Our summary
Product Strengths
- The Acapella Apollon's plasma tweeter produces extended, pure, and dynamic sound, and the speakers have good resolution
- Able to reproduce the subtleties of a recording with realistic reproduction of the dynamics of very low-level information
- Use a sealed bass alignment, meaning the distance from the back wall is not quite as critical as it would be with a ported speaker
- Efficient and work well with smallish tube amps
Product Considerations
- The Acapella Apollon speakers are large and probably require a dedicated listening room
- Heavy and require on-site assembly—the total shipping weight is 1,643 pounds
- Require a break-in period of 30 to 90 days
- One reviewer had initial issues with the tweeter malfunctioning, requiring tube replacements
Comparisons (according to reviewers)
- Vs Acapella Campanile: Look like bigger Campaniles with bigger cabinet and bigger horn, better crossover, better drivers, more expensive
- Vs Acapella Triolon: More resolution and integrated sound, but less dynamic in the mids
- Vs Marten Supremes: More open, dynamic, and musical, but ultimately has less resolution
- Vs Avalon Eidolons: Can go right up against the front wall unlike the Avalon Eidolons, which were further out in the room
Takeaway: The Acapella Apollon speakers are high-performing speakers able to reproduce subtle details, work with tube amps, and do not need a lot of space from the back wall. With the available space and budget, the Acapella Apollon could be a good choice.

Our take on the brand
Thoughts are born, ideas are thought through to the end and we take our know-how to the extreme. We have developed the most innovative technologies, increased efficiency and raised the level of performance. But we have not done all this to focus on knowledge, skills and pioneering spirit, but rather to make that one special feeling even more tangible: the absolute joy of listening to music.
The Sphäron Excalibur is the largest loudspeaker system ever built by Acapella. It sets the standard worldwide and goes far beyond in terms of precision, plasticity and dynamics. With the 2.30 meter high system and 600 kilograms weight per loudspeaker, a superlative has been created in which technology becomes pure emotion.
Four 18-inch bass speakers are installed in the room-high four-way loudspeaker, the world-famous ion tweeter handles the high tones and the two classic spherical horns on the sword side of the Sphäron Excalibur complement the mid-bass range. With just 1 watt of input power, the Sphäron Excalibur demonstrates a power and speed that drives the adrenaline level up.
With a Sphäron Excalibur, we promise to always go one step further, to make what is technically possible possible in an inimitable way. This means that extraordinary loudspeakers are created for extraordinary people and sensual experiences of a very special kind are guaranteed.

Our take on the brand
Which moments remain in our memories? Those in which we feel free. In which we are inspired to do something new. In which every detail is perfect. Moments in which we feel something with all our senses, which touch us with their pure power. Moments in which time seems to stand still because we encounter something extraordinary like the Triolon Excalibur MK-V.
The Triolon Excalibur MK V is a parallel to the Sphäron Excalibur and is characterized in all essential aspects by the same superiority and effortlessness in music transmission. The slightly smaller size allows the use of this horn system in rooms from 25 m². In its 5th generation with over 25 years of development, the Triolon Excalibur MK V has matured into a loudspeaker of incomparable quality. It was created so that every moment can be spent intensively on something meaningful and beautiful: listening to music.
The Triolon Excalibur MK V is the perfect fusion of the highest quality and maximum listening pleasure. At the heart of the system is the ion tweeter, around which the large spherical horns and basses are arranged. The 4-way system has a time response that is similar to that of a point source speaker thanks to its intelligent crossover design and construction. In combination with the size of the system, the Triolon Excalibur MK V fills the room with music of the highest dynamics and clarity. And it does this with small amplifier outputs starting at 15 watts.
The Triolon Excalibur MK V conveys the charm of the extraordinary. Selected materials and craftsmanship perfect this system and you get a loudspeaker of special value. It is one of those things in life that you have to experience for yourself.
