Testing loudspeakers?

[mdwight]

PE says that the TESTING LOUDSPEAKERS book by D'Appolito is "not intended for the novice." Well, ok fine. But how are the novice going to learn to test loudspeakers? Where can the novice go to learn the stuff necessary to understand the D'Appolito book?

I don't understand why anyone would write a book only for experts. If you already have the knowledge what do you need the book for? I feel the same way about the LOUDSPEAKER DESIGN COOKBOOK. If you can understand it then you don't need it. One of you guys here really needs to write a good book that takes the novice step by slow step from the very basics of sound to advanced speaker design. Now that book would sell well! The problem with this hobby is that all the books are to simple and don't go into advanced subjects or they are for experts with EE degrees only.

a good calling but probably not profitable

you're talking about taking the novice thru fundamental math, physics, computer literacy, with woodworking skills to boot.

the closest thing yet is Ray Alden's "Speaker Building 201"

since this is not a college course (~$120 book) there is no demand/profit for your request.

You may be right. But I for one would MUCH rather spend a lot on a few good books than spend years of my life trying to figure this all out by doing web searches. I've spent the last 18 months reading this board. I've learned a ton but a series of good books would have been much quicker and I would have learned more.

And I've still learned nothing about mearsuring speakers for x-over design. Haven't even found a single web page that goes into the subject.

I think Hong has some info at his site, but I'm not sure how comprehensive it is.

Dude -
I'm closer to your skill and knowledge level than a guru, but not as frustrated. First get, read, and understand SpeakerBuilding 201. Then get Passive Crossover Designer 6.1. Jeff Bagby has created incredible software for free. People use this and the FRD tools to design speakers that measure exactly like the simulation.

<A HREF="http://audio.claub.net/software/jbagby.html">http://audio.claub.net/software/jbagby.html</A>

Also Speaker Workshop has a great free-form graphical crossover design tool.

Good luck, you don't need 2 semesters of college to master this. (Although I would have liked that)

regards,
-Don

I understand your frustration. As I said before this is not a polished subject (no demand). I started several years ago and still find it a pain in the !*" to learn something. I do have a comprehensive technical library (AES anthologies, Testing Loudspeakers, LDC, Bullock on Boxes, High Performance Loudspeakers, Acoustics (Beranek and Everest), Music Physics and Engineering (Olson), Leach's Introduction to Electroaucoustics and Amplifier Design, etc., etc., ...

They all have special information in each that you must gleen.

If you want to get into measurement I'd suggest getting SE(SoundEasy) ~225 plus a Behringer ECM8000 ~60 with calibration another ~35 and a Behringer mic preamp ~60. I use a Delta 410 sound card ~100) The mic cables, stand, probe cables ~100. Get John K's SE guide ~15 and you'll have just about a best pro bang for the buck as you can get.

One thing though...You ain't gona learn this tons of new information overnight. No pain No gain.

Best Regards,

Mike

I agree that the reference material available to DIY speaker builders is limited and incomplete. I have the Loudspeaker Design Cookbook and Testing Loudspeakers. I built my first set of speakers using the LSDC and in hindsight realize how many "no-no's" I had in that design due to a lack of knowledge. I have a master's degree in EE and can understand the material but still found that the content of the book was a bit lacking and allowed me to make those mistakes. I got the Testing Loudspeakers book later and found it to be helpful in certain sections and will sometimes reference it for a few formulas. I think that even if you aren't an engineer some of the basic concepts regarding measurement techniques can be easily grasped.

I'm pretty certain that speaker design can be taught in a way that isn't math intensive but still presents a level of understanding required for an optimal design. I actually started writing a book like this based on the information I've gathered over the past 10 years. However, writer's block and lack of confidence with certain subjects has halted my progress. Crossover design is the primary area that is not covered in enough detail anywhere. I consider myself to be an advanced crossover designer and understand the importance of the crossover but most of these skills were learned from experience. I know there are non-mathematical ways to teach crossover design but there is still an art to tweaking a crossover that can only be gained through experience. However, simple concepts like understanding that an inductor passes low frequencies and resists high frequencies (opposite for a cap) can be presented along with examples of crossover circuits and illustrations of how changing different components alters the response. The bottom line is that I know that most of the required knowledge for designing speakers can be learned in a somewhat non-technical manner.

My motivation has been low lately... I still have to finish the web page for my latest project which I finished over a month ago. My only advice is to buy some books and get as much as you can out of them but the rest will have to come through the internet and/or experience. These forums can be a great place to learn and I would have to say that I've learned much more on these forums in the past 10 years then I would have ever learned reading speaker design books. You can even post a question here when you get to a complex subject in one of the books. Most DIY speaker designers are pretty good guys and it is very often that an apprentice who asks a lot of questions eventually becomes someone who can answer questions on occasion so it is a neat way to pass on information.

Well then, ignore what they said and buy the book. I have never let anyone tell me that a book was over my head. I think that's up to me to decide. Don't you think?

Well said Roman and I completely agree about how one learns best from experience. I think the single most important event in my loudspeaker building past was when you invited me over to your house and showed me how to take measurements. Listening to all your speakers was really inspiring as well.

I'm sorry to hear you haven't had much motivation for loudspeakers/updating your webpages etc. You really have a lot to offer the DIY community and I think a book or a step by step manual about how you go about designing speakers would be very helpful for a lot of folks.

There is always something new to learn in this hobby. Lately, I've found myself going back to older designs and updating the crossovers with new information I have learned. I keep asking myself, what on earth was I thinking when I put that part there, when it definitely isn't optimal. But, that is what learning is all about, and if I wasn't improving and making important changes in how I go about designing speakers, I doubt it would be fun anymore. Maybe that is the point where you are at now, you've kinda been there done that, so to speak. My advice would be to try something radically different. And see what you can come up with and "reinvent."

