Jeffery,
you might want to try spikes or feet with your speakers. I don't know about the Ulfberhts but it definitely improves the sound of the DI's and other Tekton speakers. Without something filling those threaded holes bass escapes from them making them slightly boomy. I learned that by leaving the spikes out in order to position the speakers easier until I found the best location for them. When I told Eric I was doing that he said not to as I wouldn't get the proper bass response without the spikes and therefore wouldn't be able to position them properly. Screwed the spikes in and the bass was much better.....so as good as your Ulfberhts sound now they just might sound even better with those threaded holes filled.
