Review: Teufel Theater 500, Three-Way Floorstanding Speakers

Today I have something big in my hands—and not just because of its size. These are the Teufel Theater 500 floorstanding speakers, a pair that promises high-fidelity sound at a very reasonable price. Before I dive in, I want to thank the folks at Teufel for sending me a pair of these speakers so I can tell you in great detail what I thought of them.

For those of you who aren’t very familiar with the subject, Teufel is a German brand that has earned a solid reputation for offering audio products with an excellent value for the price. These Theater 500s are three-way floorstanding speakers. And what does “three-way” mean? Well, it’s as if there were three specialists inside each speaker: one for the bass (explosions in movies, bass in music), another for the midrange (voices, for example), and a third for the treble (cymbals on the drums, the sound of breaking glass). This division of labor allows each sound to be reproduced more clearly and precisely.

Based on their specs and features, these speakers seem to offer high-quality sound for both watching movies and listening to music, and, of course, I’ll give you my honest opinion on whether or not they deserve a spot in your living room. Let’s get to it.

Technical Specifications

When I received the Teufel Theater 500, the first thing that caught my attention was the size of the boxes. Each speaker comes in its own cardboard box, which is quite large and very sturdy. On the outside of the boxes, aside from the typical shipping labels, the Teufel logo is clearly visible, along with a “FRAGILE” warning to ensure that carriers handle the packages with the care that equipment of this caliber deserves.

When we opened the boxes, we found that each speaker tower was perfectly protected. They are nestled in thick white foam inserts that keep them completely secure, and they’re also wrapped in a fabric cover to prevent any scratches during shipping.

Once everything is out, we see that the content is just what’s needed:

• The two speaker towers, one for each speaker cabinet.
• 8 protective covers to cover the 4 speakers on each tower.
• A user manual containing the technical description.
• And two small bags, each containing four adhesive rubber feet—a very practical feature for attaching to the base to protect both the speaker and the floor from potential scratches or moisture.

Why doesn’t it come with any cables, not even a power cord? This is completely normal for passive speakers, which means they don’t have their own built-in amplifier, so they need to be connected to an external amplifier or an AV (Audio/Video) receiver to work. This device, using speaker cables, will send the amplified audio signal to the speakers, so it’s important that both the amplifier and the AV receiver are high-quality to ensure you can get the most out of these speakers.

Teufel Theater 500 Tower Speakers: Design and Features

When you stand in front of the Teufel Theater 500 speakers, the first thing you notice is their imposing presence. They feature a sleek design with very straight lines and a black MDF finish that blends seamlessly into almost any decor. They aren’t exactly small, standing over a meter tall, 20 cm wide, and nearly 30 cm deep.

The most striking feature on the front panel is its four-speaker configuration. At the top, dominating the design, is the tweeter (which handles high-frequency sounds), which is slightly recessed and surrounded by a small horn or waveguide. Just below that is the midrange speaker, followed by two identical woofers for the bass. All of them feature a Kevlar cone—a lightweight, rigid material—and are framed by a gray ring that breaks up the monotony of the black a bit. The screws that hold them in place are visible, giving it a slightly more industrial look. If you prefer a sleeker look or have curious kids at home, each speaker comes with its own circular, magnetized fabric grille to protect it from both those curious hands and dust.

One particularly unique design detail is the base. The main speaker enclosure is raised on feet, leaving a gap underneath. This isn’t just an aesthetic choice; it serves one of the speaker’s key features: the downfiring bass reflex system. Basically, the port through which the air exits points toward the floor to boost the bass, dispersing the sound in a 360-degree pattern. The big advantage of this is that it gives us much more freedom to position the speakers, allowing us to place them closer to the wall without the bass getting “muddy.” Additionally, the port is oversized to prevent turbulence when the volume is turned up.

