  • What Professional Designers & Architects Dream About
  • Superb Build Quality
  • The Best In-Wall Subwoofer We Have Heard To Date
  • Very Easy to Install in New Construction Homes


  • Global Phase Control
  • Relatively Short 3-Year Warranty
  • Dry-wall Mud Won’t Adherer To Filler Panel
  • Inaccurate Wiring Info In Installation Guide
  • May Be Difficult to Install In Retro Custom Installations


Overall, the SC-IW subwoofers performed well beyond my expectations and erased any preconceived notion that I had about in-wall subwoofers. It rivalled the performance of many good 10-12-inch freestanding box subwoofers making it the best in-wall subwoofer system I have heard or installed to date. I highly recommend the SC-IW subwoofer and SC-1250 amplifier to home owners, custom installers, and designers that wish to maintain the minimalist design trend without performance sacrifice. –Bravo Velodyne!
