RAAL 70-20XR Flatfoil Ribbon Tweeter

Raal is proud to present the pinnacle of contemporary true ribbon design. It defines new limits to a known, old, concept. Superior in sound quality and reliability, it deals with every task by incomparable dominance. The uncompressed reproduction of the signal dynamics, is what makes it better than any corrugated true ribbon design and, still, it has only 4 micrometer aluminium foil. New ideas, science, art and experience, brought together. Painstakingly bred by connoisseurs for their own kind.

Product description

World’s smallest form factor for a true ribbon of just 1.8 kHz cutoff frequency, reliable, able to handle a lot of power, sounding like it doesn’t exist... All that by using only one series capacitor as a complete L-R 4th order crossover at 1.8k, combining acoustical and electrical slopes, with minimum of added passive crossover components. Featuring three transformer taps for resistorless sensitivity adjustment, ribbon replacement kits, custom front plates, copper soldering posts. All of it, makes it perfect for reaching new limits in high-end home stereo or multichannel and near-to-mid field studio monitoring applications. It was developed according to the wishes of the most demanding manufacturers, that were looking for a quantum leap in true ribbon design.
