Diffraction of sound arond a oillar3/24/2024 ![]() Personally I think the tweeter must be in front, if you cant see your tweeter with your eyes you aren’t hearing it all with your ears. In this configuration I’ve created an invisible cone which can have correct alignment everywhere inside it. In a standard side by side baffle configuration your perfect alignment will only ever be in one plane, hopefully it intersects with the driver seat. With this configuration i have, on average, more area in the car to sit where the alignment is good. Phase becomes your best friend in this configuration. Positioning of the tweeter was done with an initial tweeter baffle print and my ears. My main goal was to maximize the front air space and minimize the height of the tweeter, for space reasons. ![]() The bullet shape you refer to may help with some turbulence but id have to pull the tweeter even farther away from the 3in to result in the same air space i have in front of it. With a 3 inch woofer beaming can start to occur around 2k but most people wouldnt notice the effect on an A B comparison till around 3k or higher. As long as you are willing to accept a slightly lower than spec’d xover point for the 3in and tweeter you see here, then there’s really no tradeoffs. How does that tweeter sound on and of axis? Do you think the inverted dome is better then the typical dome tweeter, and how does it compare with other tweeters that you have experience with?Ĭlick to expand.Hey Mickey thanks for the comments. Now take better photos! LOL! They look like they took some time to make. Have you thought about doing it Backwards? Say for example using a tear drop shape behind the mid range, and then having the tweeter behind it in a wave guide? That would seem to work better on paper I think as the physics play out that way with some drivers. For the axisymmetric scattering from a circular disc, a highly effective symmetric formulation results, and results agree with reference solutions across the entire frequency range.I'm sorry if I missed the other post, but I would like ask if you are willing to share your thoughts about if this mounting method has any sonic tradeoffs with a standard baffle configuration.ĭid you see any sonic benefits doing something more of a Bullet shape for the back of the tweeter cup or a classic tear drop shape?ĭoes it sound different having the tweeter in front? How have you compensated for things like Phase cancellations and anomalies. No problems with irregular frequencies, as happen with the Kirchhoff–Helmholtz integral equation, are observed for this formulation. Numerical experiments demonstrate accurate response for frequencies down to 0 for thin plates and a cube. In a subsequent step, this edge source signal is propagated to yield a multiple-order diffracted field, taking all diffraction orders into account. This gives what can be called an edge source signal. It is shown that the multiple-order diffraction component can be found via the solution to an integral equation formulated on pairs of edge points. An existing secondary-source model for edge diffraction from finite edges is extended to handle multiple diffraction of all orders. The formulation is based on decomposing the field into geometrical acoustics, first-order, and multiple-order edge diffraction components. A formulation of the problem of scattering from obstacles with edges is presented.
