Further down this page you will see some pictures of a pair of later 3×10 cabs that I used to have in my collection and which have different drivers.
I acquired this set of four 3 x 10 PA cabs in October 2019. These cabs are sometimes found in pairs of 3×10 cabs but were normally sold as 2 pairs of 2 cabs, so 4 cabs in total and they were advertised as 6×10 cabs. Each pair had a top and a bottom cab with 3 x 10″ drivers in each, thus making a total of 12 x 10″ drivers. The 3 drivers in each cab are 8 ohms linked in series giving the cab a total of 24 ohms. The 4 cabs should all be linked in parallel thus giving a total of 6 ohms which was the standard output on WEM 100 watt power amps such as the PA100 etc.. The drivers have no power handling label on them but I would estimate they are around 10 watts per driver, thus making each cab capable of handling around 30 watts and a total of around 120 watts for a set of 4 cabs. Two of these cabs currently in my collection have their original 10″ Elac drivers but the other two have been modified to take more recent 8″ drivers. The cabs link together using the catches shown in one of the pics. It’s quite rare to find these catches still in place.
The following cabs are no longer in my collection. They have sequential serial numbers and look absolutely identical from the outside but, very strangely, they have different drivers fitted. One of them has Elac drivers and the other has Peerless drivers. There is no indication that any of the drivers have been replaced or re-fitted so I believe they are original and I can only assume that WEM had a stock Elac 10″ drivers and a stock of Peerless 10″ drivers and it was just pot luck which drivers were used. I’ve attached pics of both sets so that you can see the difference.
