HyDrive 112b Bass Cabinet
When connecting the HyDrive 112b to an
amplifier, only use unshielded speaker cables.
Connect your amplifier output to the speaker
input on the HyDrive 112b jack plate.
IMPORTANT: Every amplifier has a minimum
safe operating impedance, so be sure to check
the manufacturer’s recommended impedance
for your amplifier to avoid any damage to your
amplifier or voiding your warranty.
The HyDrive 112b impedance is 4 Ohms. When
two cabinets are connected together in parallel,
the total impedance is 2 Ohms. The impedance
of your speaker has an effect on your amplifier.
In general, the lower the impedance, the more
power your amplifier will output.
Basically, impedance is the amount of current that will flow through a speaker at
a certain voltage. It is measured in Ohms (Ω). The actual impedance of a speaker is
not constant across all frequencies. So, for convenience we use the term “nominal
impedance”, which refers to the impedance that a speaker presents to an amplifier at
a reference frequency.
A speaker typically has an impedance rating of 4Ω, 8Ω, or 16Ω. Generally, the lower
the impedance of a speaker, the more power will be developed by the connected
amplifier. For example, a 4Ω speaker will extract more power from your amplifier
than an 8Ω speaker. If you connect a speaker with an impedance lower than the
amplifier’s output rating, the amplifier can overheat and damage the power output
section. It is important to learn how to connect multiple speaker cabinets safely
without damaging the speakers or the amplifier in this way.
Here is a simple rule of impedance: When two speakers with the same impedance are
wired in
parallel, the total system impedance is cut in half, and when two speakers
with the same impedance are wired in series, the total impedance is the sum of the
speakers individual impedance.
