The LS3/5A speakers were designed by BBC engineers for mobile monitoring use. They needed to be compact, so they could be fitted into BBC vans. BBC did not produce the speakers themselves, instead, they outsourced production to number of British companies (e.g. Rogers, Kef, Spendor, Goodmans, Chartwell, etc.). From what I gathered, Rogers LS3/5A are most popular, and therefore, cheapest to buy. The other brands are more sought after, and consequently, more expensive. All of these manufacturers used Kef drivers (T27 SP1032 for tweeter and B110 SP1003 for bass). It is important to mention that not all of the B110 drivers produced by Kef were the same. The variations on the production line where quite high, which meant that only small percentage of these drivers were approved by BBC and used for LS3/5A production.
