Life After Your Magnepan’s

I started my love affair with Maggies in '86 with the SMGA's. The transparency of the sound really wowed me and still does. In the early 2000's I moved up to the MG12's in a 16' x 23' room and, though they were an improvement, they just didn't seem to have the oomph I wanted.

When I moved up to the 1.7i's, I realized that, even with the Son of Ampzilla II amp, they would reach a certain level and, as you say, they just couldn't seem to fill the room. To my ear, it seems as though they reach a certain volume level and then, beyond that, they just seem to compress.
I had, for years, been curious about the Aerial Acoustics 10T and, when a well used set came up on US Audio Mart for $1300, I pounced. I ended up having to replace a tweeter, but they are doing just what I want them to do and are my end-game speaker now. Of course, I'm 68 so I'm winding down on everything!  

I’m using Carver 305 tube mono blocks; about 400 watts into the 4 ohm 20.7’s.  I also have a pair of REL G-2 subs.  As minkwelder indicated, even with the addition of the REL’s the sound reaches a certain maximum that just doesn’t “fill” the room.  My room is approx 7,260 cubic feet!   

I used the 20.7’s for four years in a prior home in a dedicated room that was approx 4,095 cubic feet to much greater success.  

I need a speaker that sounds BIG in a big space and doesn’t cost $100k!

There is one particular box speaker that I’ve heard at the Shows for the last several years that has caught my attention; the Paradigm Persona.   I’ve only heard the smaller floor standing 3F’s but was favorably impressed.

I wonder if they are similar in sound to the Aerial’s?  How does the height, width, and depth of Aerial’s compare to the Maggie’s?  I like the large sound field of the Maggie’s, especially the height.  Performers sound ‘real sized’ not 3 feet tall as is the case of many smaller box speakers.

Moved from 20.1 to Joseph Audio Perspective2. 

Check out Tekton Moabs or Ulfberhts.  They will fill that large room with great sound that won't have you missing your Magnepans at all.
