It is not the Pendragon tweeter. I have the dragon and it has SB Acoustics Ring Radiator tweeters. The tweeter in the Oriel is a high efficiency soft dome Vifa tweeter. Knowing Eric it is likely very detailed and smooth. It looks similar to what is in the mini-Lore but not certain it is.
The Oriel looks to be like a mini-lore on steroids - since it is 98db and be driven with very low watts. I would also wonder if it has a slightly better bottom end then Lore, since the Eminence driver he selected does not have a whizzer and therefore is not going to play as high in frequency... with that trade off it may roll off differently on the low end??
I know the jump from the lore to pendragon in bass is gigantic... and this woofer seems closer to what I have in the Pens. I am betting this Oriel is equal to Lore but with different trade offs.
