The Espek is an updated version of the 5140 with marginally upgraded tweeter and midrange. I updated my 5140s with Espek tweeters when the latter failed and the difference was there but marginal.
The upgrade of 5140 from passive to active is far from marginal but night and day!
Go active and don't even think about Espek. When a driver fails or when you feel the need upgrade to Espek drivers but otherwise just go active!
