New thread for the new build, The quest for insanity continues. I wont build this one for numbers either but will be active at Meca meets and just having fun. The goal here is to be very loud, low and sound good doing it. I'm hoping for 154's but want to do it peaking low, I would like 152's+ around 30hz, but main goal is to sound good, this will not be a burp box.

Updated Equipment List for this build

The wall will be completely double walled 3/4in 13 ply Russian Baltic Birch with 1/2in all thread bracing

19.5cu tuned to 31-33hz with 250-300sqin of port

Today I picked up SEVEN 5x5 sheets of Birch (420lbs worth) and will start making cuts maybe this weekend. I wanted to get the thread up so when I takes picks I can just add as I go. The best part is I can build this in my garage and slide box in when done, add the front beauty panel, seal the edges and done. I will be removing the bed of the truck to run all thread through the box and cab to secure it. Dont need a 600lbs projectile behind me. haha

Cannot wait for this to be done.

I want to see you "slide" in a 600lb wall lol.

Tuned in!

Here's the model you asked for. The green is a classic super boom box. It gives you more bottom end but you just don't have enough room for it. I played around with several box sizes and tunings staying within your deminsions and I'd stick with the plan you had the PM's so you can adjust tuning as you play with the system. The red is the 19 cubic feet tuned to 31.5 hertz that was talked about in the PM's.

Thanks alot, I know my truck peaks pretty low so I'm sure that will have some effect also. Did port area change that graph much?

Tuned in for this!

Might get loud

Swift's back at it again! HELLZ YEAH!

Ok looks like I am at 20cu ft. net tuned at 30.5, with 275in of port area. I think this will be fine. May not meter the loudest but should murder the lows, anybody find a good priced 5500 let me know.

I cant wait to see this. Sp4's murder the lows!....................Or so I have heard

So after looking at a Vent Mach calculator I am ending up with .040 - .052 depending on the power I run. From what I have read this looks like it will work good. I will post up some photos tonight of the enclosure being assembled hopefully.

Nice

What ?? No pics yet ??

love watching your builds.

Tuned in for picz

Hope you have this bangin by this weekend.

Hope you have this bangin by this weekend.

It's bangin, but only with 2. They still have not shipped yet so I guess they won't be here by Friday

Tuned in!

Dang....

I demand over night shipping!

Lol

Not that it matters.

Nothing exciting but pics of progress, Until I receive a "Shipped" status I will take my time, lol.

Love working with birch.

Baffle, doubled and rounded inside edges.

I have to go get the all thread I will use for bracing. I also will probably be using some 2in hardwood dowel for the vertical bracing so I do not have to run all thread through the port, although that may be a perfectly fine option. I also will probably use solid brass terminals instead of regular zinc plated. I will use 12 posts (one for each coil) so re-wiring can be done without removing subs.

i loved the first build, i really like what your doing with this one!

Well thought out and attention to the details, loving it.

Alittle progress here, I will try to add the bracing tonight and maybe get the port built.
