And I really need to add a bunch of new stuff to the website. It's coming....
While you're adding to the site Danny, think about including the OB/Dipole Sub in the OB Series category on the DIY Kits page. Guys over at Audiogon and the Planar Speaker Asylum still tell me they can't find the sub when I recommend it to them. I explain that the Sub itself, as a product for sale, is actually not listed on the GR Research site, not pictured, described, or explained. That they have to go to the Drivers page, find one of the OB woofers, look at the diagram of the H- and W- frames, and put it all together in their head.
The OB/Dipole Sub is listed on the Custom Installation page on the Rythmik site, with only a brief explanation, but again no pics, and no discussion/reviews from owners/users. It's confusing to would-be purchasers! The Sub certainly deserves it's own page/listing---even a single picture would go a long way to making the design understandable, and a full description of the Sub would answer all the questions I get. I can't tell you how many times I have described and explained it all!
