Replaced my AZ Crescendo MKIIs and REL R-528SE subwoofer with the Tekton DI SEs (with cables to the subwoofer, this is over $30K). The need eliminating the subwoofer was immediately apparent. The DI SEs keep sounding better with play time. They are a very revealing speaker with beautiful holographic imaging, a deep and wide soundstage, and extremely tight bass. Female vocals are to die for. Music is presented with a lifelike presentation (jazz is my preference). They get the transient details right. Tekton DI SEs are going to be a hard speaker to beat for the money.
