We have the Electron and Electron SE models honed, refined, and sounding better than ever. The dome tweeter array (doing all of the mid-range) is identical to the Impact Monitor and Enzo 2.7. The Impact Monitor, with it's identical array was recently tested by Sterophile magazine and the speaker produced the best 'averaged horizontal polar frequency response' ever measured in the stand mount/bookshelf loudspeaker category. A second-rate speaker isn't capable of this
As the designer, I did produce a few early sets a year ago that probably had the highest frequencies a bit too hot by +1dB. This is no longer a topic or a problem - it was addressed quickly. These types of things are very easy to adjust too - the easiest in-home method is a simple toeing of the speakers outward.
