Klipsch Promedia 2.1 vs Logitech Z623 | Which one is the best? 2023

Klipsch and Logitech lie in the category of re-owned audio companies that are in the market since a long time. Both have produced speaker systems that have competed against each other. The Klipsch Promedia 2.1 and Logitech Z623 are both popular 2.1 speaker systems known for their audio performance.

Let’s figure out the main differences between these speakers.

Klipsch Promedia 2.1 vs. Logitech Z623


When we go any further, it’s important to note that these speakers aren’t brand new, both have old looks, however, the most important thing is the sound quality. It’s tough to pinpoint the release dates, but the Logitech Z623 would be turning ten shortly, if it hasn’t already, while the Klipsch ProMedia 2.1 is already more than a decade and a quarter old. These speakers are of genuine quality, as seen by their continued


Most significantly, each of these speakers is THX-certified, which guarantees a high sound quality. The THX requirements are stringent and not cheap.

Although there are loudspeakers that technically meet this certification, Logitech and Klipsch went above and beyond to guarantee that both are 2.1 stereo sounds are up to par.

2.1 speakers may only receive the lowest level of certification, which is understandable given that filmmakers aim for a full surround sound immersion while filming. However, this still implies that these two speakers will be excellent for PC use and audiophile speakers.


‘Wait a minute!’ you might be thinking. Isn’t this a pair of wired PC speakers? The THX accreditation is excellent, but are we going to go through the hassle of unplugging them from the computer and rewiring all the wires only to put them on the TV with one movie date?

Yes, both the Z623 and the ProMedia 2.1 are connected speakers, but the designers made every effort to integrate as many features as possible. For example, on the satellites, each of these speakers includes headphone connectors and independent volume and bass dials.


The sound quality provided by each of these speakers is the essential element in their continued popularity. We’ll say that none of these speakers sounded any worse than most modern speakers or many more expensive versions. Either way, you can’t go wrong.

Rather than writing a thorough evaluation, we’ll focus on areas where each of these speakers shines above the others.

The Logitech Z623 comes first. It is one of the two participants that will appeal to gamers the most because of its three-dimensional sounds.

What’s the Difference?

The following are the primary differences between the KlipschPromedia 2.1 and the Logitech z623:

  • The KlipschPromedia 2.1 doesn’t support RCA input, although the Logitech z623 does.
  • Compared to the Promedia 2.1, the Logitech z623 is around $30 less costly.
  • The Logitech z623 offers a slightly more extensive frequency reaction range of up to 35Hz, while the Promedia 2.1 has a frequency spectrum of 31Hz.
  • Compared to the Logitech z623, the KlipschPromedia 2.1 offers a more excellent bass rebound.

Klipsch Promedia 2.1 vs Logitech Z623: Reviews

KlipschProMedia 2.1 THX Certified

The KlipschPromedia system, while somewhat more expensive, proves to be a terrific all-in-one solution at a reasonable price. Klipsch’s expertise in high-end speakers shows a little less brightly, but it still shines brightly.


  • Whereas this set is simple, it comes with enough functionality to justify the price. The absence of tuning knobs is frustrating, but these speakers require minimal fine adjustment for the price.
  • The THX accreditation is a noteworthy feature. Lucasfilm Ltd., the firm behind Star Wars and Indiana Jones, established the THX standard. To obtain certification, items must first pass quality and performance testing.
  • There isn’t a remote control here, which would be wonderful to see. On the other hand, controls are located on the front of the speaker, allowing easy access.
  • If you require a different location, the admin console on the bottom of the speaker may pull out. Sitting directly beneath the speaker saves desk space, but it’s an alternative if you need it.
  • Klipsch used a 22 gauge speaker wire instead of a 3.5mm connector on the sub. While this won’t improve the quality, it will allow you to cut the wire to your specifications without having to solder it.


Klipschrecognizes for its stunning-looking speakers and its excellent sounding speakers. Even though this modest set can’t compete with the larger ones in the range, Klipsch has managed to turn a dull pair of speakers into something special.

The speakers’ fronts are flat black, yet they still have the distinctive Klipsch flare that makes them stand out. In this scenario, the cone is somewhat yellow. The color won’t detract from the overall design, and you won’t notice it from afar, but it offers just enough aesthetic up close to make the set seem excellent.

Aesthetic Appeal

Even with all that, the music is the main attraction with this pair of speakers. Klipsch’s reputation for producing high-quality speakers is carried over into this tiny package that is a delight to listen to.

The downforce subwoofer, which measures 6 12 inches in diameter, is extraordinary. It’s not the greatest woofer, but it’s rather good for the price. The volume of the loudspeakers can be changed individually via the command pod, allowing you to dial in the exact amount of low-end.

  • The highly efficient architecture of the KlipschProMedia 2.1
  • More sound is reproduced by the KlipschProMedia 2.1
  • THX Certified Speaker System thanks to its highly efficient design.
  • Play setup and handy 260 watts of peak power
  • The input of 3.5 millimeters
  • The subwoofer began to cut in and out of the picture.

Logitech Z623 400 

Logitech is a behemoth in computer accessories, producing many models, including the z623. This set is towards the higher end of the range, ranging from the budget-friendly Z313 to the top-of-the-line Z625. But, when $100 is deemed high-end, can much be expected?


  • The z623 set is pretty similar to the Promedia 2.1 set in terms of features. You’ll find almost everything you saw before, with minor exceptions.
  • Of course, THX accreditation is there, as seen by the THX emblem displayed beside each satellite, because the speakers handle conversation and noise levels. At the same time, the sub delivers all of the earth-shattering bass THX tests to home theatre requirements.
  • The subwoofer reaches down to 20Hz at -6dB, following THX standards. The mismatch is because this does not fall inside the conventional -3dB frequency response criteria. Feel sure the sub does touch 20Hz at -6dB.
  • The controls locate on the front of the speaker; however, unlike the Klipsch set, they are not detachable. It’s hardly a deal-breaker, but it’s frustrating given Klipsch’s ability to develop such a slight but significant improvement.
  • You do, however, have the option of using Bluetooth, much like the Klipsch set. It costs $20 more than the Klipsch, but it’s available separately. However, there are certain advantages and disadvantages to this.

Logitech’s design

In my opinion, it isn’t the finest. While we love the metal grilles and their safety, the aesthetic isn’t as appealing as the Klipsch scenario.

The satellites are a tad smaller, but the subwoofer is giant. It is perplexing to me. With smaller and smaller computers, desk space is abundant, whereas a large sub might pose problems on the floor.

Aesthetic Appeal

It is where Klipsch and Logitech genuinely differ. While the z623 system isn’t awful, it can’t compete with the audio titans.

The subwoofer response exemplifies this. The bass isn’t as distinct and tight as it was in the last set. Instead, the reduction comes through, but it’s too murky. It will rock your floor, not in a tight hit, but a chaos of bass.

  • THX-certified 2.1 sound system
  • RCA and 3.5-millimeter inputs bring your music to life.
  • There are two satellite speakers as well as a potent subwoofer.
  • Compatible with any device that has a headphone jack.
  • Sounds with a high pitch

Final Verdict

Finding a good pair of speakers for your PC that aren’t too expensive might be difficult. Klipsch and Logitech, on the other hand, provide consumer-friendly choices at a reasonable price. The Klipsch set is excellent for folks who require high-quality audio. While the price is significantly more, the precise bass performance and clear satellites readily justify it.

However, compared to the price, the Logitech set isn’t awful. If you don’t mind a little looser low-end and a mediocre aesthetic, the extra $40 off is well worth it.