Talk to you soon,

I found Doc Joe's book very well written with the various concepts explained in easy to understand language. Certainly easier to follow than thn LDC. I'd suggeust you buy Speakerbuilding 201 as well, presuming you are a just starting out.

[Paul Carmody]

If you want to find a book on how to go on the all-watermelon diet, or how to create a website for your dog, you'll find your local bookstore has loads of offerings. If you want to learn how to design, build, and test a set of loudspeakers, good luck even finding a book at a bookstore. As far as I can tell, there are about 4 books on the subject, and at least one of them is essentially out of print.

It's hard to say why there is so little published info on the subject--maybe it's just a really obscure hobby, and it simply takes too much math and woodworking talent (not to mention a good ear) for most folks to just "pick up in a weekend."

10-12 years ago, I really wanted to get into this hobby. So I went to the local library; they had David Weems' old books, and the LDCB. Weems' stuff all called for Radio shack parts which were unobtainable, and the LDCB just completely overwhelmed me. Since then, however, the internet has become a wonderful--and easily accessible--place for small interest groups to share vast amounts of information. If it weren't for the internet, I don't know if I ever would have really made a real attempt at this hobby.

The internet was really the catalyst I needed. It had designs that were current, plenty of photos, and assistance when I needed it. Then, once I felt some success at building a proven design or two, I wanted to know more more MORE. So I read Loudspeakers 201 and LSDC, and was more receptive to the information. But still, I must say that what is in that books is only so useful. Most of what I really know and understand about speaker building and design came from experimentation, and having gurus to ask for guidance at critical points. It's almost like learning an instrument; you can read about technique for years, but you're not going to be able to make much of a sound unless you get your hands (lips, whatever) on that instrument and play and practice.

Personally, I really wish there were more books on the subject of loudspeaker building; but for the most part, it's a black art. I don't know about other people, but I would LOVE a book that discussed the subject on a practical (maybe even subjective) level, rather than feeling like a calculus or EE class. (And I suppose that at least half of the speakerbuilding websites out there work at that level (and for guys like Roman, Curt, Zaph, Wayne J, Lou, and Andy, I am eternally grateful)) If my level of knowledge ever got high enough, I would love to write such a book... because, yeah, that's the other tricky part. In order to write a book, you really gotta love to write.

Me? I'm in love with the sound of my own writing voice ;-)

The guy is a legend and everybody says the book is great. BUT, I would suggest starting with LD cook book or just info on the internet and build a simple, cheap 2-way with a simple xover, 1st or second order filters, and tune it until it sounds decent. Much more fun that way. I don't use testing gear and computers, and I've been making my own, great-sounding speakers for 15 years. I can design by experience with a pocket calculator. I do actual DIY. You don't need to test if you have a decent ear.

Someday I might start an actual DIY Speakerbuilding site. In the last ten years, the hobby has been completely consumed by computer-philes and nobody even bothers to design their own xovers anymore. You just stitch together drivers, and inductors and caps and resistor...it's not that hard.

What's to know? You get a mic. and a signal generator and a PC application to process it.
Go ahead and get the book. But you don't need it...

A couple of things that might help. I put together a Manual for Speaker Workshop that you can download at <A HREF="http://www.audiodiycentral.com/">http://www.audiodiycentral.com/</A> or at <A HREF="http://www.ClaudioNegro.com">www.ClaudioNegro.com</A>. In it, there is a lot of good information that you may find helpful. It is written to accompany the free Speaker Design Software, Speaker Workshop, but you can ignore the portion that refers to Speaker Workshop if you want and play with the rest of it and with the accompanying sub-programs and excel spreadsheets. Claudio has really good information at his site and Jeff has written a really nice piece that is also at the link, below.

Speaking of Excel Spreadsheets, another great way to learn is to download from the FRD Consortium and most recently, from <A HREF="http://audio.claub.net/software/jbagby.html">http://audio.claub.net/software/jbagby.html</A>. You can take frd files and zma files that can be found at PE or at other sources (some even included with some of the FRD programs) and play with design until you feel comfortable. You can learn a lot, just by looking at the results.

Don't expect to learn this all, overnight. In fact, it is the journey that is enjoyable; the destination point is always changing.

Good Luck,

Jay

As an aside, I really did not mean to leave out the several other great websites such as John K's, Roman's, Dave's, etc. As you hang around the boards, you will pick up on many of them.

HEY JAY,
I've been using SW for some time to play with raw imported frd and zma files to practice my x-o skills. But I'm completly lost on how to use the measuring sections of it. I've tried many many times to download your manual but for some unknown reason my computer does not like that file. I've tried to download it like half dozen times over the last year. I've got no idea why it won't work for me. Jay, is there anyway to get your manual by another means? Is it printed in HTML anywhere?
One other question. Where can I go to ask question about SW? Last I saw the SW forum was all but 6 feet under.

[jmb]

Nelson and Claudio and others still visit the SW forum every so often. If you can't download the Manual from AudioDIYcentral, try <A HREF="http://www.ClaudioNegro.com">www.ClaudioNegro.com</A>. It should download okay from there. As a last resort, depending upon your Email capacity, I could email it to you section by section.

You could also post at this forum, DIYaudio.com, or at Madisound. On occasion, you will get timely and accurate responsiveness. Roman has used the program frequently.

I don't offer my own input routinely only because there are many times where I will go weeks without visiting due to other obligations (my medical practice, my family, my sleep - when the opportunity presents itself). If I do see a question, though, I will do my best to respond.

If it wouldn't be to much for you I would really like it if you could email it to me in sections. But I understand your busy so no hurry.

I just read through Claudio's site. Very nice and easy to follow. Maybe this isn't as difficult as I thought it would be. :)
