      Product details

      Dayton Audio 18" Ultimax | DIY Kit | Component and Cabinet


      This particular cabinet is designed specifically for the Dayton Audio 18" Ultimax subwoofer, but works for any subwoofer with an overall diameter of 18-1/4" or less, and a cutout requirement of 16-3/4" or less. For optimum performance with the Ultimax 18" subwoofer, add four pounds of Acousta-Stuf polyfill for a Qtc of 0.707 and an f3 of 27 Hz. More info about the subwoofer can be found on the UM18-22 18" product page.


      During the CNC manufacturing process, rabbets and dadoes are cut into the back panel for precise panel alignment. A unique two-piece brace adds superior rigidity without affecting the subwoofer's performance. Both side panels feature 18 mm rabbeted extensions with recesses to perfectly install the first piece of the two-part, double thick baffle. Plate amplifier installation is made easy by following the scribed interior guide with a jig saw and by modifying one of the braces.


      The end result is a resonance-free, sealed subwoofer cabinet that is purpose-built to extract the best performance from Dayton Audio's 18" Ultimax subwoofer. All that's left to do is finish it to match your décor or paint it to stand out. When your friends ask about it, you get the pleasure of saying, "I built it myself!"

      Exchanged my svs sb 4000 for this and I was not disappointed in any way. It beats the sb4000 in every single way I can image. It even sounds better at higher bass at about 60-100hz although I cross it at 100 because at 120 it starts sounding worse than speakers

      Great kit! Cabinet cut preciselly, speaker is heavy-duty(no need to worry much about accidental damage). Pros: - cabinet pieces fit perfectly - speaker able to handle lot of power and generate lot of SPL. - sounds great with XLS1500 and Antimode - good packaging Cons: - very heavy (both cabinet and speaker) - need tools (6-8 clamps) to be able to glue correctly - need to handle surface to your liking - needs proper burn-in to loose the speaker
