We always encourage customers to use passive room treatment whenever possible. That said, using room correction can have great benefits. Not all room correction systems are equal. Some of the software add-on systems are OK but not state-of-the-art. We use the Trinnov ST2 with our system. One of the best systems available. Truly SOTA.
