I'm not an expert in this. You can ask others. I live in a townhouse. The speakers pictured below in the other threads are located in the living room which also has a high ceiling. It gets really loud. I can turn the volume all the way up to 10. The onken enclosure i have isn't optimized for the DCA. Volume capacity is only 13.28 liters. Planet10 mentioned it should be around 20.I'm a fan of Nelson Pass amps too. My other project is an F2 car amplifier to drive a DC Gold 9.5R single driver.
