In Reply to: What the world needs is a good 10-12" LF driver for horns !! posted by Rafaro on January 31, 2016 at 12:41:55:
Hello Bill and groupIn my modeling of 10-12" driver sub woofer horns the limiting factor in producing high SPL DEEP bass has always been the Xmax more than the power tolerance of the driver. This negates the advantages of 10-12" drivers... the sturdy the cones, the good power tolerance with 3" or greater diameter VC. There has been, over the last 20 or so years, improvement in driver design. The use of 2 or more points of magnetic interaction with the VC by using 2-3 magnets gives a stronger push to the cone but Xmax has seen little improvement. Experimentation with driver suspensions has shown me that there is potential for several inches of Xmax but the difficulty has been in maintaining magnetic flux linearity along the contact point(s) of the V.C.
A compact but expandable subwoofer horn cabinet 1/2 wavelength at 35 Hz with a 10" driver has already been designed but the driver requires an Xmax of about 30mm for maximal performance. Manufacturers have not yet reached this potential that I am aware of but maybe somebody knows different??Regards to all
