Getting overtone in a pair of bookshelf speaker.


I just bought a pair of Music Hall Marimba bookshelf speakers, and currently experimenting with placement. I changed the previous height of the tweeter by placing two books under each cabinet. During the first listening session, they sounded OK, but now today after the changes made, they sounded crinkly in the high end with somewhat of hollow overtone in the midrange.

I do not expect them to pressurize a 12X14 room with full sound, but I am a bit disappointed at the tonal balance. I have them about 4 ft from the side walls and 15 inches from back wall which is glass, but has slat shades that can be closed. They are approx 5 ft apart and occupy the far end of the long axis. Need suggestions on how to find ideal tonal balance. Thanks

Jim, You mentioned the speakers sounded ok until you raised them up. Maybe you should lower the speakers to their original height and just listen for a while as your new speakers break in.
TO Rrog, Actually, I followed Mapman's plan, and it improved the sound alot. The stands I have are semi-crap and are 24 inches high. I elevated the speaker to bring close to ear level. But, I will try your suggestion. There is lots of Koa wood in the islands which is very dense. If I could find a local woodworker to build me a pair of stands, that would be great

To Quad-man, these are $350 speakers. Despite Roy Hall's brittle personality, the guy is no asshole. The Marimbas are above average speakers and may get better. Though I have a feeling that Mike Creek had something to do with designing them. These are not my main speakers, and am just pushing the envelope of the budget class speaker. Why?? It offers an alternative diversion to leering at 20 year old college women on the beach

If you have any questions for so-called better bookshelf speakers, bring it on; I am open to suggestions
Take a look at Stereophile's round up of bookshelf speakers reviews, they seem endless.
