Kef R300 Speaker Drive Unit Testing

By now you’ve probably seen my testing of the Kef Q100 drive unit. I had read the next step in the Kef Uni-Q line are the drivers in the “R” series. So, a fella let me borrow the 5 inch midrange drive unit from the R300 speaker to test. The R300 comes with a separate woofer but I was not sent this. The only way to obtain these drivers individually is to purchase the speakers they come with (such as the R300 or R500 speaker) and remove them. Which brings up something worth noting: I am testing these raw drivers as more or less for knowledge purposes. These kind of tests tell us exactly what the basis for a speaker is (drive units + enclosure + circuit design). If Kef is starting with a great drive unit then one can logically assume they have likewise extended efforts to use them as a speaker component in a manner which reflects their ‘raw’ performance. In other words, if the drive unit design is great, odds are so is the complete speaker it’s used in. Now, let’s get on with it!
