Europa
“...giant killers...”
“...unsurpassed...”
“...changed my life...”
“...amazingly coherent...”
“I’ve found sonic nirvana...”
Summary: Designer’s concept
Europa was introduced in the fall of 2001 and, along with other breakthrough advancements, was the first speaker to have
an all-cast marble cabinet. Breakthroughs in its circuit design led to the most perfectly-synchronized motion between the
woofer and tweeter that had ever been achieved. This method of engineering circuits is still used for every model we
manufacture. It’s the only circuit which allows the signals to pass through with no unnecessary time delays and feeds both
drivers (woofer and tweeter) at the same instant. After installing the drivers and new crossover circuit into the cabinet, I sat
down for a good listen. The increase in bass was shocking. The marble’s rigidity and its airtight nature proved their worth.
The Europa’s unique woofer was first installed in 1998 in its forerunner, the Continuum 0.5 bookshelf speaker, and has
been included in several other models since then. It remains unsurpassed in its ability to play both very softly and very
loud—with very-low distortion—because of its patented neodymium magnet structure, supple suspension, and light, rigid
cone. The Europa’s tweeter is one of the few that don’t depend on reflections from cabinet surfaces around it to produce a
proper tone balance. Thus, it’s surrounded with a very absorbent pure wool felt. Sounds from the tweeter leave very
quickly, cleanly, and delicately. The tweeter’s treated dome is light, rigid, and doesn’t ring. Its unusual suspension is very
soft and flexible and reproduces the smallest of sounds.
Once the sound finally leaves a cabinet, it travels towards the listener and changes little along the journey. We take
advantage of the final opportunity to further control the sound waves by placing an arrangement of wool felt near the
woofer and tweeter. This keeps the Europa from talking directly to the walls next to it and allows more freedom in speaker
placement. The most important aspect is that the listener should never hear the woofer’s and tweeter’s sounds separately
in time. One should hear only one ‘driver’ moving back and forth—or one ‘source,’ for the most clarity. Ears are very
sensitive to time delays, and even small deviations from ‘time-coherent,’ or synchronous, motion of the woofer and tweeter
tell our ears that the speakers are ‘speakers’ and not the real thing.
The woofer and tweeter move as one unit because our revolutionary, Balanced-Phase™ ‘first-order’ crossover circuit delivers
their signals with no delays. The drivers truly mimic each other in their entire transition zone. A speaker is a simple system and
when all of its parts move together as well as they do in the Europa, one hears everything recorded in the original source
material—in the way it was intended to be heard. I’m honored to offer to you such stellar, time-coherent clarity.
Hear it all.
It’s about...time.
