About your new loudspeakers
Thank you for purchasing the a/d/s/ 336PX loudspeaker system. The 336PX is without
question the finest automotive loudspeaker a/d/s/ has ever produced. It reflects most refined
technology combined with obsessive construction techniques to deliver unequalled
performance. The 336PX is assembled by specially trained craftspeople with years of
experience building a/d/s/ products. This elite group maintains extremely tight tolerance
control at each step, which assures that each 336PX precisely matches the performance curves
of the original reference.
The most obvious feature of the 336PX is the rugged and non resonant machined metal
woofer frame. This precision chassis is hand assembled from specially selected components to
assure that each frame has the precise geometric proportions for optimum performance. The
large open area and round support rods eliminate the reflections from the frame ribs which
can cause midrange coloration in ordinary loudspeakers. The frame’s bi-metallic construction
forms a resonance-canceling structure which guarantees the utmost sonic purity.
The woofer cone is a newly designed composite of a proprietary copolymer modified with a
filling made of an acid metasilicate of magnesium. This filling forms microscopic platelets
which help stiffen the cone while simultaneously providing a lossy mechanism to damp
undesired resonances.
The motor structure of the 336PX utilizes new geometry to create a symmetrical magnetic
field for low distortion. Also, to ensure high power handling, the center pole is vented along
with a series of perimeter vents to cool the voice coil.
The 336PX tweeter is based on a long line of a/d/s/ designs revered for their clarity and smooth
response. In the 336PX, the new conformal grille and solid aluminum mounting system help
to improve power response and dispersion.
And finally, the crossover used in the 336PX contains components which were each selected
for their own unique sonic signature. The capacitors are all high-quality polypropylene-film
types which have extremely low loss, and do not exhibit the harsh edgy sound of electrolytics
or the clarity-robbing softness of polyester types. For optimum ultra high frequency
performance, the series capacitors in the tweeter circuit are further bypassed with unique
thick-film Polypropylene capacitors specially made with stranded lead wires. This reduces the
loss caused by the main capacitors’ parasitic inductance, increasing clarity and improving
transient response. The crossover is mounted on an aluminum baseplate with a polished
acrylic cover, thereby keeping ferrous materials away from the circuitry as much as possible.
