Series enclosures have been designed to provide excellent tone with a fast
attack, deep low-end and punchy output. The 4.5XL features four 10”, propri-
etary low frequency drivers with specially designed aluminum cones, large voice
coils on Kapton formers, impregnated fabric surrounds, and matched convex
dust covers all mounted in a heavy-duty steel frames. Rounding out the tone is
a proprietary 5” aluminum mid-range driver. Using heavy-duty plywood con-
struction, covered in rugged carpet with recessed jack plate and ergonomic
metal handles, the 4.5XL will provide reliable performance from gig to gig and
venue to venue.

About Impedance
Before you hook up your speaker cabinet, be sure that you understand a little about
impedance. Impedance is the electronic load that the speaker puts on the power amplifier
and is measured in Ohms.
Here is the tricky, yet simple rule of impedance: When two speakers, of equal impedance
are wired in "Parallel", the total imped-
ance is cut in half and when two speak-
ers are wired in “Series”, the total
impedance is the sum of the speakers
individual impedance.
The 4.5XL impedance is 8 Ohms. So,
when two 4.5XL’s are connected
together in parallel, the total impedance
is 4 Ohms. The impedance of your
speaker also has an effect on your
amplifier. In general, the lower the
impedance, the more power your ampli-
fier will put out.
IMPORTANT: There is a minimum safe
impedance so be sure to check the
manufacturer’s recommended imped-
ance for your amplifier to avoid any
damage to your amplifier or voiding
your warranty.
Connecting the 4.5XL to Your Amplifier
The 4.5XL connections are made via
1/4” phone jacks located on the rear
panel jack-plate. Be sure to make your
connection with un-shielded speaker
cable. Connect the Amplifier Output to
the speaker Input on the 4.5XL’s rear
jackplate.
Using the EXTENSION Output
The 4.5XL provides a convenient
Extension Output for connecting addi-
tional speaker cabinets in parallel. Be
sure to read the section above on
impedance to insure a proper hook up
with your amplifier. Follow the steps
below to connect two 4.5XL’s using the
Extension Output. Connect the
Amplifier Output to the Input of the first
4.5XL. Now, connect the Extension
Output to the Input of the second
4.5XL.
