Welcome to the forum Samuel. Congrats on your new Spatial Audio speakers. I haven't heard those particular speakers, but they garner positive reviews. There is certainly a growing list of open baffle speakers with too many brands to mention. At one point I considered planar magnetic panels for my next system, supported by a Rhythmik Audio sealed sub. Though in the end I concluded that open baffle speakers aren't right for my apartment due to limited space, and an uneven front wall. So I plan to go with high efficiency ported speakers.
