- 2. The speaker enclosure according to claim 1, wherein the baffle has a horizontal transition surface adjacent to the mid frequency wave guide that is narrower than a transition surface adjacent to the high frequency wave guide.
- 3. The speaker enclosure according to claim 1, wherein the outer edge of the baffle forms a parabola.
- 4. A speaker enclosure, comprising:a back housing having an opening; and a baffle tapered inward in a horizontal axis and a vertical axis and adapted to enclose the opening, the baffle having a high frequency wave guide associating with a high frequency driver and a mid frequency wave guide associating with a mid frequency driver.
- 5. The speaker enclosure according to claim 4, wherein the baffle has a portion along the longitudinal axis adjacent to the high frequency wave guide and having a length between a focal point of the high frequency wave guide and an edge of the baffle that is greater than a longest wavelength from the high frequency driver acting to stabilize wave fronts from the high frequency driver in the vertical axis.
- 6. The speaker housing according to claim 4, wherein the length is at least about 3.5 inches.
- 7. The speaker enclosure according to claim 4, wherein the high and mid frequency drivers have a cross over between about 2.0 KHz and 3.0 KHz.
- 8. The speaker enclosure according to claim 4, wherein the mid frequency driver operates in the frequency range between about 100 HZ and 2.5 KHz.
- 9. The speaker enclosure according to claim 4, wherein the high frequency driver operates above about 2.0 KHz.
- 10. The speaker enclosure according to claim 4, wherein the baffle has a portion that is adjacent to the high frequency wave guide, wherein the portion forms a parabola along an edge of the baffle in a longitudinal axis.
- 11. The speaker enclosure according to claim 4, wherein the baffle has a horizontal transition surface adjacent to the mid frequency wave guide that is narrower than a transition surface adjacent to the high frequency wave guide.
- 12. The speaker enclosure according to claim 4, wherein the back housing has a bottom side that taper inward.
- 13. The speaker enclosure according to claim 4, wherein the back housing includes a topside, a bottom side, and left and right sides all tapering inward towards a back side.
- 14. A method for manufacturing a speaker enclosure, comprising:adapting a baffle to associate with a mid frequency and high frequency drivers; inwardly tapering the baffle; and elongating a portion of the baffle that is adjacent to a high frequency wave guide along a vertical axis.
- 15. A method according to claim 14, further including:rounding an edge of the baffle adjacent to the high frequency wave guide in a longitudinal axis.
- 16. A method according to claim 15, wherein the edge forms a parabola shape.
- 17. A method according to claim 14, further including:enclosing the baffle to house the mid and high frequency drivers, where the enclosure has a plurality of inwardly tapering walls to encompassing the mid and high frequency drivers.
- 18. A method according to claim 14, wherein the elongating the portion of the baffle is substantially an extension of the high frequency wave guide to direct and stabilize wave fronts from the high frequency driver.
- 19. A method according to claim 18, wherein the elongating the portion of the baffle is at least as long as a longest wavelength propagating from the high frequency driver.
- 20. A speaker enclosure for housing a high frequency driver and a mid frequency driver, comprising:a back housing having an opening; and a baffle enclosing the opening of the back housing, the baffle having a high frequency wave guide for the high frequency driver and a mid frequency guide for the mid frequency driver, where the baffle adjacent to the high frequency wave guide tapers inward.
- 21. The speaker enclosure according to claim 20, where the baffle is elongated along an longitudinal axis to increase to the transition surface area adjacent to the high frequency wave guide.
- 22. The speaker enclosure according to claim 20, where the baffle forms a smooth transition from the high frequency wave guide to the edge of the baffle.
- 23. The speaker enclosure according to claim 20, where the back housing has a back side that has a smaller surface area than the baffle.
- 24. The speaker enclosure according to claim 20, where the back housing has a back side, and the back housing tapers inward towards the back side.
- 25. A method for housing a high frequency driver and a mid range driver to minimize eddy currents from occurring, comprising:transitioning a baffle smoothly from a high frequency wave guide to the edge of a back housing; transitioning the baffle smoothly from a medium frequency wave guide to the edge of the back housing; and increasing the transitioning area from the high frequency wave guide to the edge of the back housing along an elongated axis.
- 26. The method according to claim 25, further including:tapering the back housing towards the back side of the back housing.
