I am selling my house in the next few weeks and will start constructing my next theater in the new house. In preparation, I am looking for some advice/suggestions for new speakers. My current setup is Chase Pro-10's up front, DIY speakers from a Madisound kit (8" seas mids/1" dome tweeter) for surrounds and a SubMersive HP. The Chase Pro-10's have been fine, but I want to upgrade. I have been looking at the Seaton sparks (currently unavailable though), JTR Noesis 228's and the SEOS offerings from diysoundgroup. Size is not really a consideration. The sparks are pricey enough that I would have to space them out over time (same for the JTR's). What should I consider DIY-wise that would compete with those offerings?
