If they were built by the original a/d/s company they should be awesome, however if they were built under the new DEI ownership I would have to question their quality. a/d/s has always made quality components on par with Focal, Morel, Vifa, and Dynaudio. Their tweeters are some of the most detailed and clean sounding ones that I have heard and the crossover networks that come with the 345is's are superb. The only way to make them even better is to replace the caps in the networks with Hovland's or AudioCap Theta's to take them to another level.
