GRUNDIG 1951 10" Coaxial Speakers 22.5cm Alnico + Electrostatic Tweeter RARE

Description

For sale is a rare pair of GRUNDIG coaxial loudspeakers ( 1951) with a 22.5 cm driver diameter, featuring an integrated electrostatic tweeter mounted in front. These sophisticated, high-technology drivers originate from the GRUNDIG 5005W – a top-tier German tube radio of the early 1950s and one of the most advanced and expensive receivers of its time( With 2 x EL41 tubes in. Push-pull mode ) . Accordingly, the speaker design reflects a no-compromise engineering approach. The combination of a dynamic full range driver with an Alnico magnet and an electrostatic tweeter is sonically exceptional: the speaker delivers a natural, warm, and finely textured midrange and bass response with the characteristic Alnico tonal signature, while the electrostatic tweeter, due to its low moving mass, provides outstanding highest -frequency resolution. The result is an airy, highly detailed sound with excellent imaging and transient response. The electrostatic element (each with 3 nF capacitance) reacts extremely fast and integrates ideally within the coaxial configuration, effectively acting as a near point source. This ensures a coherent presentation without the typical phase and timing issues of conventional multi-way designs. Important technical note: The electrostatic tweeters do not exhibit a conventional ohmic resistance; instead, they present a capacitive load. Therefore, they must be operated with an appropriate series protection resistor to ensure safe operation and to prevent damage.
