Europa Max
The legend of Europa. Even better.
Europa Max offers a clearer and more
dynamic presentation than Europa, and
an even harder-hitting, well-defined bass.
One cast marble body. Two legendary performers.
Summary: Designer’s concept
Within two months of the Callisto’s debut, the Europa Max was born. It’s a marriage
between the Callisto’s woofer, tweeter, and crossover circuit and a Europa cabinet.
That new crossover circuit could have only been developed using the Callisto’s cabinet,
so I could hear exactly how to fine-tune it. Only then could those parts be moved into
a Europa cabinet and the differences assessed to see if this was a worthwhile venture.
The first thing I heard was that the bass had more impact. Textures of voices and
instruments were more clear and the treble positively sparkled. Dynamics were more
effortlessly alive, even when heard from another room. The Max is louder at the
same volume setting and also handles more power than the Europa. It plays far
louder than Europas—enough to fill a large room. For all these differences to be
heard, the basic design of the Europa’s Q-Stone™ cast marble cabinet proved itself.
The drivers are very special, with a woofer that maintains very low distortion—no
matter how hard it’s driven or what note is played—from the lowest bass to the highvoice range. No other woofer comes close to this level of performance. The tweeter
itself is unique in its ability to go very high—beyond audibility without ringing—thanks
to its very light, treated linen dome. It goes very low with ease, because of its special
suspension—it’s extremely flexible and responds, microscopically, to the most delicate
of signals. As with the Europa, a soft, absorbent wool felt surrounds the tweeter to
prevent reflections and more is used to limit the dispersion of the high-voice and
treble directly to the sides, and up and down the face of the speaker—a feature
especially necessary for small rooms. The crossover circuit feeding both drivers passes
the high and low signals through at the same instant, so both drivers can move as if
they were one unit. Only our Balanced-Phase™ ‘first-order’ crossover circuit provides
the precise timing that lets us hear the music, not a separate woofer and tweeter.
Hear it all.
Every sound is more easily heard, more deeply felt. I believe the Max is aptly named,
for it achieves all of the goals needed in a speaker that can be kept for life.
It’s about...time.

Comments: MountainEars
“The imaging, detail, and transparency are extraordinary...”
“Based on my ears alone, I’d think these were very large, and much more expensive, speakers. They effortlessly
fill my 13x22x8 space, and I suspect would do as well in a space two or more times that size. The imaging,
detail, and transparency are extraordinary. I’m an accomplished (amateur) cellist, and I’ve never heard the
sound of cellos reproduced this accurately before. They’re truly ‘right there.’ I loved my classic Spica TC-50’s—
known for their precise imaging and musicality—and my new MAX’s are all they were and a lot more—extended
top and bottom-end response, greatly enhanced detail. Roy provided advice every step of the way to optimize
the MAX’s performance in my system.”
“I can’t believe the quality of music I’m hearing...”
”Just a quick note to let you know my Europa Maxs arrived just fine. Even though they’re right out of the box, I
can’t believe the quality of music I’m hearing. Thank you so much for such a fine product at such an ordinary
price. If I upgrade, I’ll sell these to my son.”
