Two 8 Ohm Speaker Cabinets

Or two 8.

Two 8 ohm speaker cabinets.

Connect positive side of speaker a to positive side of speaker c. Two 4 ohm cabinets would have an impedance of 2 ohms. A parallel wiring of 4 16 ohm speakers has a system of 4 ohms total as well. Most amplifiers on the planet can run an 8 ohm load so this is desirable.

A 4x12 cab is typically 16 ohms so when you connect two of them together in parallel the total load becomes 8 ohms. It s best to match like cabinets. To give you an example of how confusing this is imagine 2 8 ohm speakers. To simplify parallel wiring pretend your speaker system has a total of 2 speakers with 16 ohms each.

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. Remember we said if your amp can t handle a 2 ohm load it could go up in flames. The cabinet impedance depends on how the speakers are wired and may differ from the impedance of the speakers. 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.

That s why this is so important. Ohms most speakers have an impedance of either 4 8 or 16 ohms ω. If your amp says it can put out a certain number of watts at 4 ohms you can only. For instance two 8 ohm cabinets wired in parallel will have a total impedance of 4 ohms.

Wiring configuration for 4 speakers in parallel. 1 x 8 ohm speaker 8 ohm load 1x16 ohm speaker 16 ohm load two speakers remember. So if you had 2 16ω boxes then you would have a total of 8ω. Two 8ω cabinets both plugged into an amp 4ω load.

Connect negative side of speaker a to positive side of speaker b. A parallel wiring turns those 2 8 ohm speakers into a system of 4 ohms total. In parallel you simply divide the total ohm rating by the number of speakers or speaker boxes. When playing through multiple speaker cabinets one must remember that this will change the impedance that your amp must compensate for.

Match impedances ohms all speakers in the same box should have the same impedance. The most basic cabinet configuration is a single speaker. To push more air several speakers always of equal impedance can be wired together in a cabinet. One 8ω cabinet plugged into another 8ω cabinet then into the amp 16ω.

Four 8 ohm speakers 2 ohm load four 16 ohm speakers 4 ohm load four 32 ohm speakers 8 ohm load.
