Speaker Switch F&Q's

What are the differences between the speaker switches in terms of impedance

All the speaker switches are configured so that if you use 8 Ω speakers the minimum impedance seen by the amplifier will be 4 Ω

What are the benefits of series vs parallel switching?

Switches which have more than two sets of speakers use a combination of either series or parallel switching to achieve the impedance of 4 Ω no matter what the combination of speakers are switched on. For two way switches, there is a choice between series or parallel versions. If you have 8 Ω speakers (and a 4 Ω min amp) you should always use the parallel switch. If you have 4 Ω speakers and a 4 Ω min amp you should always use the series switch.

All QED switches load on 4 Ω using 8 Ω speakers. What happens if my speakers are 6 Ω?

Firstly check if your amp can cope with a 3 Ω load or less (some can) then you are fine. The rule is you must always use speakers with double the impedance of the amp minimum. If you only have two pairs of speakers then use the two-way SERIES switch.

How do the switches deal with power, e.g. if I have an amplifier with more than 150 watts?

QED switches are rated at 6A which means the max power they can handle is 288W given an 8 Ω load

If my amp is rated 6-16 Ω should I really be running a 4 Ω load?

NO, NEVER - you should only use 12 Ω speakers. You can also get 16 Ω speaker. But in many cases, it may just be easier to change the amp.
