Gorilla83's subs received the nickname "The Silverbacks", so i figured i would pay homage to that and call my project "The Grizzlies" since they will have a old school rustic look to them. Maybe nicknames are earned not given. i dont know. 
I have decided to build these after reading through Gorilla83's thread for his dual opposed Dayton HO18 subs. i was going to build those, but i jumped on the sale Amazon is having on the EP4000 amps and bought two of them instead of the more expensive, yet better matched CV5000. I wouldnt be able to get the power i wanted to the Daytons with these amps due to the limited wiring options. The SI HT18's have a dual 4ohm VC which allows me to wire two drivers in each cab into a 4 ohm load. That will put about 1000 watts into each driver which should do the trick. the pre-order price also saves me some cash. so im hoping i can get the same performance as the Daytons on a CV5000 amp for less
I am using 13 ply 3/4" Baltic Birch for the cabinet. My box design is the same as Gorilla83's except i am going to recess the entire baffle 1.25". This will require me to increase the total depth by 2.5" making the dimensions 25H x 23W x 31.25D. To do this, im going to be adding blocking inside to support the baffle. the blocking will be 3/4" x 3/4" and 15' total. this decreases the interior volume by 101.24 cubic inches. i wonder if thats ok, or if i should increase some other dimensions to make up for it?
I have ordered four D4 drivers from Stereo Integrity. they are supposed to start shipping by end of the month. im still shopping around for the BB plywood as i feel like im paying too much where i have been getting it(Manns Lumber).
I should start building the cabinets in the next couple weeks. i wanted to start this thread to hopefully start getting some input and im sure there are a lot of folks planning builds with these so i hope it helps them as well.
