What we don’t like

As always, Klipsch never fails to perform when it comes to the sound quality of their speakers. Being a front-runner in the audio equipment industry, they make sure that all their models, regardless of their price, are the best in their respective price range.

The Klipsch RP-150M bookshelf speaker is one such model, which, as expected, delivers a phenomenal sound quality. Find out more in this Klipsch RP-150M review.


Weighing, 14.7lbs these speakers are built solid. One of the most important aspects in this Klipsch reference premiere RP 150M review is its design as it has changed significantly from its predecessor.

With a new-brushed metal look and the removal of the ABS baffle, it looks aesthetically much pleasing than its predecessor. Furthermore, it now sits atop a plinth, which is an interesting innovation for the speaker.

The Cerametallic woofer is not a new feature as it has been a standard in the reference series since it was launched. As far as the tractrix horn is concerned, there have been modifications made to it.

With a wider dispersion pattern and a design that produces flatter response at high frequencies, the tractrix horn increases directivity.


The sole reason behind the fantastic sound quality that these Klipsch bookshelf speakers produce is its features. Let’s shed light on some of these features in this section of our Klipsch bookshelf speaker reviews.

LTS Titanium Tweeter

Also known as the Linear Travel Suspension tweeter, this is one of the most important features of the Klipsch reference RP 150M.

Equipped with a modified tractrix horn with a vertical coverage of 90×90, this tweeter is what improves the overall sound performance. This is done by minimizing distortion and adding a lot of detail to the sounds to make it more appealing to your ears.

Cerametallic Woofers

Unlike the IMG woofers that several Klipsch models are equipped with, the reference series have Cerametallic woofers as the standard.

It is an aluminum cone sandwiched between two layers of ceramic which has been anodized to the front and back surfaces of the cone.

The 5.25-inch cerametallic woofers of the Klipsch bookshelf speakers RP-150M add to the already lightweight design of the speaker as well as boost the overall rigidity of the speaker.

The main advantage of these woofers is the minimal cone breakup and distortion that they offer. One of the primary reasons behind the impeccable sound quality of these speakers is the cerametallic woofers.

New Tractrix Port

One new addition to this model is going to be mentioned in all Klipsch RP-150M reviews that you find. This is the new and improved tractrix port.

Using tractrix geometry in the perfect fashion, this port ensures the most efficient and quick air transfer from the cabinet for the most manifest low-frequency response.

Magnetic Removable Grille

To allow for easily accessible transitions from loud and powerful to soft and mellow this removable grille attaches magnetically. Although it doesn’t seem like too much, it allows for a much easier process of detaching and reattaching the grille.


As far as the pricing is concerned, the RP-150M can be considered affordable as well as expensive. If you view it from the perspective of what gives you the best value of money and the most features in the least amount of price, then this speaker will look affordable to you.

Ranging from $350-450 is a very affordable model, given its sound quality. On the other hand, it will not seem like an affordable model to opt for since you can find multiple bookshelf speakers under $500 that are cheaper than this. This is why for hardcore audiophiles, this might be a plausible option, but for people on a budget, it might not be.


  • It is also an extremely sturdy and durable speaker, which is why you don’t have to worry about it breaking easily.
  • If you are a bass lover, then it offers a very tight and punchy bass which will please your auditory senses.
  • It is styled with an MDF cabinet with brushed polymer and veneer baffle finish to make it stand out.
  • One of the most significant advantages of Klipsch reference series is its versatility when it comes to aesthetic compatibility with almost any room.


  • As seen from its weight, it is not very light and definitely not small which makes its placement and mobility difficult.
  • Expensive and not affordable when compared to other bookshelf speakers under $500.

Overall when you compare this speaker to its predecessors, you will see a leap from mediocrity to perfection. Klipsch has gone all out with the improvements made to this model in the reference series which we have highlighted in this Klipsch RP-150M review.

Klipsch has excellently targeted the flaws in the previous models; for instance, the low coverage of the tweeter and fixed them. In the process of fixing these flaws, it has drastically improved the performance of the speakers, which has made them a front-runner for audiophiles.

Apart from the fantastic sound quality these speakers now flaunt, their aesthetic characteristics have also been boosted. The previous model was aesthetically very displeasing. On the other hand, although big and heavy, the RP-150M has good aesthetic compatibility with different decors due to its design and different color schemes available in the market.
