Sunny,
The basic OHM CLS design has not changed much over the years. All including gen 1 from early 80's play as loud or louder than most anything else at comparable price I would say. I have used them outdoors for parties with listeners 50-100 yards away off 80 watt tandberg receiver and it went loud and clear with illusion of live music. I have never heard OHm walsh speakers be the bottleneck in terms of ability to go loud. Bigger models need more power and are capable of going louder with more bass extension, which is where the increased power demands comes in. Larger drivers are needed to go louder without compression and larger cabinets to go lower in most any speaker design. OHMs have this aspect nailed, few speakers do it better.
Tonal balance and detail has improved over teh years but the inherent design has not.
Omnis have a lot of advantages but most people are not used to them. Not all omnis are created equal. Walsh drivers have unique advantages. OHM has figured out how to do them well and keep it affordable. There is no better design for delivering the illusion of a live performance in ones home for reasonable cost IMHO. In my opinion, Lincoln Walsh got dynamic drivers right and most of the rest of the world works with a handicap accordingly. Of course, that is just my opinion. Most people are perfectly happy with traditional dynamic speaker designs. I like many myself, but always end up levitating back to the Walsh speakers.
