Hey all! Little brief history, Spent 2 - 3 years as a teen learning everything I could online and in books about sound and acoustical engineering. I even have read the loudspeaker design cookbook cover to cover several times (AMAZING Book - READ IT if you never have!!) Needless to say Being the budget consious kid I was, I learned everything about how to properly install and tweak car audio and home theater systems. Due to my limited budget, I could never take the next step into Real Time Analyzers. I am now 23, with a few thousand in play money for two big projects: - Build a new home theater system (Dual 8" mids, 2 silkdome tweets per front L/R, MTTM configuration and single 15" subwoofer) - moderate 4-way SQL budget car audio system (2-way componets up front, 8inch midbasses in rear, ported sub in trunk, 30band eq for fine-tuning system) Obviously i need a real time analyzer for all my experiments (i'm still learning about acoustics, and a little rusty on some of the math) But i'm not sure which way to proceed. What are your thoughts on those simple Hand-held RTA's - the ones that give you a general idea. Would those be sufficient for tweaking a system and testing a system's performance. Or would it be better to go with a tabletop RTA like the Rion SA-25? Any advice for a newb? I have time to learn how to use em - so thats no worries - but I want to make a purchase (under $500) for either a new or used RTA. And i want to make the most out of my money. Thanks!
