I think I can say this - The Fenestrias don't boom as such at all BUT, they will overpower and overwhelm if used in too small a room and with less than correct matching gear I feel. In the large space I hear them in regularly, a Naim Statememt amp will give volumes to push you to the back wall (I don't know the wattage on paper here), while giving a sense of clarity and realism I've not really ever heard from Naim before (I think current streaming amps they make now are pretty good too - at a price - and the tractor look and feel of old Naims has long gone from such products, which is nice). Mind you, two hundred grand on the amp and speakers alone before sources is a hell of a lot of money, although people do spend this amount.

That system as pictured looks to me like one of the larger B&O installs we used to do. This speaker goes here and the other one over there, and I want the main source 'console' put here please..... That way, it'll be out of the way and still impress visitors.

See, The PMC QB1 is more my gear-lover's bag*, fully active and I suspect deafening with it, but you just can't fit monsters like these into a domestic environment, hence the Fenestria, which is passive to suit the intended market and vertically disposed to make it usable domestically. they've GOT to be better than the hideously priced Wilson confections I've seen for loads more money and heard (big box sound, but nothing spectacular by large pro monitor standards), which use good but not excessive drivers in lavish multi faceted cabinets which is where the cost goes...

Just my thoughts. Not for me really to question dealer recommendations now as I'm no longer a dealer, but the route I'd have suggested possibly wouldn't have meant shutting the door after the horse has bolted with dsp, room treatment add-ons and other crap...
