Linkwitz transform equalizers: |
| The following equalizers implement a Linkwitz transform function, a specialized form of bass boost which permits you to effectively change the Fb and Qtc of a sealed speaker system. Note that the Linkwitz transform provides bass boost below the natural F3 of the system, so your subwoofer excursion should be up to the job. |
