A pair each of Focal 7N515 midwoofers and Dynaudio D-28/2s tweeters. I know the Dynaudios are highly regarded (or at least were in their time), and the build of the Focals suggests good quality. I managed to find PDFs of the manufacturers' specs for these, but I could not find documentation of any projects using them. Does anyone with experience with these (or drivers from the same line) have any comments that I should consider before embarking on a 2-way design with them? Specifically, idiosyncracies of the drivers, harmonic distortion plots, qualitative evaluations, suggestions for crossover points, anything I haven't thought of.
I guess my greater concern is for the woofers. How painful are those rounded-square frames going to be to countersink? How do I get bass out of woofers with a QTS of 0.2?

Thanks Scudinc - have a pair of the D28's, only used them for a year or so, been sitting on the bench. The data sheet might come in handy someday.
I bet the ferriofluid is about gone about now in the D-28s. I took some other similar drivers that were bought back about the same time and checked recently, not much left in them.
