Aerial gets good at the 8b and 10t models, the lower models have too much compition to be a reccomendation. The Vandersteen sub is a great idea with something like Audio Physics Vergo's, Merlin VSM or even Vandersteen- just my oppinion but I have owned the Aerial 5 and 8b and just thought if you are going to spend that much money you should get a more musical speaker.
Experience with Aerial models 6 or 7b
This will not happen soon, but I would like to take as much time as possible on this decision so here it goes. I currently use ML Aerius i with Proceed HPA2. Just moved to a bigger room, ( 17w x 15d w/cathedral ceilings ) and it just doesn't seem to fill the room enough. I am not looking for concert level volumes, maybe a good solid 90db would be fine. I will purchase something local and have been considering the Aerial models 6 or 7b. I want to be able to place the speaker within a couple of feet of the back wall also. Other options would be the new ML Ascent, but that might be a little imposing for the room. Dealer also carries B&W, Vandersteen and Maggies although the last two are out due to the cat factor. Will the model 6 fill the room? will 7b work that close the back wall? Or maybe try the 6 with a Vandersteen sub? I listen mostly to rock and the final bill needs to come in around 4-5k. thanks in advance for your experiences.
