Woodgab,
Thanks for offering your comments. My reflections will follow.
-You do not strike me as being entirely comfortable commercializing your product.
You are very correct. This is simply because I cannot build enough cabinets nor can I garuntee time at the keyboard. My full-time job and family certainly come before speaker building. My work will assume a different character next month when I have to deploy for 1 week periods. I will not be accessible during these times. This is obviously not condusive for someone operationg a "commercia" entity. A bad reputation could/would certainly follow.
-You may want to reconsider the place your religion has in the profile of your business. In your conceivable market, beliefs differ quite a lot and references to faith can be alienating.
Hmmm, I am bothered by this

. I think it is somewhat sad that expression of religion is publicly frowned upon. While ontology, philosophy, psychology, sociology, have some very good eplanations about what should be, I believe that religion is an extremely postive catalyst for behavior. Sure, the naysayers will cite the problems with extreme radical's, but what about the other 99.99% of people who benefit, and who's societies benefit, from their religious practice? I believe that if anyone is "alienated" by discussion of religion they really needs to take some time for serious introspection.
In this regard, I have met people who are uncomfortable discussing religion. These folks aren't common. Among these few people it's my unqualified assessment that these people were/are very uncomfortable with who they are. There was more happening "under the surface" than what appeared superficially. However, in all these people, none of them were personally bothered by any public declaration of religion.
I really haven't met anyone who actually was bothered by public delcaration of religion. I believe that 80% (my crude estimation) of people in the United believe religion is essentially positive. Approximately 20% of folks don't care about relgion. However, there is about .1% of people have successfully lobbied & litigated religion out of the public. This mystifies and saddens me

.
Are you alienated by my confession of Christianity?
Do you actually know people that wouldn't do business with anyone professing to be a Christian?
As a history lesson... in 1925 Clarence Darrow argued that anyone who would teach Creation to the exclusion of Evolution in school is certainly a bigot. I agree. Sadly, today the opposite argument is gone. Evolution as taken-over the curriculum. Creation is nearly extinct in public schools, and the public declartion of religion is slowly dissappearing.
Years ago I did a crude study correlating the relationship between violent crime, and the percentage of schools in the USA that said the Pledge of Allegance. I am smart enough to know there are other indicators of good religious teaching, but the correlation was frightening. As the Pledge of Allegance was pushed from schools from @1955 to 1980 the occurence of violent crime rose @250% per capita. Again, there are many other social indicators to cite, but I believe this one cannot be ignored.
Please understand that I am not attacking you. These are simply some of my personal sentiments on this matter.
If I really like the OW1 and Seas drivers, does there have to be a proprietary premium on the XO, or will there be other free XO designs from the expanding internet community?
Good question! There are a couple of answers. I don't suspect anyone will have the gumption to copy the 1801 crossover and publicise it. Certainly there are many more appealing crossovers to copy. Many commercial products have a much better repuation than the 1801. However, am honored that you place the 1801 in a category worthy of this.
I will not make the 1801 crossover public domain for the same reasons that Kharma will not make their crossovers public domain. There certainly doesn't have to be a "proprietary premium" on the crossover. However, continued effort/business depends on this. Further, I really don't think "premium" is a fair word choice. Those folks who have built the 1801 and compared it to speaker costing 5-20x$ know the inside story on this. The general sentiment is that the 1801 is an extreme bargain in hifi. Paying for the 1801 isn't a "premium", it's a "steal". However, if I charged $2500 for the kit and $5k for completed speakers, the 1801 would be appropriately priced. If I charged $5k for the kit and $10k for completed speakers.... that'd be a "premium".
I have built several designs using 8" drivers that could very easily be public domain. I even built a very good 3-way for under $500. However, I really don't think any of these designs are worthy of a customers time in the cabinet shop. The 1801 remains a much smarter project due to the size of the cabinet, the complexity of the project, the total project cost, and the sound quality obtained.
From my keyboard, I don't know whether this OW1 application is better, worse, or sufficiently the equal, of the 1801b: http://home.twcny.rr.com/cnydga/asterion.html . Suffice to say, it seems well thought out.
Rick is much better with crossovers now than in the early years. I am sure his implementation of the OW1 is just fine. If a guy wanted to spend less on the midwoofer, live with a decoupling curvalinear cone and simple motor, the Vifa driver is a smart choice. Personally, I prefer paper for a flexible curvalinear cone, but this a personal bias. I must admit not having a complete answer about all curvalinear cones, but did see a comment from a SEAS engineer concerning the reason for the midrange droop of the new L18 SEAS drivers. He said this was because the inside of the cone decoupled with the outside of the cone. The result was a midrange response droop when compared to the L18 with the straight-sided cone. Indeed the straight sided cone had a more severe resonance, but the cone was more rigid in the 2khz region. I suspect the same is true with the vifa wood cone. The curvalinear shape makes life much easier on the crossover designer, but does flex in the midrange. Ya' can't have yer' cake and eat it too.
Also, I must comment here that paper curvalinear cones can and do sound very good with old rock-n-roll. IMO, nothing is better for old rock-n-roll than some big JBL's!! I have also heard that old Altec speakers sound incredible on this type of music, but have not heard this personally.
Have you considered a high end inwall ?
Honestly.... no. I haven't given, much/any thought to the 1801s and home theater. This is simply because HT source material is generally average quality. I think some good paper cones are the smart choice in this regard. Sure, stiff cones will provide more resolution, but this isn't always better. Jim Salk (
www.salksound.com ) and I agree on this matter. He developed a very good speaker for home theater with a crossover for in-wall applications.
Or, for that matter, are there other designs kit buyers will migrate to on the basis the XO designer's talents.
I am really not sure what you mean. Could you explain further?
