help picking bookshelf build

[cdfac]

An acquaintance I'd purchased from before offered me a deal on his raw driver collection. I'd like to hold onto a few of the more interesting pieces and build a 2-way bookshelf speaker out of them, but I need some ideas/validation. Other than established kits, I'm new to real DIY speaker work.

Tweeters:
Dynaudio D28AF
Dynaudio D21AF
Vifa D25TG
Vifa H25TG
Polydax DTW9X8T25

Woofers:
Dynaudio 17W75XL-8 (6.5")
Vifa P21WO-10 (8")
Polydax MTX20X25RSN (8")
Polydax 110-1095 (5")

I think I'm leaning toward using the the D28AF and 17W75XL together, since that was essentially a kit that Dynaudio offered back in the day and there are some crossover designs out there to be used. They would also basically fit into the Dayton premade bookshelf cab you can buy from Parts-Express (I'm not a good woodworker). If need be for another design, as long as there's a knockdown CNC cut cabinet available in the right volume, I can do the baffle cutouts.

A proven design, with easy to source cabinets, seems a winner to me. Building a custom cabinet can be difficult or expensive if you don't have the tools or skills to DIY it.

The d28f is a nice tweeter, smooth and doesn't wear on my ears. And the dynaudio woofers are very very nice, don't let the size fool you, they will punch.

I would very highly recommend good strong cabinets, that 40hz fs is very real. Bass reflex was the intent iirc.

I stuck with my easiest plan. These PE cabs are tuned to 36 or 38Hz, I believe. This is how it looks with the drivers just dropped in, I'm pretty excited! I'll dampen the interior with some acoustic foam, if I still get a lot of resonance I'll take additional steps. Crossover parts should be here soon so I may be listening to these by tomorrow night if I can get enough time to wire things up.

I've spent so much time listening to these that I never followed up on this thread. I ended up using the following crossover design (from a DIYAudio thread) since the D260 is close enough to the D28/AF in the relevant respects.




They are subtle and delicate when called for, but they also sound bigger and far more expensive than their price tag. If they ever get kicked out of this particular setup, they are definitely going to stay in the family!
