RBX Series Bass Enclosures
Setup & Maintenance
Packaging:
The carton and packing materials used in
shipping your new product were specifically designed
to cushion it from the shocks and vibration that occur
during transport. We suggest that you save the carton
and packing materials for use in shipping.
Transporting:
During transport, do not stack more
than one cabinet or any additional equipment on top of
the cabinet. The castors are not designed to handle the
weight of more than one cabinet. In situations where
the castors do not roll easily, remove castors and use a
handtruck instead. If traveling with the unit frequently,
we recommend a road case or cover to protect it from
scratches and road wear.
Stacking:
To insure the safe setup of the RBX series
cabinets please follow these basic procedures. Remove
castors from both cabinets before stacking. Never stack
more than two cabinets when in use. Make sure that
interlocking corners are securely seated. No additional
cabinets should be stacked on top of the RBX.
Caution
DO NOT
connect more than one amplifier to your
speaker enclosure. This will cause damage to your
equipment.
DO NOT
use shielded instrument cables to con-
nect to your speaker enclosure. Use only unshielded
speaker cables of 18 gauge or heavier for speaker
connections.
DO NOT
connect speakers with a total power
handling capacity below the power output rating of
your amplifier. If your amplifier is rated at 400 watts
at 4 ohms, then the combined power handling of your
speaker enclosures should be 400 watts RMS or high-
er at 4 ohms. See IMPEDANCE GUIDELINES for
additional info.
DO NOT
connect speakers with a combined total
impedance that is below the minimum rating of
your amplifier. Doing so may cause damage to
your gear. Using speakers with a total impedance
above the minimum power rating of your amplifier
is safe.

1) Speakon® Connector:
A high current speaker
connector. Use the provided 4-conductor Speakon®
cable for Horn Bi-Amp operation. Pins 1+ and 1- con-
nect the main amplifier to the woofers. Pins 2+ and 2-,
connect the horn amplifier to the tweeter. You may
use a standard 2-conductor Speakon® cable for full
range operation .
2) Mode Switch:
Switches between Horn Bi-Amp
mode and Full Range operation. When using this
cabinet with a Horn Bi-Amp compatible head such as
the 1001RB-II, this switch should be set to BI-AMP.
For operation with all other amplifiers this switch
should be set to FULLRANGE.
3) Full Range ¼’’ Input Jack:
Using a standard ¼’’
unshielded speaker cable, this input jack provides full
range operation with any bass amplifier head. Horn
Bi-Amp mode will not work with this jack. RBX
cabinets ship with a removable plug in the 1/4” jack.
DO NOT use tools to remove this plug. It can easily
be removed with your fingers.
4) High Range Attenuator:
Adjusts the volume level
of the horn when the cabinet is in Full Range mode.
When in Horn Bi-Amp mode, this control is bypassed
and the horn level is adjusted by using the Tweeter
control on the front panel of the amplifier.
