Description
The latest version of the SP™ 7 has
the new BWX high power Black Widow
woofers incorporated, as well as a very
nice looking cabinet design. The SP 7X is
a quasi three-way speaker system
comprised of a pair of 15" Black Widow
BWX woofers with Kevlar
®
impregnated
cones, and a 44XT compression driver
loaded onto a CH 7 constant directivity
horn.
The SP 7X has a trapezoidal shaped
enclosure, which reduces the build-up of
standing waves inside the enclosure,
which minimizes mid-bass and mid-range
colorations due to the cabinet. It is
constructed of 3/4" OSB and is covered
with a durable black carpet. The enclosure
corners are reinforced with polymer caps,
and a black powder-coated expanded
metal grille covers the lower portion of the
system to protect the woofers from
external damage. Built-in pocket casters
on the rear bottom edge ease transport
when smooth flooring or paved areas are
present.
The quasi three-way system consists
of a pair of 15" Black Widow BWX woofers
with Kevlar impregnated cones, and a
water-resistant treated cone and dust cap
for superior environmental stability.
Capable of over 500 W of continuous
power handling each (AES Std 2-1984),
the woofers can handle a lot of sheer
power. The high frequencies are handled
by a 44XT
™
4" titanium diaphragm
compression driver, utilizing ferrofluid
cooling, coupled to a CH 7 constant
directivity horn. This horn has a smooth,
even response with good pattern control.
The 44XT driver features the Radialinear
Planar Phase Correction System, under
US Patent 6,064,745, which provides
smoother and extended high frequency
response.
Input connection to the system is
made via two 1/4" phone jacks in parallel,
and a 4-pin Neutrik switching jack is
provided for bi-amping flexibility, while
maintaining superior signal integrity. The
internal passive crossover features Sound
Guard 44 tweeter protection circuit, an
advanced topology crossover with high
performance components, to provide high
power handling and reliability. Peavey’s
proprietary high-frequency driver
protection circuitry, Sound Guard, provides
long and medium-term driver overload
protection when the system is used fullrange, or when it is bi-amped, without
impairing musical transients or dynamics.
The crossover provides driver roll-off and
protection, as well as driver EQ for the
woofers and horn; the sum total is a clean,
clear and smooth response. The lower
woofer is rolled off before the mid-range
crossover point, so it does not interact
adversely with the upper woofer, which
operates into the mid-range. High-quality,
reliable crossover components include
polypropylene capacitors, and linear high
current inductors. The optimal integration
of the crossover with the selected drivers
results in a smooth frequency response
from 50 Hz to 19 kHz. A crossover EQ
switch is provided to tailor the response in
the mid-range, providing a nominally flat
frequency response position, and an EQ’d
position that pulls the mids back to help
keep bright rooms from overloading, or to
help achieve a mellower voicing for those
applications that prefer it, such as DJ use.
With a double 15" woofer based
enclosure and a horn-loaded 2" throat
compression driver, this system can put
out some very serious sound levels, and
take 2,000 Watts program of clean
amplifier power, resulting in precise
coverage with awesome clarity and high
reliability.
Frequency response
This measurement is useful in
determining how accurately a given unit
reproduces an input signal. The frequency
response of the SP 7X is measured at a
distance of 1-meter using a 1 Watt (into
the nominal impedance) swept-sine input
signal. As shown in figure 1, the selected
drivers in the SP 7X combine to give a
smooth frequency response from 50 Hz to
19 kHz.
Power handling
There are many different approaches
to power handling ratings. Peavey rates
this loudspeaker system’s power handling
using a full-range form of the AES
Standard 2-1984. Using audio band 20 Hz
to 20 kHz pink noise with peaks of four
times the RMS level, this strenuous test
signal assures the user that every portion
of this system can withstand today’s high
technology music. This rating is contingent
upon having a minimum of 3 dB of
amplifier headroom available.
