  • Question From A FIRST Time User

    I just set up my new home theater after I became too disabled to leave my house. Figured gaming and watching DVD'S was better than completely walking away from life...I now game all day & watch DVD'S, I am TRYING to set up the most complex new receiver I ever saw! My head is spinning and so my journey into trying to custom calibrate and explore all of this has now begun. I was going to buy an $18.00 SPL cheapo meter at Amazon and as I read reviews, stumbled upon THIS mic and the others like it. I downloaded REW and TryRTA, Room Calibrator and a couple of other programs I found. Now, I sit here and with my iPad I used a free (junk I KNOW) to set all my speakers to equal from my recliner. Then I sit and read endlessly all I can, probably over a thousand threads the past 2 weeks and I am 100% lost. I look at all these graphs but have NO idea, what I am looking at, or for? Is there a source, better yet ANY form of video that shows and explains these programs and how you utilize or translate these graphs into useful data I can understand?

    As I understand it, these programs I got like REW (kind of my favorite even though I have NO understanding of what the graphs mean) can not in any way help me do my set up for my new 5.1 system. But I think it is as good as it could EVER be it sounds so perfect. Actually now a 5.2 with an old Polk sub I added against advice from some over at the AVS forums:-) I understand, if correct, that these programs will just let me SEE how I have done? That would be wonderful IF I knew what it is I am looking at. Before I change directions and forget buying a cheap OR very nice and expensive CL-140 or CL-150 and go this way with the Dayton, I want to know I will somehow find a way to know what it is I am seeing. So where can I go, what can I buy to learn? I love the graphs, leaned how to read & understand the stock market long ago so how do I lean this? As I understand it, my new Dayton (or other brand) mic will act as an SPL using REW and the other programs? I tried an old mic I had from the 1060's and it worked! (even though I STILL can't sing...).

    So is there a book, a website, a DVD or something I can find to educate myself as to what I am seeing with all these complex graphs? I would like to know if it is worth the investment to know what I have already done with this method, or just spend the money on a nice SPL to fine tune what I NEED to do. I will somehow end up doing both since that is all that make sense. Just that poverty sucks. If anyone can point me and my new shiny wheelchair to a direction of learning, I'll owe ya a beer and my undying gratitude! I'm gonna learn this stuff, somehow, someway ,

    Hi Mike,

    This may not be entirely helpful, but at least you'll know you aren't missing anything obvious. I have not found ANY book that gives the basics of measurement and room acoustics for the home listener. Some books are more general and occasionally touch on a few points of acoustics (Robert Harley: Complete Guide to High-End Audio), some are for acoustics professionals and too technical (Alton Everest: Master Handbook of Acoustics), and some have collections of tips for sytem setup (Jim Smith: Get Better Sound), but not much about acoustics in a quantitative way.

    I would LOVE to find a book that goes through basic measurements for the home listener/viewer.

      The two pdfs are a good start. The book is great, but I think you could pass on that for a little while. I have found the manuals for measurement software are a great place to get good info. If I were you I would download the manual for ARTA, Praxis, LMS, SoundEasy, CLIO and what ever else you can find out there.





      Testing Loudspeakers BookThis book is an invaluable reference for the dedicated speaker builder. Not intended for the novice, it covers in-depth driver testing, low frequency system electrical impedance tests, frequency response acoustical testing of single and multiple drivers, and techniques for deriving Thiele-Small parameters using both analog and PC based methods. Written by Dr. Joseph D'Appolito, contributing editor for Speaker Builder magazine. He also pioneered the extremely popular "D'Appolito" woofer-tweeter-woofer driver configuration, seen in many successful loudspeakers systems. This soon-to-be-classic clearly explains the proper way to acoustically test and measure a loudspeaker. If you own "The Loudspeaker Design Cookbook" then this book should be the next addition to your technical library. 174 pages. Copyright: 1998.

        Hi Mike,

        The SPL Meter app on your ipad should be enough to balance your speakers. The receiver should have a setup menu that will help you with crossovers and stuff. If you tell us what receiver you have someone here can help. BUT if you are happy with the sound you have, you may just want to go back to the movies and games and not mess with further setup. If you want to learn to get new knowledge, that's fine too.
