If you look past your list, look no further than the Dunlavy IV-A. They are everything you want and more. They do sonically disappear but visually..they are big.
Which Speaker in the 4-6K Range?
I am interested in buying a pair of full range floor standing speakers that have the following attributes:(1)Sensitivity of 90db or greater. (2)Bass extension down to at least 25-30hz. (3) Solid built quality. (4) Ability to simply diappear and (5) cost about 4-6k. I am considering the Silverline audio Sonata and Coincident Technologies. I prefer the Hales Design Group Trancendence 8 but it costs 10k unfortunately. Please help.
