I can't speak for Oliver however the large multiple Aeon subwoofers are really not affordable for most and and are extremely large. I personally prefer two subs in a system and with the Sovereigns that is somewhat practical

and with the Aeon subs it is truly only for a limited few. The Sovereigns are IMO incredible and I have not heard the arrays in a very long time but at thier price points I decided not to bring them into the US as I don't see them as something I can really sell. The Majestic is much the same these few products are for a very small select group and that group can listen in Germany and decide if this is what they want. I look at those items as a true custom order event.
Back to the sovereigns , this client has had many subs and sub arrays ( no names mentioned) he returned or sold the others as they made his system worse. I posted his comments in the post following the picture and I just spoke to him earlier today. He and I feel the same way as to what they did in my room and in his.
Oliver did an amazing job and the subs are something that should be heard in a great system.
See you at Axpona and we will have the subs there and I will try my best to get a great result in the room.
