Wanting to make my own crossovers for home speakers.
Answer
When it comes to designing and constructing the highest performance passive multiway crossover networks it is ABSOLUTELY ESSENTIAL that the designer utilize the complete complex transfer function, as precisely and accurately as possible, for each of the transducers being used in the loudspeaker. Failure to do so would fall far short of what one would truly justify as âhigh endâ or high performance. Without question, the best, most effective and efficient approach is to use crossover design software to synthesize, optimize and model your crossover network designs; an excellent investment if you will be (or expect to be) heavily involved in designing and building high performance loudspeakers. Through an iterative process such software will generate a complete schematic including individual component values from which you produce the component layout for use with either point-to-point or printed circuit board construction.
In addition, in order to achieve the most accurate modeling and synthesis you need to use a loudspeaker measurement system to measure the transducers you will be using (in their enclosures where applicable and after lengthy break-in) and export the measurement data from the measurement system directly into the crossover network design software running on your computer. Though using the measurement system is the best approach to achieving an optimal crossover design it is by no means a necessity - but highly recommended nonetheless. If you choose to use the combined approach then you need to make sure that the measurement system is compatible with and/or specifically supported by the crossover design software.
When it comes to crossover design software two of the most powerful and popular packages are LEAP (Loudspeaker Enclosure Analysis Program) from LinearX Systems and SoundEasy/EasyLab from Bodzio Software Pty. Ltd. With respect to third-party professional loudspeaker measurement systems there are many from which to choose. You would need to determine which will best serve your needs and fits within your financial budget. Links to the Websites for both companies can be found in the Google Docs resource listed below.
That said, there is a third, less desirable option if youâre prepared to compromise a little by foregoing the opportunity to fully maximize your loudspeaker crossover/system optimization in an effort to reduce the your short-term costs: you can, depending on the drive units (and enclosure) that youâre using, use the Leap Crossover Design Service from Madisound Speaker Components. (Madisound is not the only company to offer such services but they are the first that comes to mind.) Again, you will find a hyperlink to relevant Madisound Webpage in the Google Docs resource below.
Randomly combining preassembled crossovers with assorted drive-units is not a recipe for success IF you are truly after a high performance (or âhigh endâ) loudspeaker. On the other hand if you purchase a complete turnkey loudspeaker kit, i.e., drivers and crossover â with or without a loudspeaker enclosure, then you have a much better possibility of constructing a reasonably high performance loudspeaker; the performance of which will depend largely on the kit design, component quality, construction and the producer of the kit. In other words, if a basic loudspeaker kit is carefully designed using the tools Iâve mentioned above then you are reasonably likely to end-up with a loudspeaker that performs well. This is a good option for a first-time (or one-time) loudspeaker construction project, however I personally find it far more enjoyable and rewarding to design optimized, high performance crossover networks for driver combinations and enclosure designs of my choosing rather than someone elseâs.
I hope you have much success with your loudspeaker design and construction endeavor.

What website to build the best speakers?
Cody Gordo
What is the best website to build home speakers, money is no object. So, don't hold back.
Answer
If money were really no object no, you would not "just buy speaker". You would instead have them custom designed, built and calibrated. If you want to build your own then you can do pretty well without spending very much at all, about $2000 to $4000 can set you up fairly well.
The Linkwitzlab "Orion" kit is one good option, http://www.linkwitzlab.com/DIY%20products.htm "The completed speakers cost around $3800, without power amplifiers". Or, you can buy the Orion 4 fully assembled starting at $14,750. http://www.linkwitzlab.com/Wood%20Artistry%20LL-home.htm For putting together a 2-ch system this speaker is a very good option.
If you are more interested in home theatre then you may want to consider the CBT-36 kit from Parts Express... http://www.parts-express.com/cbt36/ This speaker will be more dynamic than the Orion making it a better choice for home theatre.
Parts Express also has a number of more conventional kits... http://www.parts-express.com/wizards/searchResults.cfm?searchFilter=&srchExt=CAT&perPage=25&sortBy=0&layout=list&page=1&srchPrice=&srchCat=769&srchMfg=&srchPromo=&srchAttr=
If you want to design and build something on your own then you will want to seek advice from the DIY section of the AVS Forum... http://www.avsforum.com/avs-vb/forumdisplay.php?f=155 In order to complete your own design properly however you are going to need to invest in acoustic measurement equipment and CAD software. http://www.parts-express.com/pe/showdetl.cfm?Partnumber=390-790 and http://www.ijdata.com/
Most of the hard core commercial speaker fans are simply not familiar with what's possible in DIY nor do they understand the limitations placed on speaker manufacturers. They believe because these companies specialize in building speakers that they will be better at it than you can. If they didn't have their hands tied behind their backs this might be true. They can not research the Audio Engineering Society Journals and use any technology they like unless they pay royalty to someone. As a DIY'er building speakers for your own use in your garage you can use and combine any and all known technologies. Also, a speaker companies primary goal is financial growth, not to build the best possible speaker. In fact, the speaker companies that make the most money build some of the worst speakers. (ie...Bose) It's simply not profitable to go to the Nth degree on improving sound quality. So as a DIY'er you are free from marketability restraints and you have access to a much larger knowledge base than any single manufacturer. This doesn't mean you automatically get a better set of speakers by DIY, there are plenty of poorly designed and built DIY speakers out there but it does mean that you have virtually no limitations. You have to put fourth a lot of effort to insure good results.
