David,
The only corners i could use are covered from floor to ceiling by bass traps(minichunks) made of rockwool and covered by 5 thin panels of wood of 2'x2' for each corner not to deaden the room.I would have to remove 3 of them in each corner to allow enough space for the two 604 and enough air around the drivers.I will then have in each corner one covered bass trap of 2'x2' at floor level and another one at ceiling level ,leaving enough space in between for a baffle about 3.5' wide 6.0' high ;I dont know wether this is enough to do the trick. If i get rid of the 2 bass trap together,i dont know what kind of impact it will have on the acoustic of the room which i spent months to treat acoustically with decent results for a relatively small room. By the way,when you refer to" Eq or series resistance to balance the system" ,how do you achieve that?
Any way we have got a potential option that i could work on with some additional guidance.
Regarding closed boxes not to have to worry about measures of the speakers,how big is "large enough"?I have to tell you that the 11.3 cb feet of my friend 's speakers are the maximum size i can accomodate .Actually i would prefer taller but not as wide boxes.
Thanks again for your input David.
Charly.
