Gladen is gradually unveiling its new products for the coming years and, after the Zeta, Sigma and Gamma lines, now presents the more affordable Beta series. In the German manufacturer’s range it fills the gap between the discontinued M-Line and the popular RS series, while the more technically advanced Gamma aims even higher. Beta therefore represents a more accessible entry into Gladen’s high-quality car audio and focuses primarily on traditional materials, a natural sound signature and high efficiency. Let’s introduce its main characteristics, available models and the differences compared to the higher Gamma series.
Beta and its position in Gladen's portfolio
Gladen introduced two new speaker series at almost the same time – Gamma and Beta. Although their prices may seem relatively close at first glance, each occupies a different position in the brand’s lineup. The more technically advanced series Gamma represents the direct successor to the very popular RS range and pushes its sonic capabilities significantly further. The new Beta, on the other hand, is positioned a bit lower and fills the gap between the outgoing entry-level M-Line and Gladen’s higher models. This is precisely the space the brand has long occupied to a significant extent. The best-selling M-Line clearly provided an affordable entry into Gladen’s range, while RS belonged to the more advanced speakers intended even for demanding installations. Beta creates a new middle step between them for customers who want significantly better sound than the basic models but do not require the latest technologies, higher power and the technically more precise character of the Gamma series. With this move Gladen clarifies its entire portfolio and offers customers finer gradation between the series. Beta therefore does not take on the role of a direct RS successor but expands the offering with a separate category that was previously missing between the basic and higher models.
And which products are we talking about?
Beta currently includes only four models. Available are component and coaxial speakers with diameters of 165 and 130 mm — the most requested sizes for standard car installations. Whether Gladen will expand the lineup with additional sizes in the future remains to be seen.
- Gladen Beta 165.2 - component speakers, Ø 165 / 25 mm, 65 W RMS, 3 Ω, 93.5 dB.
- Gladen Beta 130.2 - component speakers, Ø 130 / 25 mm, 45 W RMS, 3 Ω, 94.8 dB.
- Gladen Beta 165-X - coaxial speakers, Ø 165 / 20 mm, 60 W RMS, 3 Ω, 94 dB.
- Gladen Beta 130-X - coaxial speakers, Ø 130 / 20 mm, 40 W RMS, 3 Ω, 90.8 dB.
What to expect from the sound?
The Beta series represents a sort of gateway into the world of Gladen’s quality car audio. It was designed to offer a very good balance between sound quality, efficiency, price and ease of installation into modern cars. The basis of all models is a balanced tuning focused on natural music reproduction, which is reflected in the materials used, primarily paper and silk. The speakers deliver clear and well-defined midrange, smooth highs and a solid, controlled bass foundation. Their sound character is neither overly showy nor aggressive, which keeps it pleasant even during long listening sessions and makes it work across a wide range of musical genres.
An important feature of the Beta series is its high efficiency. The speakers were engineered to work very well when connected directly to factory or common aftermarket head units, while also being able to take advantage of higher power from an external amplifier. The numbers speak for themselves. The Beta 165.2 component set offers sensitivity above 93 dB and an impedance of 3 Ω. Such values are usually paid for with a higher resonant frequency of the midwoofer and correspondingly weaker reproduction of the lowest frequencies. However, Gladen’s engineers managed to achieve a resonant frequency of 71 Hz, which is a very good result given the high sensitivity. Beta speakers are therefore suitable both for a simple replacement of the original factory sound system and for more elaborate installations with an external amplifier, without unnecessary compromises in sound quality.
Below you will find more details about the materials used, which have a direct impact on the resulting sound and overall concept of the Beta series.
Traditional paper midbass cone
The Gladen Beta midbass speakers use a classic paper cone. Although paper can seem plain compared to modern composite materials, it remains one of the most respected materials in speaker construction. It offers low mass, very good internal damping and, above all, a natural rendering of mid frequencies without unwanted coloration. The paper cone significantly contributes to the characteristic presentation of the Beta series. Vocals and musical instruments sound natural and intelligible, while lower frequencies remain firm and well controlled. The construction is complemented by a durable Nomex spider that ensures long-term mechanical stability, and a 25 mm KSV voice coil capable of maintaining consistent parameters even under higher load. A soft dust cap helps preserve a smooth and natural midrange character.
Silk dome tweeter
Both the component systems and the coaxial Beta speakers are equipped with a silk dome tweeter. It delivers detailed, delicate and refined high-frequency reproduction while providing a pleasantly warm tonal character that does not tire even at higher volumes or during extended listening. The tweeter uses its own plastic housing with an acoustically optimized rear chamber. This helps better control the dome’s movement, smooth the frequency response and enable a seamless transition to the midbass driver. The result is an open soundstage, good instrument localization and a natural spatial rendition of the music. An important aspect of the series is that Gladen preserved the same design philosophy for the tweeter in both component and coaxial models. The difference lies mainly in dome size: component systems use a 25 mm dome, while coaxial models use a 20 mm dome. This ensures that individual speakers across the range maintain a similar sonic character.
Well-designed frequency crossover
The component systems also include an external frequency crossover with a 12 dB per octave slope and a crossover frequency of 3.5 kHz. Its tuning ensures a smooth transition between the midbass and tweeter without a noticeably audible gap between the bands. The crossover is also equipped with a two-step tweeter level adjustment. The character of the high frequencies can thus be adapted to the specific speaker placement in the vehicle, the interior’s acoustic conditions and the listener’s personal preferences.
Focus on easy installation
When developing the new Beta series, Gladen also took into account the specific requirements of modern cars and adapted the entire design for easy integration into factory locations. The speakers’ power, impedance and high sensitivity are tuned to work very well even with weaker factory head units, while at the same time offering enough potential when connected to an external amplifier. Another big advantage is the compact dimensions of the components. Thanks to their small bodies, the crossovers can be easily placed practically anywhere in the vehicle interior. The midbass speakers have a reasonable mounting depth and therefore should not cause problems even in space-limited doors. Particular attention deserves the very compact tweeter, which, despite retaining a 25 mm silk dome, can be mounted in most original locations. The component system package also includes housings for surface and flush mounting of the tweeters as well as mounting adapters intended for hard-to-reach places. The Beta series is thus prepared not only in terms of sound but also for quick, clean and technically undemanding installation into a wide range of modern cars.
In conclusion: who is the Beta series intended for?
Gladen Beta is an ideal choice for customers who want to move beyond basic speakers. It offers a natural and balanced sound, high efficiency and a design maximally tailored for easy installation into modern cars. This makes it suitable both for a simple upgrade of a factory sound system and for higher-quality installations with an external amplifier. In Gladen’s portfolio Beta fills an important space between the basic models and the higher series. For more demanding listeners who require newer technologies, higher power, more accurate reproduction and a wider selection of models, the higher Gamma series remains the intended choice. Beta, on the other hand, bets on affordability, versatility and a proven sonic approach, which allows it to appeal to a very broad group of customers.
