1. Introduction
Thank you very uch for purchasing the Ca per Plus kit !
With this kit you will be able to build your own high quality full-range flat
response and guitar range flat response speaker cabinet.
The Ca per Plus cabinet is designed for the use with guitar profiling or odelling
gear, where the speaker profile / odel will re ain part of the overall sound
experience.
The frequency range of the Ca per Plus cabinet is quite large.
We do not reco ended to use it as a guitar speaker cabinet behind a traditional
valve a plifier.
The Ca per Plus is designed to leave the s allest possible footprint on the
overall sound as possible.
A traditional guitar speaker is leaves a very large footprint on the overall sound.
Such speakers act like a low pass filter and will filter any of the higher
frequencies out of the sound.
In the traditional tube world, this is a good thing, because higher frequencies
generated by distorted guitar sound will sound harsh, if the are s oothed and
even taken out of the sound.
www.kpa-solutions.com
The Ca per Plus cabinet will leave those higher frequencies intact, so that
different traditional guitar speaker odels / profiles can be heard.
The finished cabinet will give you the choice to run it in either ode FRFR or
GRFR.
If the cabinet is run in FRFR ode, it can be used the sa e way a good full range
stage onitor or even studio onitor would be used.
The use of the cabinet is not li ited to electric guitar sounds but can be used for
vocals, keyboards, acoustic guitar and even string instru ents.
In GRFR ode the cabinet is especially useful for classic electric guitar sounds.
Since the Ca per Plus cabinet is designed to leave a very s all footprint on the
overall sound, you will be able to listen to different speaker profiles or odels as
they were profiled or odelled by the gear you use to shape your guitars sound.

2. Preparation
To install the kit into the Pal er 112 unloaded cabinet you will need so e
echanical skills, several tools and so e work space.
Unless you have tools which have a suction device attached to it, there will be
dust and splinters polluting your work space and surrounding areas.
If you feel you do not have the tools, the skills or the work space, please do not
atte pt to install this kit yourself.
You can order the Ca per Plus cabinet co pletely build and finished for a
reasonable surcharge fro us.
OK, lets do it !
•Make sure you have so e flat work space available on which you can put
the cabinet onto to do the drilling and the other woodwork. A 1 x 0,6
workbench would be perfect.
•Unpack the Pal er 1x12” unloaded cabinet and take the cabinet out of the
plastic bag.
•Unpack our Ca per Plus kit and check all of its co ponents.

4. Routing the hole for the tweeter
Firstly, unscrew the 6 screws that hold the ter inal plate and re ove the
ter inal plate fro the Pal er cabinet.
If you own a 60 hole saw, put the Pal er cabinet on its back side on your
workbench and ark the centre of the tweeter hole 9,5c fro the upper inner
side and fro the right inner side of the cabinet.
www.kpa-solutions.com
Drill the hole with the hole saw into the speaker baffle.
Do not use to uch pressure on the saw and lift the saw every so often to
re ove dust and splinters fro the cutting area.
After the hole has been drilled, re ove dust fro the cabinets inside and baffle
with a vacuu cleaner.
www.kpa-solutions.com
If you do not own a 60 hole saw, the hole can be done too, but it will take a
little ore ti e and effort :
–Mark the 9,5c / 9,5c position on the baffle as shown above.
–Use a ruler and a (white) pen to extend the lines horizontally and vertically
www.kpa-solutions.com
The tweeter co es with a round rubber foa seal ring.
Align that seal ring so, that the 4 s all ounting holes accord with the lines.
Scribe the inner circle of the seal ring to the cabinets baffle with a white pencil.
www.kpa-solutions.com
Drill the first hole with a wood drill. Align the drill so that the outer dia eter of
the drill tangents the circle fro the inside. I used a 10 wood drill here to
de onstrate the process.
Drill one hole after another.
The holes should be as close to each other as possible, but stay just inside the
60 circle.
www.kpa-solutions.com
Use a flat screw driver or a chisel to cut through the left over aterial between
the holes and re ove the aterial fro inside the circle.
www.kpa-solutions.com
Use the round bastard file to file to tri the holes shape to the circle.
www.kpa-solutions.com
There is a s all nib on the tweeter at the opposite side fro the wire ter inals
which does not fit into the round cut out we just ade.
Use the bastard file again to notch the hole to fit to the nib of the tweeter.
www.kpa-solutions.com
The tweeter sits inside the baffle now.
Please do not forget to put the rubber foa seal ring between the tweeter and
the baffle.
Fix the tweeter with the 4 s all chipboard screws.
Done !!

5. Installation of the back plate
If you haven’t done already, please re ove dust and splinters fro the inside of
the cabinet now.
I also reco end to take out the tweeter again because the wires connected to
the tweeter will be in the way when you asse ble the back plate and the
ounting plate.
–Put the ounting plate into the Pal er cabinet first.
–Put the back plate into the Pal er cabinet secondly.
