Arc Audio Speakers
For audiophiles who value precision over loudness, Audiocircle represents the modern evolution of German engineering. Born from the legacy of Rainbow Audio, founders Paul Jelko and Marc Seigerschmidt have created a brand that focuses purely on the "circle" of sound—natural reproduction, tonal balance, and mechanical integrity. Unlike mass-market brands that prioritize flash, Audiocircle speakers are understated "wolves in sheep's clothing," built with acoustically inert baskets and exotic cone materials to vanish into your door panels, leaving only the music behind.
Choosing the Right Audiocircle Collection
The Audiocircle hierarchy is designed to match different levels of amplification and installation complexity. The **Munich Series (ML)** is the "Sound Terrain" all-rounder, designed to offer a significant upgrade over factory speakers with a warm, sandy-coated paper cone that is forgiving and easy to drive. Stepping up to the **Hamburg Series (HL)** brings you into the realm of "Brain and Brawn." With a rigid black aluminum cone and an acoustically dead ABS basket, it offers faster transient response and higher power handling for spirited listening. For the uncompromising enthusiast, the **Berlin Series (BL)** is the "Performance" line. It combines the best of both worlds with a unique Aluminum-Paper composite cone and a die-cast aluminum chassis, delivering the warmth of paper with the snap of metal for a truly reference-grade experience.
Technical Features
Audiocircle differentiates its lines through material science. The Berlin Series features a **Blackened Aluminum-Paper Composite Cone**, a hybrid material that eliminates the "ringing" often found in pure metal cones while maintaining superior stiffness. The tweeters across the board utilize **Silk Domes**, but the Berlin line upgrades to a hand-coated 26mm version for extended high-frequency air. Additionally, the Hamburg and Berlin series utilize **Closed Chamber Tweeters**, which lower the resonant frequency (Fs), allowing the tweeter to play lower and blend more seamlessly with the midrange driver.
Installation Advice
While Audiocircle speakers are designed with standard DIN dimensions for easier fitment, their performance relies on solid installation. The Munich series is forgiving in standard door locations, but the Hamburg and Berlin series, with their stiffer suspensions and higher power handling, benefit significantly from sound deadening in the doors to prevent panel resonance. The Berlin series tweeters are slightly larger (26mm), so ensure you have adequate depth in your A-pillars or sail panels for a flush mount.
