I didn't want to hijack the spreadsheet synergy thread. So, I'm new to speaker building. If your like me, then sometimes noobs get on your nerves too. I'll try not to annoy you guys too much. Why am I here? Cuz Danley speakers sound amazing. First time I heard them was outdoors. It was an SM96 over a pair JTR Growlers. I was floored by the clear sound. The bass was awesome too. It so happens that I can't afford a pair of Danley's right now. And since I like DIY, I would rather build. Although these are tough to figure out. I'm looking to do all eminence drivers: Highs x1: NSD 2005 (1-inch compression driver) Mids x4: Alpha 3-8 (3-inch driver) Lows x2: Alpha-10A (10-inch midbass driver) FaitalPro also has some interesting drivers I like. I downloaded Synergy Calc V5. I need to become familiar with all the terms. But I couldn't find any fields to input the size of the drivers. Driver size will affect the final size of the horn panels. Am I missing this somewhere?
