I currently have an SB12-nsd and I feel that it is lacking the wow factor a bit, so I am thinking about building my own. I have a false wall about 3 feet from the real wall, and could go as high as four feet and as wide as four feet. I don't know how close it can be to the AT screen, but I'm thinking my max would be 2'x4'x4'. That's all I know.
I was thinking that a ported box with an 18' driver would give me a more "immersive" sensation. So what do I do now? I need a driver and and amp... and I need to make a box (duh!). Can I just connect my amp to the pre-out and then run that to my sub as I do with the sb12? My room is 6'9" x 11' x 23' feet, semi dedicated. What do you guys suggest? I don't need blow away power, just a couple notches of improvement from the SB12; more fullness. I would like to keep the cost under $700... any suggestions? Is it possible to blow away the SB12 with this budget?
Thanks in advance... and for helping a noob.
Also, I am in Canada, which puts a dent in the budget right off the bat.
If you don't mind driving to the South shore of Montreal (10 minutes from Champlain bridge)...I invite you to come and see and hear my DIY setup.
I'd be more than happy to show you and answer any questions you may have.
This is your best resource for anything related to building simple ported boxes. Have a read through that thread and if you've still got questions I, along with many others will be happy to help.
I read some of the marty builds, but this is the panacea! Just a few questions... does it matter where I put the driver relative to the port? Also, let's say I were to make two... what would be the best configuration for smooth bass response, keeping in mind that they would both have to be behind the false wall. Standing tall, side by side, stacked length wise, etc..
As far as how the driver is orientated in the box I don't "think" it matters. And how to configure the two enclosures is actually up for debate, I've had different experiences pointing the subs in different directions in my room. And smoothest response that's kinda trial and error in my books. Try posting up some pics of your room and the space you have to work with. It'll give a better idea to the guys here.
The inuke 3K will be sufficient for 2 marty style subs. If you have even the slightest inclination you will end up with more than 2 and the extra $100 or so won't break the bank, get the 6K.
I have 2 and a 3K and my house shakes. Due to WAF I won't be adding any more subs until we move at least
Depends which style you plan to build and what you plan tune the port to. My mini marty I used 3" port rails, and my cube has 2".
Have you been able to check out the martysub thread? LOTS of great information there.
This is the martycube but the port idea is the same just different sizes. Hope it helps explain a little as to how its built. I too had a hard timing picturing it.
I don't think so, I would check the full marty dimensions for the port and see if it goes all the way across and then back up or if its shorter than the length of the side it is on. If it is then it doesnt go all the back and up.
According to the picture referenced above it does look like they run up the back. I think there might be a typo on the amount of rails needed for the back, it should say (2) not (1). that would mean that the bottom rails 3"x20.25" would almost reach the back but it will be short about 3.25" which would account for the 3" wide rails going up "Back Rails", something like that I cannot see both the picture and write this at the same time on my phone but I think you get the idea.
For what its worth, I built a stonehenge box and used an SI 18" D2 wired in series running it with a nu3000dsp with the limit at 2600 watts and its awesome, the box can be found here http://www.diysoundgroup.com/ported-subwoofers-1/18-stonehenge.html you would need the panels and sub structure.
Its a beautiful design that assembles super easy, I have never done it before and I had mine done in about 1 1/2 hours with glue set time.
You would only need a few extra parts besides the amp, box and driver and your on your way! BTW definitely get the DSP model amp so you can use a UMM-6 or similar mic and EQ the sub using REW, its actually not very hard once you start playing with it!
Im pretty sure he ships to canada but you woukd have to email him for a quote. He responded almost instantly to my emails. Worth a shot.
