Thank you all. I really love 1723 2S and all my 1723 setup. Subwoofer able to produce something special. Many other subwoofer rather sound one note bass compare Arendal subwoofer. I’ll try it in my stereo system. I”m sure 1723 2S will outperform my two REL B1. I have a plan to add second 1723 2S one day to handle both HT and stereo system. All my stands are diy.
