- 2-way coaxial system with car-specific upgrade speakers for BMW
- 4” / 100 mm woofer and ¾” / 20 mm tweeter for the original mounting positions
The MS 4X-BMW.2 two-way coax-system with vehicle specific baskets and integrated crossover is the perfect sound upgrade for BMW-models with standard OEM speakers without separate tweeters. The system’s 4“ midranges and 20 mm tweeters deliver musical brilliance and authenticity which is usually lacking in original BMW systems. The speakers fit perfectly into the original mounting holes in front- and rear doors of several BMW models.
The APBMW X coaxials have been designed for BMW-MINI models that do not allow the installation of a two-way system on the front or the upgrade of the rear system.
The 100 mm (4″) APBMW X4E, with basket and fixing screws dedicated to the specific car model, feature a water-repellent pressed-paper cone for natural and color-free mid-range frequencies.
The 20 mm coil and Tetolon dome tweeter, a material boasting lightness and damping properties, offers optimized dispersion features for OEM placement, elevating the sound stage to a realistic level.
These reference speakers in our C-series raise the bar to a new level of fantastic sound quality. The legendary sisal woofer cones are equipped with an additional structural damping layer made of an elastomer, which again improves the acoustic properties of the driver. The tweeter enclosure also underwent a complete overhaul. Anyone who wants to operate these loudspeakers as fully active speakers (e.g. using our new digital signal processors) can put together the system of their choice by combining the individual components.

Once again the new E-series loudspeakers (formerly known as “ESPRIT”) have set a new marker in the industry in terms of outstanding workmanship and acoustical performance.
Intelligent construction combined with selected materials guarantee an exceptional listening experiences and maximum reliability. The woofer cones of this loudspeaker series are made from woven fiberglass. The structure provides essential stiffness with a high inner damping, thus no disturbing resonances. The result: powerful and clear low frequency reproduction.
A stiff basket with additional ventilation holes and our proprietary HELIX design assure ultimate voice coil cooling and high power handling. Their sound characteristics and reliability are as a result from our specially shaped butyl surrounds.
Extensive fine-tuning of the crossover brings with it a precise splitting of the frequency band. It ensures a flat frequency response and unprecedented harmonic sound. The tweeter has also been upgraded. Its splendid high frequency resolution will guarantee brilliant and well balanced highs.
The classic design underlines the high-end aspect of this speaker series.
