I haven't had the pleasure of listening to any EPI speakers but have heard good things overall about them. Not familiar with the Model 4 but I'm sure someone here will chime in soon, they look very nice.
Uses a different woofer and tweeter than the iconic earlier models.
Memory tells me that they sounded decent, but weren't up to the "standards" of the earlier models.
For $90 I'd think twice unless you really like the enclosures and/or plan to do a refitting like Huw did... http://www.humanspeakers.com/e/epicure-4.htm
