I recently picked up a pair of belles and wanted to get some advice on best placement in a not so desirable room. The room is 30' X 30'. The Belles sound pretty amazing, I haven't spectrum analyzed the room but there seems to be a hump around 120 - 140hz . I am driving the belles with a McIntosh MC150 along with a Paradigm Reference Servo 15 sub rolled off at about 45hz and 3 pair of Dukane Ionovacs electronically crossed over at 3500hz fed by a Mac240. The belles are fed a full range signal. I replaced the Belle crossovers with Bob Crites AA's. They are currently close to the corners. The "hump" is not noticible all the time but when its there, it is there. I had owned a pair of Ls Scala's 30 years ago but have been away from horn loads a long time Suggestions welcome Thanks!

New to the board here, and ready to be re-introduced to the heritage line after a 30 year absence. I owned a pair of La Scala's 30 years ago and recently acquired a pair of Belles. I haven't fired them up yet as the room addition will be ready in about a week. Reading thru the posts, I have a the AB crossover and have seen mention of crossover replacement. If anyone would like to summarize reasons for and direction to go would greatly be appreciated. I plan on driving them with either a McIntosh MC150 or a McIntosh MC7300. I also plan on either supplementing or replacing the tweeters with a couple pair of DuKane Ionovacs. Any info would greatly be appreciated Jack www.ionovac.com
