I just picked up my 2025 ST 2 weeks ago. I wondered the same thing. I asked to listen to both systems, one on an Active line and the ST I purchased. It was a night and day difference. The sound quality fill and over all power difference was noticed quickly not only by myself but my wife also. You will want the 14 once you hear the difference. Go to the dealer and ask to test drive an active to hear the difference.