On the back panel, everything is very clean, with the only notable feature being a dual set of connection terminals. This allows for bi-wiring or bi-amping, which simply means using two cables or two amplifiers per speaker to handle the frequencies separately and, in theory, get even more out of them.

However, what’s truly interesting is inside. This is a three-way system, which is uncommon in speakers in this price range. As I mentioned in the introduction, this means the sound is split into three paths: the two 160-mm woofers are dedicated exclusively to bass sounds, the 160-mm midrange driver handles the frequencies where vocals and most instruments reside, and the 25-mm tweeter handles the high frequencies.

But Teufel didn’t stop there; it has added several technologies to fine-tune the sound. One of these is Time Alignment, which physically positions the tweeter behind the rest of the drivers, ensuring that sound across all frequencies reaches our ears simultaneously, resulting in a more precise and detailed stereo image. Another technology is the Constant Directivity Concept, which, thanks to the waveguide surrounding the tweeter, ensures that sound is dispersed widely and evenly throughout the room. Furthermore, this means you don’t have to sit in a specific spot to enjoy great sound; the quality remains consistent from various listening positions.

To top it off, hidden inside the enclosure is a damping chamber that works on the principle of the Helmholtz resonator (a very technical name for something that aims to eliminate unwanted vibrations and internal resonances). By controlling these “standing waves” so precisely, the bass becomes cleaner and more powerful without the need for as much internal damping, which can sometimes “siphon off” some of the sound energy.

Exams and Final Evaluation

After several weeks of using the Teufel Theater 500 as my main system, I put them to the test with different styles of music, a few movie scenes, and a couple of video games to see how they perform. And I have to say that the result was more balanced than I expected.

For the bass test, I started with “Angel” by Massive Attack. That bass kick really made its presence felt, but without sounding out of control—deep, tight bass, so precise that there’s barely a trace of excess vibration. I wasn’t expecting this kind of performance in this price range (900 euros, though currently on sale for 600 euros). I then switched to “Fast Car” by Tracy Chapman to focus on the midrange. Chapman’s voice came through clear and warm, with every nuance defined, and the guitar strums were agile without losing body. The transition between bass and midrange is practically imperceptible—something uncommon in speakers in this category.

When I moved on to the high frequencies with Queen’s “Bohemian Rhapsody,” I noticed that the cymbals and backing vocals remain clear and well-separated, although it lacks that exquisite nuance found in much higher-end models. If you mainly listen to high-energy genres—rock, electronic, hip-hop, or dub—you won’t miss any additional detail.

The stereo image is another plus. With Pink Floyd’s “Money,” the soundscape opened up completely: I could easily make out the tambourine on the right and the snare drum effects on the left, while the bass line remained firmly centered.

As for a movie session featuring the opening scene of *The Dark Knight*, the gunshots boomed with force, and the whispers in the soundtrack maintained the tension without being drowned out. I didn’t miss having an external subwoofer; the bass from the Theater 500’s four woofers offers more than enough punch to immerse you in the action—however, if you’re someone who can’t live without dedicated bass, you can always add the Teufel T 10, another beast of a subwoofer. The same goes for the video game Cyberpunk 2077: the sound of car engines and dialogue come to life without straining the tweeter, and the atmosphere gains an extra layer of realism. For those who switch between gaming and home theater, these speakers are an excellent choice.

In conclusion, after using them for several weeks, I can say that the Teufel Theater 500s are powerful floorstanding speakers characterized, above all, by punchy, well-controlled bass, accompanied by clear and natural mids. Their dynamic range makes you want to turn up the volume, and the stereo image feels wide and stable. The design is unobtrusive yet sturdy, and the bottom-firing bass reflex port makes it easy to place them close to a wall without sacrificing performance.

Priced at 900€, although you can currently find them for as low as 600 euros on Teufel’s official website, it’s hard to find a competitor that offers such a well-rounded sound. For all these reasons, I’m awarding it our “Recommended Product” badge and the prize for Best Value.
