Description:
The latest version of the SP 6X has the
new RX 22 high frequency compression
driver incorporated, as well as a very nice
looking cabinet design. The SP 6X is a
two-way speaker system comprised of a
12" Sheffield®woofer and an RX 22
compression driver loaded onto a CH
®
3
constant directivity horn.
The SP
™
6X 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 1/4" high density particle
board 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 half of the system to
protect the woofer from external damage.
An SA-1 stand mount adaptor is built-in
for ease of speaker stand use.
SPECS
PEAVEY ELECTRONICS
The two-way system is comprised of a
12" Sheffield
®
woofer with a highly linear
suspension. The high frequencies are
handled by an RX™22 two-inch titanium
diaphragm compression driver utilizing
ferrofluid cooling, coupled to a CH
®
3
constant directivity horn. This horn has a
smooth, even response with good high
frequency dispersion. The RX 22 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.
The internal passive crossover features
Sound Guard
™
III 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, without impairing musical transients
or dynamics. The crossover provides
driver roll-off and protection, as well as
driver EQ for the woofer and horn, the
sum total is a clean, clear and smooth
response. High-quality, reliable crossover
components include polypropylene
capacitors, and high current inductors.
The optimal integration of the crossover
with the selected drivers results in a
smooth frequency response from 70 Hz
to 17 kHz.
Despite its compact dimensions for a
12" based enclosure, this system can put
out some very serious sound levels, and
take 500 Watts program of clean amplifier
power, resulting in clean coverage with
excellent clarity.
If the bulb in your Sound Guard should
ever burn out, a replacement may be
obtained from an Authorized Peavey
Service Center. However, if a Peavey
replacement bulb is not readily available,
an automotive type SK 3 clip in bulb may
be substituted for temporary use until a
Peavey bulb can be obtained.
Frequency Response:
This measurement is useful in
determining how accurately a given
unit reproduces an input signal. The
frequency response of the SP
™
6X 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 6X combine to give a smooth
frequency response from 70 Hz - 17 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.
Mounting
Caution: This unit is not designed for
overhead supesion.
