Hi,
I have a AV123 sub sitting directly (no spikes) on a hardwood floor which is above a crawl space. Any ideas for something I can put under the sub for better bass? It would need to be something very unobtrusive as it is in a new addition and the wife just barely tolerates it as it is. I had sorbothane footers for a ONIX DAC and I put a couple of them under front of sub (misplaced others when DAC went into storage) but I'm open to other ideas.
