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

Wow, got a lot of flak on this one. It is not the end of the world; I will just sell them if I dislike them or made a mistake.

To Mapman: will follow your prescription and see what happens. I am not sure about the usefulness of aiming the tweeters 2-3 ft to the side, but I will that a shot.

To Rrog, I owned a pair of GM Europas about 8 years ago. Very nice speaker, but was a bit bass shy; They also are expensive used and heavy to ship.( there is a pair on AG now or was) As far as Von Schweikert VR-1, there was a pair on AG about a month ago, but could not come to agreement on price with buyer.I am still not convinced that this is the best bookshelf value out there. BTW, I bought the Marimbas from an internet dealer who may have not have an official return policy, and he does not have another speaker in his inventory that interested me in my price range

MoFI, the Marimbas have about 7 hours on them, so I am far from Nirvana. 400-500 hours seems alot as recommended by Marak

I do appreciate everybody's commments and advice, but there are many speakers out there to consider as an alternative to my main speakers. Totem's Dreamcatcher; Rainmaker, and even the short floorstanders like the Arro and Stff models are viable choices.

The Epos 5i and 12i though discontinued seemed to be favored by Bob Reina of Stereophile. I believe I auditioned the original M-12 about 7 years ago, and was impressed by "how right they sounded" I don't have the opportunity of auditioning that many speakers in Honolulu because the 2 only high end dealers display 2K and above speakers because every turn must count to stay in business.

As MOFI noted there are many choices out there; manybe I should have spent a bit more money and bought the freakin VR-1. Nevertheless, I am having fun.
TO ZB542, The amps are a pair Red Dragon digital monoblocks, and a Bel Canto PRe3 line stage. Speaker cable: Audio Art SC-5 (not special edition, that is the SE version)
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.
