Oh yeah! You heard me right! Sub-Woof-Er-Sat-Ur-Day!!!
I have two projects lined up for you guys.
First off! A UM18-22 in a Full Marty Cabinet... but BIGGER! This subwoofer is for my bedroom's 2.1 system which will are Ascend Acoustics CMT340's soon to be paired with my "Fuller Marty" if you may.
Second! Two Dayton SD215-88's in a 2.5 cuf cabinet tuned to 35 hz! This subwoofer is for my Dad's 2018 Civic Si. Goal was clean, undistorted sound in a smallish form factor. And needed to be cheap. This marked every box.
So to start off, I'll talk a bit more about the Dual 8" subwoofer. Recently I decided to take these two bookshelf speakers with 10" woofers and wire them to the subwoofer in the back of the civic. Worked great, so much more output than the stock 7" thing that you can barely call a subwoofer. Unfortunately those bookshelves are extremely big and my dad was quite mad they took up so much of his trunk. So I proposed an actual subwoofer that had a smaller form factor but just as much, if not more output. It also needed to be cheap. So I took to Parts Express and started looking. Found Dayton Audio's SD215-88 Drivers which were priced at $30 a piece, didn't want a huge box, and had good output. Bang, done. So here I am cutting wood for the Fuller Marty and I think to myself "Wait there is enough scraps here to build another subwoofer box" and that box is this box which will house the two 8" subwoofers.
Alright now to the Fuller Marty. So I currently listen to music in my room in two channel with my Ascend CMT340's. Really fantastic, these speakers sound great in two channel with no subwoofer. But I know what a subwoofer could do for this system so I took to the forums looking for good builds for ULF and high output while staying relatively simple and cheap (You won't find me building a horn loaded subwoofer anytime soon!) and found the Full Marty. I thought hey, this design is good but I think I can do a little better. Since this subwoofer would be going inside my closet, I have a max Height of 64". The Full Marty only went to 48" and by now I'm sure you guys know what I was thinking
So yes I made the box 16" taller and lowered the port tune to about 15hz. So its a "Fuller" Marty
So here is the cut list for the Fuller Marty:
I do not have a cut list for the other subwoofer because I actually drafted and designed it on the spot (Yes, I'm just thaaaaat amazing
Alright here is the wood which we finished cutting. The bottom most is the Full Marty. Then there are some cuts of birch plywood for my Blast Box project. I had three sheets of MDF total to use, and we still have a bit of extra for any extra bracing I may feel the need to add in.
We resume tomorrow to assemble it all. Including the Blast Box: Extreme Edition.
