I set out to build the ultimate subwoofer and it is sort of a success. I finish my cabinet so it would look like the rest of my system. I add ½ Birchwood to my ¾ mdf for my exterior wall with the woofer side have 2 pieces of mdf sandwich together. Now my finishes on boxes have always left something to be desired. In the past, I have my buddies Gene and Eric Alexander finish my boxes after I build them but this finish looked great to me.
I took my Kove Armeggeddon (now called a Treo speaker) and put it in an 12.31 cubic ft box with extensive bracing which give me an port frequency of 22.69 Hz and an f3 21.64 Hz. Those are the lowest number that I've ever had with a speaker and box. I had my jbl subwoofer box (9 o 10 cu. ft) tuned lower than that (17hz) but it's f3 was 55hz. I've never encounter an f3 this low. So I was super excited about this project
Over the years my experience has taught me that facing the woofer down give you the most bass so that is how I faced my woofer and ports on this project.
I've finish today and went to audition it. It sucked. Only the low notes played and the subwoofer amp would keep shutting off. I threw my jbl 1500 gti speaker in the box and it sucked worse. I put the kove back in was going to settle for my disappointed sound when my wife pick up (her golden ears might just be better than mine. Over the years she has learned how to listen to music because of me and she's good. I value her opinion) on something. She was complaining about the rattle coming from the box. Now I know that my boxes don't rattle.
So I traced the sound to my woofer down by the ground by the box. there was tremendous pressure down there. It was so great that it was interfering with the woofer movement. The pressure was pushing against itself. It was stopping the performance. So I throw the box on its side and that fixes everything. I've never in my life heard bass this low.
I was feeling bass music on the back of my brain (that's the best that I can describe it). The only problem? The sub setup now looks ghetto. I'm going to have to fix this
