Decided to get serious so I am taking the plunge & going to get some software & a mic. Problem is which to get? I'll address the mic issue 1st. I remember reading somewhere in older posts that there was a $40 mic that measure real flat & was the best bang for the buck. Does anyone remember where I can find it or what it is? I think it is the Behringer ECM8000. I thought about doing the modification to my RS SPL meter & using that but I would just rather get a the mic. Unless of course the panisonic cartridge WM-60AY modified RS meter measures flatter than the $40 mic. What about the microphone pre-amp issue? I heard the Rolls PB23 for $45 is a good deal. I am lost here though. Do I have to get one? Can't I just plug it into my sound card? If I do have to get one it seems best/cheaper if I just modify my RS SPL meter since it is powered & wouldn't need a preamp. Please advise. Programs & measuring software. I plan to continue to use Unibox & WinISD for box work for the time being. I think both these programs are great & easy to use. Oh yah, the price was right as well . I know there are a few main players out there for xover & measurement work. This is the popular short list that I have come up with. There are a few words of opinion for each: LspCAD, $130: Very popular, great product, total package & comes with with JustMLS measuring software, good price, can be a little tricky for the 1st timer. SoundEasy, $225: A complete package as well, little complex, not as good as LspCAD which is less $$$. Xover3Pro, $90: Easy to use, CHEAP, no measuring software. Winspeakerz + TrueRTA $80: Cheap as well, software not as good as some of the others. CLIO, $600: I think this one goes without saying WinMLS 2000 $80: Just measurements software, no xover program. ETF: Just measuring software, no xover program. If there is anything I am missing or forgot to consider LMK. Look forward to hearing what you guys think about these choices.
