The "Ultra" 111s are in a 108sqm room (1,162sq/ft) room with 14ft ceilings. They are driven bi-amped with custom 450 IQs and Siegfried IIs
My Ultra 11s which should be here in less than 2 months will be in a 90 sq/m room and the twin they are coming with in ranch with an 85 sqn room both with 10.5m ceilings. I will be running mine with CH M1 monos, maybe 2 sets with the slave board in the future, the twin is on the waitlist for 450 IQs.
Yes they have room to breathe
Given midfield listening distances, Leif and I are pencil pushing on a baby Ultra for the asian/condo/flat market. I'm committed to picking up two pairs from the first batch built. These will be optimized for spaces between 20 and 30 square meters. The 55s can push out (mid to far field) to 50, the Ultra 9 to 75 without any strain. Less than 20 square, requiring near field listening, that would be stand mounts and subs. No plans for that under the Ultra line. The Unifield 1s and 2s are already very good and are actually the top sellers by volume. If there is demand from myself and my other fellow distributors we could demand an Ultra monitor. So far the demand has been for the baby/compact floorstanding Ultra so that is what we are pushing VSA to make. The no-holds barred monitor market is a very tight one with probably the widest competition vying for a very tough market to please with the smallest ROI comparatively.
