The phase reversal cabinet design greatly reduce the
disturbance to low frequencies and thus enhance the
sound quality.
Main Features
PRODUCT INTRODUCTION
Double 12 LF Speaker"
Double 12 LF drivers inverted low frequency speaker."
Thesoundproducedby R12iscleanpowerfulandelastic.
Frequency Response 45 Hz 300 Hz (-3dB).
Sensitivity 92 dB, Max Sound Level 122 dB.
RMS Power 900W, Peak Power 3600w.
Product Description
and structure design as well as advanced paint spraying
techniques. It is combined of two 12 LF speakers. The"
100mm flat aluminum andTIL material bracket enable full
heat radiation.The RMS of the speaker can reach 900W
and short term peak power can reach 3600W.
Thedesignofparallelmagnetic circuitcan reducethe odd
harmonic in the LF speaker to the fullest extent.
The cabinet of R12 is made of 18mm thick plywood with
stretching resistance up to 4500N.The wedge structure
frees the cabinet from any nails. The paint on the surface
has high resistance to abrasion.The inverted bass design
which provides best sound quality is used in R12. Also the
phase reversal tube is improved to reduce the wind
speed. Thus sound quality is improved by reducing the
disturbance to the low frequencies.
Thanks to the Q235 material and the powder spraying
techniques, the grill of R12 has high intensity and high salt
mistresistance.Intheatmosphereof5%sodiumhydroxide,
it has salt mist resistance duration of 96 hours. In actual
application itcankeep itselfrustfreefor5 years.The inner
side of the grill is padded with cottons to protect it from
rains.
R12is mainly appliedin meetingrooms, largemultifunction
halls, auditorium, churches and mobile performance.The
sound characteristics of R12 can be defined as clear full"
and without any compromises on the massiness."

place R12 pulling plate lockpin into the slot of R6 pulling
plate with holes against each other; put the ball-catch
bolt back.
(4) Insert connecting rod into R6 rear and angle-adjustment
slot of R12 on the bottom, adjust angle according to
practical needs.
(5) Install one or multiple sets of R6 by sequence onto the

TECHNICAL SPECIFICATIONS
Specifications SpeakerTesting Method
1. Frequency Response
Use pink noise to test the speaker in the anechoic chamber, adjust the
leveltomakethespeakerworkatitsratedimpedanceandsetthe output
power at 1W, then test the frequency response 1m away from the
speaker.
2. Sensitivity
Use full range Pink noise which has been modified using an EQ
curve to test the speaker in the anechoic chamber, increasing the
signal to make the speaker work at its rated impedance and set the
power output at 1W, then test the sensitivity 1m away from the
speaker.
3. MAX.SPL
Use full range Pink noise which has been modified using an EQ
curve to test the speaker in the anechoic chamber , increase the
signal to make the speaker work at its maximum power output
level, then test the SPL1m away from the speaker.
4. Rated Power
Use pink noise to the IEC#268-5 standard to test the speaker,
increase the signal for a continuous period of 100 hours, the
rated Power is the power when the speaker will show no visible
or measurable damage.
