Marchant89 Posted November 14, 2021 Report Share Posted November 14, 2021 I have tried and tried multiple enclosures and 2/3 15s I never can quite seem to get past 147db on a musical build. Just built a new enclosure for 3 Fi ssds at 11.25 cubic feet and still can hit much past 145 on music. Running a crescendo bc6k on 3 Fi ssds.

pnutz37 Posted November 15, 2021 Report Share Posted November 15, 2021 I have a bunch of questions: Is the 11.25 cubic ft Net or Gross? What's your port area? What frequency did you get your 147? What do you have the enclosure tuned to? 1 Quote Link to comment Share on other sites More sharing options...
Marchant89 Posted November 15, 2021 Author Report Share Posted November 15, 2021 (edited) @pnutz37Port is currently 114”, if I did the math right 25 x 4 3/4. I would imagine the 11.25 is without displacement. 147 is at 39hz on a sine sweep box is tuned at 32hz Edited November 15, 2021 by Marchant89 Quote Link to comment Share on other sites More sharing options...
Marchant89 Posted November 15, 2021 Author Report Share Posted November 15, 2021 I tried port up as well no worthy changes on meter Quote Link to comment Share on other sites More sharing options...
Marchant89 Posted November 15, 2021 Author Report Share Posted November 15, 2021 This also maybe a really stupid question can you mix slot with aero if more port area is needed and can’t be adjusted on box? Quote Link to comment Share on other sites More sharing options...

Marchant89 Posted November 15, 2021 Author Report Share Posted November 15, 2021 @Never Enough Basswell I thought those were related. I’m not competing just trying to get loud Quote Link to comment Share on other sites More sharing options...
killerc998 Posted November 15, 2021 Report Share Posted November 15, 2021 (edited) 11.25 with out displacement could become 7 with port, bracing, and subs accounted for. My box is a hair under 10 before and 7.5 after tuned to 36. The lower the hrz the longer the port, and the more space gets eaten.
