I’ve used Sonic Tools MSS Cabinets here at OGHQ for the past 5 or so years and they have held up great. I'll still go with MSS+ for my personal home garage, but for those of you who aren’t crazy like me and would prefer not to drop $40K on a cabinet array, these are a great option. What I enjoy most about them is their compatibility with the Sonic Foam Inlays.
If you’re bold, you can buy À la carte and track everything yourself, or do what I would recommend doing and reach out to OG Design and let them do everything for you.
Keep in mind the cost to ship these cabinets. They come assembled, so the size and weight make shipping costly. Just to ballpark you, I would say the average $10,000 array costs about $1,500. They come from Auburn, AL. The closer you are to them, the less it will cost.
