Solid-state Amps: Most solid-state amplifiers would rather look at an open circuit no speaker at all than a load. Therefore, you can usually use a load that is higher than the recommended load. Do not use a lower impedance load, as this could cause serious damage to your SS amp. Tube Amps: On the other hand, most tube amplifiers need a load to avoid transformer or tube socket damage. If a mismatch can not be avoided on a tube amp, it is better to go towards a lower impedance rather than too high of a speaker impedance. This may stress the tubes some, but, tubes are cheaper than transformers.

One-Wire Alternators: Are They Better Or Just Easier To Hook up?
A: There are many variables to consider when connecting 4 ohm speakers to your system. Please consider the following:. Receivers: Most midfi Receivers may have problems adequately driving a 4 ohm load. However, many of the better Receivers today have a large enough power supply, heat sink area, and current capability in the amp sections to handle 4 ohm loads.



Amplification can be confusing to a newbie coming from a combo amp. If you are new to amps and cabs, this article should be helpful in explaining what speaker impedance is, and how it works with your amp head. When we first make this big step to a new rig, there are many questions floating through our mind, because we are presented with countless options.
