Probably the tweeter height would be my biggest concern. It might be way too low.
Bookshelf Speakers Sitting On Dual Subs?
I have a couple excellent subs - Elac Adante 3070 - which have pretty effective DSP. I'm thinking of buying the Dutch&Dutch 8c (also DSP). The Elacs are rock solid. I'm thinking about placing the 8c on IsoAcoustic stands on top of the Elacs so the 8c is even with the front of the Elacs and separated by the Iso stands: running the DSP for the subs and then the 8c. Any real drawbacks to this set-up?
