Question for those who know about open baffle speakers...

Last summer I heard a pair of DIY speakers and I was blown away by their transparency and their image ... They we're open baffle speakers with Scanspeak components powered by a mini DSP ... I did some research and find out that this was a design inspired by the Linkwitz LX 521. After reading quite a bit on the subject, I became interested in some manufacturers (Pure Audio, Spacial Audio, Tri-Art , ...) and noticed that some use dual concentric speakers. I know this kind of speaker well since I've been using Altec 604s for years. As open baffle technology is largely based on the principle of dipole speakers — speakers that emit sound both forward and backward — I wondered about the use of dual-concentric speakers. Indeed, as soon as the high-frequency driver comes into operation, there can no longer be any question of dipole in the case of a dual concentric speaker since the driver's back is closed. That leads me to think that these speaker's won't have the qualities that impressed me so much from those I heard last summer (which were dipole) What do you think?

I have not heard open baffle speakers that use a concentric done driver like this, but I I would share your concern. They could sound very good though. I have heard speakers that were partially open baffle but used a horn upper-mid-range/tweeter that sounded fabulous. 

Also, check out GR-Resesrch. I am using their NX-Otica open baffle speakers with their open baffle servo subs and they have excellent detail with a huge soundstage.
