Posted September 3, 200520 yr I started to build a new enclosure today. Gross interior is 12.5 X 53.5 X 7.5 bottom and 3.5 top, so 2.5 cubic feet gross. I am recessing the amp and the panel is 22.5 X 13.5 X .75 sunk 1.5 into the enclosure. There are (4) 1 X 2 X 55 and (4) 1 X 2 X 12.5 to account for and the displacement of the sub (RL-P) I think is .18. I want to tune this thing as low as possible (28-32 Hz) so dual 3" ports probably. How long do I make them?
September 3, 200520 yr Author For reference, take a look at the box Ryan (tirefryr) built his g.f. I am sinking the amp on the slanted side is the only difference and size of course.http://www.soundsolutionsaudio.com/forum/i...topic=3615&st=0
September 3, 200520 yr Author I'm still working on the design. You changed the dimensions though <{POST_SNAPBACK}>Design hell, she's built . Just gotta cut out the ports and assemble in the truck
September 3, 200520 yr Author Just built it today, sorry for the miscommunications, only have a limited amount of time on my hands and wanted to make use of it.
September 3, 200520 yr well, here's the deal..lol...u've only got 2.13ft^3 gross using those dimensions...after figureing in ur amp recess at thes dimensions;22.5 X 13.5 X .75 sunk 1.5 into the enclosure, there goes another .26ft^3 take away the .18 for the sub...ur at 1.69ft^3i have no idea what those other numbers are for...but if those are the final dimensions...and assuming ur using shdl 40 pvc.....ur two 3" ports need to be 24.75" long for a tuning of 32hz in ur now 1.42net box.i think that covers everything.....and those are the for sure final dimensions?wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
September 3, 200520 yr That recessed area only displaces 0.132ft^3 Kent, since it will be mounted onto the 3/4" MDF to lower it 1.5" into the enclosure. For this enclosure:I already gave Kevin a length of 21.817, which will tune the enclosure to 30.5Hz @ 1.638ft^3.For other tuning frequencies:28Hz: 27.402" (1.593ft^3)29Hz: 24.982" (1.613ft^3)30Hz: 22.867" (1.63ft^3)31Hz: 20.997" (1.645ft^3)32Hz: 19.323" (1.659ft^3)
September 3, 200520 yr OK, Just thought of this... He has probably displaced another 0.75" of depth for the recessed area to build it So...I need a pic of how its installed Kevin
September 3, 200520 yr OK, Just thought of this... He has probably displaced another 0.75" of depth for the recessed area to build it So...I need a pic of how its installed Kevin so that the recessed area actually displaces like .26ft^3? because that's what i figured, the full 1.5" into the enclosure...he had way too many numbers in that post....lolwheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
September 3, 200520 yr sweet, the rl-p needed that lil bit of room..wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
September 4, 200520 yr Author Yep, found a new spot to mount the amps, pics will be coming soon, so I am utilizing the whole space (what little I have). Sorry, I know there were a lot of numbers in there, but hey, ya gotta make an attemp . But big,big thanks Scott, got the ports cut and in, the box is drying tonight and is going in with the new amp rack tomorrow. And thanks to you to Kent, but I am glad I figured out a way not to sink the amp in the box and eat up too much space .
