What makes a truly good speaker? As is well known, this is a topic of frequent and extensive discussion in the hi-fi community. Tastes vary—and yet there are clear characteristics that distinguish high-quality speakers.
I often hear people say things like, “This or that speaker sounds just like being at a live concert!”
But that’s exactly where the problem begins. Because, to be honest, many concerts don’t sound particularly good. Depending on the venue, acoustics, sound system, and listening position, the sound can actually be pretty bad. Open-air events are especially challenging—there, you’re often faced with very subpar sound quality.
One exception is small, unamplified acoustic concerts: a solo artist, a jazz trio, or a classical ensemble performing in a relatively small venue. In such settings, you experience the voices and instruments in a direct, natural, and authentic way.
A good speaker should reproduce music exactly as the sound engineer intended
With this in mind, the goal can only be one thing: a speaker (and the entire system!) should reproduce a recording as closely as possible to how the sound engineer intended and heard it. Because we must be aware of one thing: what was lost during the recording is very difficult to recover—even with the best high-end equipment. Ultimately, it is the microphones and the loudspeakers that have the greatest influence on the overall quality of the recording and playback process
Any speaker design can sound good
When properly tuned, any speaker design can sound great—whether it’s silk, aluminum, or beryllium domes, horns with compression drivers, ribbon or film tweeters, 2-, 3-, or 4-way systems, sealed, bass-reflex, or passive-driver bass systems, transmission lines, bass horns, or open baffles. Or magnetostats and electrostats. I’ve had the opportunity to confirm this through numerous listening tests. Nevertheless, there are clear indicators as to whether a loudspeaker—regardless of its design—is in the top league or not.
So what exactly makes a speaker sound really good?
1. It immediately grabs your attention and draws you into the music.
After just a few bars, you find yourself thinking: Wow! That’s really cool. “Good definition” is perhaps the most accurate and commonly used term to describe this quality. The sound is homogeneous, lively, crystal-clear, and never intrusive or dissonant.
2. He sets up a clearly defined stage with a distinct focal point in front of you.
There’s much more to it than just two speakers: a large, clearly defined soundstage unfolds before you. If the vocals or lead instrument were centered during recording or mixing, they now stand between the two speakers as if carved in stone. It literally floats in the room. The two sound sources recede into the background—the musical action unfolds transparently and in layered depth right in front of you.
3. He captures voices so authentically and naturally that you fall in love with the singer
The human voice is something so wonderful, with subtle nuances that are so much more than just sounds. It can convey emotions, moods, and entire worldviews. With a good speaker, you’re right there in the moment. You’ll discover details you’ve never heard before. You’ll be able to pick out the finest nuances of the vocal timbre and be swept away into the artist’s world—as if it’s happening right now and you’re standing right there beside them.
4. He plays with such speed and energy that you can't help but keep listening
It’s the tiny micro-details that make a recording truly interesting. What sounded rather dull and made you want to change the channel on lesser speakers suddenly becomes fascinating. You discover and understand what the artist intended to convey and how the sound engineer heard it. The magic of music comes to life. The notes are delivered without delay—the soundscape thrives on an airy lightness.
5. The bass is authentic and deep, without any artificial boost
Authentic bass extends below 40 Hz without any artificial enhancement. Most speakers can’t really do that, so they compensate by boosting the upper bass. The result is a somewhat muddy bass that can still be satisfying if you’ve never heard anything else. Anyone who has ever heard a clear, well-defined low bass knows what I mean. Of course—the room and the setup play a huge role in bass performance. For me, it’s important that a speaker handles the most common room setups well.
6. It still sounds rich in detail even at low volumes
When do you ever really crank up the volume? More often than not, you listen at a lower volume late into the evening. Have you noticed that too? Your system sounds best when there’s less traffic on the power grid in the evening. That makes it even more enjoyable. And a good speaker will treat you to a rich, captivating level of detail even at low volumes.
7. He doesn't get on your nerves, even after hours together
Have you ever had that experience? A speaker literally jumps out at you, and you’re thrilled. After a while, though, you realize it’s too much of a good thing. It starts to feel intrusive and almost unpleasant. A good speaker doesn’t tire you out, even after many hours. On the contrary—it draws you so deeply into the action that you actually don’t want to stop listening! That’s true long-term appeal.
Don't be too analytical when evaluating it!
For me, it’s important not to approach evaluation in an overly analytical way. Music is a very subjective experience. Assessing the quality of its reproduction can therefore only be a subjective, holistic, and largely intuitive process. Even measurement data can only capture this very incompletely. It is an extremely complex interplay of numerous components. The design of the enclosure, the drivers, the bass tuning, the internal wiring, the subtle tuning of the crossover. A good loudspeaker is the successful blend of all these elements. For this reason alone, they are rather rare to find.
