So I've always noted a huge difference in sound from sitting on a couch to sitting in the floor. My speakers a front bottom port , I assume this being a factor in the fullness of the sound. I decided some plinths would be a great way to not only give me more stability but increase the overall height and give me that fullness I experienced, grounded in the lotus position, but comfortably perched upon my layers of insulated coils and soft dacron. I opted for something more financially reasonable.. Thinking if it was an amazing addition I'd spring in the future for some pretty polished marble or granite slabs. For now I opted for cheap and accessible. Home depot.. At 42 lbs a piece 16x16x2 I stacked 2 of these using amazing goo in between for a bit of a flexible seal. Coated with spray adhesive I then applied a gray felt like fabric to give it some shadows and texture, tucked corners.. Concrete drill bit to nylon threaded receptical and in goes the spikes. Trim it up and dam... Sounds great.. Full..Clear articulate presentation.
