Hi all In my living room I currently have Artcoustic speakers; they are placed high on the wall compared to traditional speakers, and for obvious reasons aren't toe'd in, I also have a somewhat sizeable centre speaker which is sunk into a recess beneath the TV. Ever since I heard some JBL 3677s I've realised that most domestic speakers don't deliver what I want. I've owned/used lots of kit over the years - lots of M&K, more Genelecs than you could justify, PMCs, XTZs, passives, actives etc...but none of them deliver effortless dynamics at loud volumes, and that distinct, direct punchiness - in short, the kind of presentation you experience at a very good cinema, and the type of presentation you get from a compression driver. My question is, is it possible to DIY a flat(ish) panel speaker to give me what I want? We've just refurbished our living room (again), not quite finished but you get the idea of what I have to work with. The L&R speaker sizes could change, but they have to be in those positions; I want to mount speaker grills like the ones I have below (those ones are photos of my kids, just printed on speaker grill cloth). This is them with the grills off: My speakers right now are Artcoustic DF 75-55x2s, and the centre is the Arcoustic DFC 150-36 X2. I guess the biggest limiting factor will be depth (the artcoustics are just over 5" deep, and I think much deeper will be pushing it). Any thoughts?
