Motor Assembly
The Neo motor is protected by a durable aluminum motor
cover which also acts as a heat sink to withdraw heat and in-
crease power handling along with the vented pole piece. On
top of the pole piece is a solid aluminum phase plug. The
phase plug also helps to cool the motor as a heatsink and it
eliminates compression found under a traditional dustcap. But
the reason for justifying the added expense is found in the re-
sponse, especially through the crossover region of frequen-
cies. This is accomplished by reducing pathlength differences
at the highest frequencies coming off of this midbass driver
and allowing for a much smoother blend into the lower fre-
quencies of the midrange driver.
Voice Coil & Terminals
The voice coil utilizes a high-temp 2" Til former (fiberglass/
Teflon composite). The terminals use screws rather than
springs for more secure connections, less resistance and bet-
ter conductivity. From the terminals, the wires carefully wrap
around the outer edge of the spider landing until they meet
with the spider leads symmetrically on each side of the driver.
The top of the former couples to an aluminum collet. The col-
let not only helps to dissipate more heat, but it also secures
and stiffens the joint to the cone, resulting in less cone flex and
less cone radiated distortion.
Diaphragm
Certainly, one of the most important pieces of a speaker is the
actual cone. Some audiophiles prefer paper, even with all of
the other materials available. Some people prefer polypropyl-
ene, aluminum, Kevlar, fiberglass and even bamboo. Time
always brings us new technologies and new materials. This
cone is a composite material featuring Kevlar to reinforce pa-
per. One of the secrets that make these drivers sound so good
and natural is the layer of laminated foam on the back of the
cone. Modern times require modern measures...
6.5” Midbass Features
Vehicles with a higher and more linear stage height (as the lines
on the above graph demonstrate) will earn top scores…
If all staging characteristics (depth, width, height) score well, the
soundstage will be phenomenal. Positioning of each musical
instrument and the vocalist(s) will yield a realistic and enjoyable
listening experience.
The next pic not only gives you an idea of stage width and
depth, it also gives you an idea of “imaging” (where the instru-
ments and vocals are located on the sound stage). Properly po-
sitioned speakers will not only give you great sound stage
depth, width and height, but also image well, recreating the ex-
act positions of the instruments and vocals on the sound stage.
And here is the way they judge for HEIGHT…
