Technology
All Quantum™ combos and cabinets
are loaded exclusively with speakers
featuring Neodym magnets. Not only
does this technology significantly reduce
weight, it also creates a more concentrated
magnetic field that considerably enhances
response.
These speakers feature integrated HF
systems designed to render the crucial
overtone spectrum with utmost uni-
formity. While the 10" speakers use
parallel membranes (that is a dual cone
design) to this end, the 12" and 15"
woofers feature a fresh new technology.
A machined aluminum cone (Dura
Dome™) renders the voice coil’s high
frequency output. Both of these techno-
logies deliver true response, a wide
pattern of throw, and a rich overtone
spectrum that blends perfectly with the
low and mid-frequencies produced by
the main membrane. Many years experience designing, tuning
and manufacturing speaker enclosures
enabled the Quantum™ development
team to build cabinets that – like fine
acoustic instruments - make the most of
resonances. Ingeniously engineered
panels and bracings, as well as the robust,
six-ply Okumé wood (with about half the
weight of standard cabinet woods),
deliver powerful, punchy low-end
projection and finely balanced, crisp
midrange. Because the resonant enclosure
is tuned to radiate uniformly across its
entire surface area, the bass signal can be
localized precisely from any position on
the stage.
