'Compression of dynamic range'? What does that mean?I would say yes, if you dont mind a compression of dynamic range, restriction in GrahamN type volume levels and lack of real bass extension and impact.
Obviously levels are limited, but not in a meaningful way in a normal sized room. IME. There is a health issue here.
I accept that some sub-woofer fans like big rumbling noises, but in real terms the ESL63s shake the coffee table and wobble the sofa. Getting good bass extension is going to be down to installation, but I think the speakers go down well below 50Hz in a way that a stand mounted conventional job simply cannot emulate.
I hope the speakers work well at Julian's, perhaps we can cause confusion... I think he has quite a narrow room, so if we can get them away from the rear and close to the sides we should be OK. Piling the contents of his airing cupboard behind may also help.
