The 228 is not designed to be a floorstander. It is expected that it will be used with a sub as it only goes down to 70 hz. The Pendragon achieves similar specifications by using pro woofers and 3 tweeters to keep up with them. Jeff uses a compression driver and horn that do not need multiples to keep up with the dual woofers. While I have no doubt that the Pendragon is a nice speaker, it does have the drawback of being vented to the rear which means it must be placed away from the wall, limiting its placement options, especially for people who want to use it behind a screen, and if used with a decent sub (JTR's sub offerings are far superior to the subs that the reviewer of the Pendragons owns), much of the low extension would be wasted. It also does not have the controlled directivity of the Noesis line.
My guess is that Jeff has a smaller markup than the manufacturer of the Pendragon as the compression driver probably costs more than the 3 tweeters used and that the Baltic Birch plywood is more expensive than the MDF that was likely used in the Pendragon, so you are likely getting more speaker for your money with JTR.
In the end, it would probably come down to personal preference. Any comparison based on specifications is purely academic. Since there is only one pair of 228's in existence, it is certain that no one has compared these speakers in a controlled setting, so who knows how they would stack up.
