Speaker Guidelines
• DO NOT connect a speaker load with a total impedance below the minimum rating of your amplifier to prevent damage to your equipment.
• DO NOT connect speaker(s) with a total power handling capacity that is less than the power output rating of your amplifier to prevent damage to your equipment.
• ALWAYS switch your system power OFF before connecting or disconnecting speakers.
• ONLY use unshielded speaker cable of 18 gauge or heavier (16 or 14 gauge) for speaker connections. Shielded instrument cable WILL NOT work and may damage your equipment.
• ONLY connect one amplifier to each speaker load. Two amplifiers connected to a single load WILL NOT
work and may damage your equipment.
Use the impedance and power ratings on your amplifier and speakers to determine if a particular combination
of speakers is appropriate for your amplifier. NOTE: All SWR® speaker enclosures, as well as most others, will be connected in parallel (NOT series) when linked
The speaker illustration gives you the total impedance load calculations for various speaker impedance combinations (Ω=ohms). The ideal speaker load (total impedance) is equal to the minimum impedance
rating of your amplifier. 
Operating below the amp's minimum impedance rating can overheat your amplifier and cause damage. Operating above the amp's minimum impedance rating, while safe,
reduces the amplifier’s maximum power output.
Something else to consider: You can obtain the 
same group total impedance load from different combinations of speaker impedances (see illustration). If each speaker in a group has the same impedance, each speaker will receive the same amount of power from your amplifier. However, if
impedances are not all equal, the lowest impedance speakers will get the most power. For example, if you connect an 8Ω and a 16Ω speaker to an amp output
of 30 watts, the
Take this into consideration when calculating power handling capacities and when positioning your speaker enclosures.
