If you are a fan of Klipsch, then this RB-81 II is surely the best choice.
Frequency response
I have already mentioned that frequency response under 50 Hz or equal to this can give the best audio. This speaker has a range of 44-24,000 Hz. Isn’t it amazing!
Only the high-end speakers can manage to get this range. Otherwise, you can see a lot of speakers in the marketplace with a higher frequency range. So, their sound quality can’t compete with the speakers like RB-81 II.
This is the perfect range for you to get the desired audio.
Impedance, Power, and Sensitivity
Another three important criteria for good sound quality. I have described this separately for each speaker because it is most important. If you have a basic knowledge of the speaker then you can understand what I am talking about.
The impedance rate is 8 ohms. That is absolutely great.
Then comes to power handling capacity, which is a 600-watt peak and 150-watt RMS. A continuous power supply of 150 watts can handle the performance of the speaker effortlessly.
Then the sensitivity rate is 97 dB! This is huge what makes this speaker different from all others. These loudspeaker series have really gifted a new era of loudest sound.
This can shake your walls can irritate your neighbors too. While placing these speakers be careful about the place you choose as the vibration can go to the ground.
Get the loudest music ever
This has already been mentioned that RB-81 II has 97 dB. One really doesn’t need louder than this rate. This can shake your walls and room if you would play anything in the highest volume.
Or if you ever watch movies or shows then for the louder sound it would feel much real like the lion’s roar or shooting in the action films.

RB-41 II VS RB-51 II: Loudspeaker Comparison
In this series, all the speakers contain the same structure with the same material that is used for the body. Then the traditional woofer and tweeter also are the same. So, here there is nothing to compare about them.
But the significant difference lies in the woofer size, sound quality, and maybe in the dimension or size.
First of all, talking about the woofer as they have a bigger role in the sound quality. RB-41 II has a 4-inch woofer whereas, RB-51 II has a 5.25’’ woofer. So, you know the difference already.
Then the sensitivity rate is also different. This can make a bit of difference in the loudness.
Last of all the frequency response is much better for RB-51 II as it is 50 Hz. But RB-41 II could not make it in a better way. Rather than other features, this frequency response has created a big comparison in the sound quality between these two speakers.
To conclude, none of the speakers deserve any fewer praises. Though RB-51 II is slightly better than 41 II, here is the price a fact too. You can get 41 II at a cheaper rate which won’t make you regret it.
So, consider your budget while choosing the speaker for you between RB-41 II VS RB-51 II.
RB-61 II VS RB-81 II
The same thing goes for these two speakers as they also have the same design, tweeter, or woofer.
But we cannot say RB-81 II is the only winner here as RB-61 II have almost close features and rates.
Starting with the woofer size, 6.5’’ is common in most high-quality speakers since it has the capability of producing big sound. But who does not want to get bigger than this? This is what exactly RB-81 II is providing with an 8’’ woofer. This has shocked many as 8’’ woofer is rare.
Then RB-81 II is a step ahead with power and sensitivity. If you want a blast in your home then 97 dB is perfect. Though over 90 dB is enough for getting a breathtaking loudness. Regarding this, both speakers are much better than other speakers.
However, as these two speakers are giving huge effort, they need enough power. According to the performance, both have their perfect power handling capacity.
Summarizing again, both are great in their own unique way. It depends on which one whether RB-61 II VS RB-81 II; you want to have.
