SR
Series - Details
1.
Cabinet and Appearance
-
Cabinet
construction is 13-ply birch plywood (current SR models use 7-ply
maple). The benefit is increased structural rigidity for greater
ruggedness and reduced sidewall flexing for improved low-frequency
performance.
-
Cabinet
finish is changed to Duraflex. This provides a much more contemporary
and marketable appearance. The switch from carpet covering to DuraFlex
allows for a superior joint detail that translates to greater
structural integrity and improved cabinet rigidity.
-
All metal
handles (SR used a metal hand hold and plastic cup) are stronger and
provide a better seal to the enclosure and are less resonant than the
plastic cup design. The handle cups are stamped with the JBL logo.
-
The grill has
been changed to a full-face, 52% perforation metal design. The grill
is slightly curved and provides a much more contemporary, professional
appearance.
-
The shiny,
machined speaker basket rings have been eliminated allowing the
transducers to blend into the cabinet for a subtler, less obtrusive
appearance.
-
The Valox
corners used on SR-A have been eliminated on SR-X. Instead, the
DuraFlex coating is built up to double and triple thickness in areas
subject to impact and abrasion.
-
To prevent
the enclosures from "walking" when used under high power, heavy rubber
feet have been added.
2.
Crossover and Audio Characteristics
-
Overall, the
performance will be similar to the Sound Power line. The greater
enclosure volume of SR-X results in somewhat greater bass
extension. Off-axis response is much smoother than past SR models.
SR-X is better behaved in the crossover region than SR. The sound
is still "aggressive" but with the edges rounded off. Speech and
vocals articulate very well. Compared with competing models used for
evaluation, SR-X exhibits more "depth".
-
Crossover
network topology has been changed to Sound Power type. SR-X
adds a low-pass section for the low frequency that was absent from SR.
This results in a less "mid-heavy" sound and also smooths off-axis
response greatly.
-
The same "Bi-Amped
/ Passive" mode selector arrangement used on Sound Power has been
incorporated into SR-X.
-
In "Bi-Amp"
mode, all network elements are bypassed (in the case of SR, the HF
high-pass section remained in-circuit). SR-X will be able to
take better advantage of DSC260 capabilities when used in "Bi-Amp"
mode.
3.
Flying Versions
-
All models
except subwoofers (SR4715X, SR4718X, SR4719X) and the stage monitor
(SR4702X) will be available as flying variants.
