Help with a Small Mistake

[rhart]

Hi All,

A friend of mine built me some BS cabinents for a Fostex FE206E (I know the 207E is better and I'll upgrade when I can find some for a good price). The dimensions are 20h x 9.5w x 13d. I just realized that the holes he cut for the drivers on each cab are not the same height. There is a 1cm difference.

Is this going to be a problem? I know I could just cut out the difference, but I'd rather not if this is not likely to effect the sound. I'd appreciate any help and comments.

thanks

Hi,

no, get some grilles and don't worry about it.

Acoustically it should be insignificant, but if you're like me,
asymmetry will drive you crazy.

I had once a couple of little cabinets for FRS8s. I gave to a friend to cut the holes. One had 1cm difference in hight.
I conducted listening tests. The cabinets were closed box bipole so I could flip em for direct comparison since only one hole was wrong in hight. Well I could not believe the loss of focus when I listened to the missaligned faces vs right ones. It was much more notable than differences in horizontal movement of the cabinets in relation to eachother up to 3cm. My suggestion is to use bases with different thickness so to equalize the difference.

Thanks everyone. I'm re-assured. With the speakers set-up, I think I can either choose not to notice the 1cm difference (or tilt my head a bit). Or, I suppose I could simply adjust the stands. So long as they sound identical, that's most important. I'll post some pics soon. They're veneered with real rosewood and look really nice...now let's hope they sound as good.

PS Has anyone tried the Cascade Quiet Kote that parts express sells for dampling cabinents?

Nelson,

I can certainly sympathize with that. If a painiting on the wall behind the TV is but a fraction out of level, I can't watch TV until I straighten it.

I like sreten's suggestion of grilles as "black cars look better in the shade" (never mind the actual alludings)

Another solution, if you have the right listening room, would be to place the speaker with the lowest driver on the South side of the room and the one with the higher driver on the North side thus utilizing the earth's curvature to restore the balance. If this doesn't quite fix the problem then placing shims under the your chair's right legs should allow you to dial it in. This all assumes that your listening position is facing West. If you live in the Eastern Hemisphere, then of course you'll need to completely reverse all of the above. A more detailed explanation can be found in my upcoming book: "The Art of Speaker Feng Gooie".

OTOH, it may not be a problem (sonically) in the first place:^)

If it really bugs you aesthetically (it would me), you could always make mounting rings 1cm larger than the drivers, and elongate the original holes.

I repeat, its been experienced and it creates a problem with image focus. It MUST be adressed.
