Thanks. That's quite a range of box volumes and tuning frequencies to play with. One thing I've learned is that it's easier to make an overly large box smaller than it is to stretch one to make it bigger:)Wouldn't it be fun next May to have several Studio One Pi tower volume and tuning variations available for a side-by-side comparison with each other and with the standard Studio One Pi enclosure. I'll volunteer to bring the 1.3 cu ft version.
