Instead of trying to get a particular kind of sound out of a speaker that doesn't have that sound, you would have a better chance at success if you selected a speaker that you can be sure will deliver the kind of sound you want.

Check out Weber VST speakers. The user comments {Select Page -> User Comments} are very helpful. And there are explanations of how the different magnet structures and cone shapes affect the sound. You can also e-mail Ted Weber about any of his products, and he will usually answer within a day or two. How many companies have customer questions answered by the President himself?

I read through the tech data and the user comments to narrow down my choices to a couple of models. Then I e-mailed Mr. Weber to get some guidance on which of those would be best for my application. The man speaks true. I got exactly what I wanted from my Weber speaker.
