1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in
accordance with all applicable manufacturer's
instructions.
8. Do not install near any heat sources such as radiators,
heat registers, stoves, or other apparatus (including
amplifiers) that produce heat.
9. Only use attachments/accessories specified by the
manufacturer.
10. 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.
11. Exposure to extremely high noise levels may cause
permanent hearing loss. Individuals vary considerably
in susceptibility to noise-induced hearing loss, but
nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a period of time. The U.S.
Governmentʼs Occupational Safety and Health
Administration (OSHA) has specified the permissible
noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these
permissible limits could result in some hearing loss. To
ensure against potentially dangerous exposure to high
sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing
high sound pressure levels use hearing protectors
while the equipment is in operation. Ear plugs or
protectors in the ear canals or over the ears must be
worn when operating this amplification system in order
to prevent permanent hearing loss if exposure is in
excess of the limits set forth above.
Since 1992 the Epifani design team has been
working very closely with many of the worldʼs
leading bassists, developing what are regarded
as some of todayʼs finest and most rewarding
bass amplification systems. We are dedicated to
research and development, constantly evolving
innovating, and hopefully, inspiring in the
process.
All Epifani products are designed to meet the
needs of the working & traveling musician.
Portability, tone, weight, and size do matter. We
focus on real-world needs, and strive to deliver
practical products that embody superior form
and peerless function. When we design we
evaluate every aspect of the project: size, wood
type, construction techniques, cabinet tuning,
speaker quality, electronic components, weight,
versatility etc., but the most important element is
the musicality of the finished product. The
defining moment for us is when our customers
experience music without thinking or worrying
about their gear - they just play.
Epifunky loudspeakers are the result of a three-
year engineering endeavor. The drivers,
crossover and cabinet have all been designed to
achieve not only a cost-effective solution, but
exceptional sound. The cabinet is constructed
with Dado Joints, Void-free Plywood, heavy
Tolex, high-impact metal corners and a rugged
18-gauge steel grill, EpiFunky loudspeakers are
visually elegant and sturdy enough for the rigors
of the most demanding road-trips.
INTRODUCTION

Tao of Impedance, Ohmmm (Ω= Ohms) –
When connecting speaker cabinets to an
amplifier, it is important not to exceed the
minimum impedance for which the amplifier is
rated. The PS400 bass head has a minimum
impedance rating of 4Ω. If the impedance of all
speaker cabinets connected to the amplifier is
less than 4Ω, it will cause the amplifier to
overheat. When combining speaker cabinets,
use the following chart to determine the
impedance of the combined cabinets.
Speaker Cables, Resistance Is Futile – For
best results use speaker cables that are 16-
gauge or lower. For cable lengths longer than
25 feet, use 14-gauge or 12-gauge cable. A
lower number means the cable is thicker and
produces less resistance which means better
low-frequency transmission to the cabinets.
Donʼt Phase Me Bro! – When using multiple
cabinets, be sure they are all in ʻphaseʼ. If you
connect two cabinets to your amplifier and notice
a lack of bass response, most likely one of the
cabinets is out of phase. This means its
speakers are moving the opposite direction of
the other speakers causing the sound waves
from each cabinet to cancel each other out. You
can readily notice this when a single cabinet has
more bass and better response than when two
are connected. Hereʼs how to verify phase. Take
a ¼” cable. Insert one side into a cabinet and
touch the other tip of the ¼” jack to the “+” of a 9-
volt battery and the shaft to the “-” of the battery.
If all speakers move forward they are in phase.
If any of the speakers move backwards, they are
out of phase, The problem can be easily
corrected by a speaker technician.
STUFF YOU SHOULD KNOW
8Ω+ 8Ω= 4Ω
8Ω+ 8Ω+ 8Ω= 2.67Ω
8Ω+ 4Ω= 2.67Ω
4Ω+ 4Ω= 2Ω
8Ω+ 8Ω+ 8Ω+ 8Ω= 2Ω
1. Tweeter Level – Three-way switch attenuates
the output level of the tweeter. Set to HI for
maximum volume, NORM for moderate
volume or OFF to disable the tweeter.
2. Speaker Input/Output – ¼” TS Phone jacks
wired in parallel. Use only unshielded 16-
gauge or lower speaker cable to connect your
amplifierʼs speaker output to either jack. Use
the other jack to daisy-chain an additional
cabinet. Take care not to exceed the minimum
impedance of the amplifier.
