* Banana pulp blended light-weight cone paper / High-loss
foamed rubber surrounding
Blending a banana pulp with two wooden pulps holding different physicality realizes a sufficient stiffness and high-loss. A
high-loss foamed surrounding with an up-roll shape is
employed.

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all Instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or
other apparatus (including amplifiers) that produce heat.
Do not defeat the safety purpose of the polarized or grounding type plug. A
polarized plug has two blades with one wider than the other. A grounding type
plug has two blades and a third grounding prong. The wide blade or the third
prong are provided for your safety. If the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.
Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
Only use attachments/accessories specified by the
manufacturer.
Use only with the cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the apparatus.
When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods
of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or
has been dropped.
The apparatus shall be used in an open area.
15.
Apparatus shall not be exposed to dripping or splashing and that no objects filled
16. with liquids, such as vases, shall be placed on apparatus.
Mains plug is used as disconnect device. It shall remain readily operable and
17. should not be obstructed during intended use. To completely disconnect the
apparatus from supply mains, the mains plug of the apparatus shall be
disconnected from the mains socket outlet completely.

* Mechanical 2-way center cap
The same material as the cone paper is employed on the center
cap for improving the sound unification. A mechanical 2-way
structure which directly connects the center cap with the voice
coil bobbin extends a high range sound reproduction further.
Thank you for purchasing P650K.
Read through this manual so that you can correctly use it.
The lightning flash with arrowhead symbol, within an equilat-eral
triangle, is intended to alert the user to the presence of uninsulated
"dangerous voltage" within the product's enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to persons.
CAUTION
The P650K is a suitable full range speaker driver especially for
first time craft users. A light-weight cone paper and a high-loss
rubber surrounding realize a bright and clear mid-to-high range
and reasonably damped low range reproduction. You can enjoy an
excellent stereo image and sound field achieved by the small-diameter speaker unit.

Recommended enclosure
For the easy start, we recommend a combination with a P650-E
enclosure kit. The P650-E is designed for the P650K that can
easily achieve the enticing full range speaker system. The
P650-E comes with the speaker terminals, internal wirings and
sound absorbent pre-fitted and acoustically tuned. Please use the
P650-E taking advantage of easy mount.
To enhance the low frequency more than P650-E, we recommend
the use of P1000-E. As the internal volume is larger, you can feel
low frequency more. In this case, since P650K cannot be mounted
directly, prepare the baffle board as shown in the drawing on the
right. The board material is MDF with t9 thickness, the baffle hole
is 60mm diameter. As the screw position is made as φ116, you
can easily replace the speaker driver with P1000K.
