The L brackets are an option to mount them under your desk. If you leave it in a permanent location. The video was great!
One quick note. If your driver has av pole, make sure not to have the pole blocked when testing. I just use a few small blocks to elevate it off the ground.
Yeah, that little driver is sealed in the back but I am aware. I hadn’t thought about UNDER the desktop. I might just do that. Also, in other news, just ordered the Ultimax 18” sub for cyber Monday! That is going to be fun!!!
