I'm planning to add 4 height channels to my 7.2 system, and I'm looking for advice on which to choose. Here are the assumptions to consider: 1) the room is large, has very high vaulted ceilings, is open to another room on one side, and neither in-ceiling, nor in-wall speakers are options. The speakers must be mounted high up on the front and rear walls, 2) My current speakers include Paradigm Signature V6s, V2s, and ADP3s along with SVS subs. Paradigm signatures are no longer in production and they didn't make a model appropriate for height placement. As a result, I know that the 4 new height speakers won't be an exact timbe match for my current system. This is OK with me as long as they are "similar" in tonality, 3) my budget is up to $4000 (not including wiring and mounting), 4) because of the room size/shape, I want to be able to point the speakers toward the MLP, so mouting flush on the wall is not going to work. They need to be compatable with some other mounting solution that can be adjusted for tilt and swivel, 5) I'm using the system for about 80% HT, 20% music. Based on research, both the Arendal 1723 Height S and the Perlisten A2s are on my short list, although I'm not sure how they would blend with the Paradigm signatures. Any recommendations on these or other options to consider?
