I didn't get the part of adding the inserts either, especially when the slot on the bars is wide enough to accommodate 3/8" and M10 size bolts, at that point you can pretty much work with any stock insert the speaker manufacturer uses, so why drill and use such small bolts. I did not have to go to HD, my business is selling nuts and bolts and all other types of industrial products and safety, so I just grabbed them outta my store. SQ improvements idk I can't really say, I thought at first that the bass was weaker, but I am pretty sure now that it's just better blended, I had pulled the speakers out 7 additional inches now that I felt confident they weren't going to spill over if bumped. The front baffle went from 25" to 32" off the back wall. I wasn't really looking for it to sound better, to be honest, with 3 kids I wanted to make sure that the speakers stayed upright when they get to rough-housing. Perhaps the fact that I feel confident enough now to pull them further out and better balance the bass and open up the sound stage are the improvements I needed.callas: any improvements to SQ by chance?
I don't understand the drilling+wood inserts advice from the seller. WTF. From the pics, I thought installation only involved the bolts. Did you have to go to the Home Depot to get the right bolts? Seems like it was pretty easy once you ignored the seller's advice.
