Two 8 Ohm Speaker Cabinets

So if you had 2 16ω boxes then you would have a total of 8ω.

Two 8 ohm speaker cabinets.

To give you an example of how confusing this is imagine 2 8 ohm speakers. That s why this is so important. A 4x12 cab is typically 16 ohms so when you connect two of them together in parallel the total load becomes 8 ohms. To wire a 4x12 cabinet in series parallel where four 8 ohm speakers are wired in series parallel equaling a total load of 8 ohms as in the illustration below.

The 4x12 cabinet is sometimes referred to as a half stack and players routinely connect two of them to a single amp to create a full stack. Two 4 ohm speakers 8 ohm load two 8 ohm speakers 16 ohm load. To simplify parallel wiring pretend your speaker system has a total of 2 speakers with 16 ohms each. Wiring configuration for 4 speakers in parallel.

For instance two 8 ohm cabinets wired in parallel will have a total impedance of 4 ohms. It s best to match like cabinets. Running cabinets in this fashion from one power amp will give you a 2. To push more air several speakers always of equal impedance can be wired together in a cabinet.

Match impedances ohms all speakers in the same box should have the same impedance. In parallel you simply divide the total ohm rating by the number of speakers or speaker boxes. One 8ω cabinet plugged into another 8ω cabinet then into the amp 16ω. The most basic cabinet configuration is a single speaker.

Remember we said if your amp can t handle a 2 ohm load it could go up in flames. Connect negative side of speaker a to positive side of speaker b. Two 8ω cabinets both plugged into an amp 4ω load. Ohms most speakers have an impedance of either 4 8 or 16 ohms ω.

When playing through multiple speaker cabinets one must remember that this will change the impedance that your amp must compensate for. If your amp says it can put out a certain number of watts at 4 ohms you can only. A parallel wiring turns those 2 8 ohm speakers into a system of 4 ohms total. Or two 8.

The cabinet impedance depends on how the speakers are wired and may differ from the impedance of the speakers. 1 x 8 ohm speaker 8 ohm load 1x16 ohm speaker 16 ohm load two speakers remember. Two 4 ohm cabinets would have an impedance of 2 ohms. Most amplifiers on the planet can run an 8 ohm load so this is desirable.
