Asked Questions about the SR-X Series
has the cabinet and appearance changed from the SR Series and SR Series
about the crossover and audio characteristics?
all SR-X models available in flyable versions?
DSC260 and DSC280 programs be available?
Cabinet and Appearance
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.
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.
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.
grill has been changed to a full-face, 52% perforation metal design.
The grill is slightly curved and provides a much more contemporary,
shiny, machined speaker basket rings have been eliminated allowing the
transducers to blend into the cabinet for a subtler, less obtrusive
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.
prevent the enclosures from "walking" when used under high
power, heavy rubber feet have been added.
Crossover and Audio Characteristics
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".
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.
same "Bi-Amped / Passive" mode selector arrangement used on
Sound Power has been incorporated into SR-X.
"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.
models except subwoofers (SR4715X, SR4718X, SR4719X) and the stage monitor
(SR4702X) will be available as flying variants.
DSC260 and DSC280 Programs
DSC280 settings will be available. DSC260 tunings can be found here.
