We all can get into trouble on New Year's Eve. We were at my brother's house and I had been having liberal brewskies. Not at all sober, I was marveling at the sound of his new Klipsch Quintet II system. He had replaced four big 1970s-era speakers with this set-up (supported by a good 12-inch powered sub) and it sounded amazing - the Quintets sounded big and loud and easily filled the large room with quality sound. On Jan. 2 I ran down to London Drugs and snatched the last five-speaker set of Quintet IIs they had for $199 CDN. The problem: In my room I can't get them to sound full, in spite of adjusting my Denon receiver's crossover from 80 to 100 then 120 hz. There seems to be a mid-bass gap between the sub and speakers. I miss my Mission M73 towers and Paradigm CC-70 center channel, which I sold off impusively to friends! The Klipsch speakers sound very crisp and nice and my wife is very happy with their appearance, but I think I may have made a big mistake in this impulsive buy. My brother's room is even bigger than mine, with a nine-foot open beam ceiling, so if anything, he should be experiencing more thin sound than I am, but it ain't the case. Any suggestions? Thanks in advance!
