Any expert opinions on these vertical Marty subs? Are they going to give the same performance?
fperra, have you made any measurements on these?

vertical or horizontal will have some different effects in how they work with the walls/floor etc. and it can't really be said that one will be better than the other. so as far as a rule of thumb, the performance will be the same whether upright or horizontal or even sideways as in the Cyclops design.

Listen. It's All Good.

Well I got the enclosure together finally. Sub is mounted in it and ive been playing with it since late Sunday evening. Playing test tones it went as low as 14 hz, after that it just sort of dropped off. Much better than my dayton sub 1200 which was dropping off at 28 hz. I ended up using an ultimax 18 in this box instead of an ultimax 15. This sub is supposed to be going into my living room but im having a hard time going back to the sub 1200 in the office after having heard this one. Ill probably end up building a mini marty or maybe a cube now.

I've never built a speaker or sub before and I was wondering if anyone could help me out. I have 3 JBL 4722's and want to put them behind a AT screen. Could I modify a full or mini marty to match the 17.5" depth of my JBL's? Space is limited. Thanks!

@squiers007 I think makes some, you could find him in this thread, or even post your same question over here.. MartySub FAQ

If I do that, what would be the optimal slot port for either a 16hz tune, or a 17hz tune? I like the idea of using a side ways slot port, I just need to figure out the optimal hight width, and depth of the slot port, and the hight, width, and depth of the front baffle?

The rear panel would just use a complete 2' by 2' sheet, right?
Make sure to measure those..........The one's I bought were NOT exactly 24" x 48".
Just a head's up.

I'm re-doing a box that is 2' x 2' x 44" long. .....3/4" Baltic Burch

Rather than constructing a slot port (which is fine ) ..we're gonna try the two corner / triangle ports.

The internal dimensions of the box are 22.5" x 22.5" x 42.5"

So each triangular port will be (measured internally ) 7" tall x 7" wide x 40" long ....hope we have that right. This is for the Dayton RSS460HO-4


Here's the box originally




Now we're putting on a new front baffle

The old one is already off

I currently have two Marty subs with the 18" Dayton 460HO's. I am framing the baffle wall in my new dedicated by room this weekend, and only have 2.5' behind the baffle wall. So being as I want to have my two Marty subs in the baffle wall, (I will soon build two more that I can put in the rear) I am going to have to build some new Marty Sub enclosures that are vertical with the subs and port mounted in the front.

With that in mind, I can't decide if I want to do slot ports again or round ports. Here is a question for LTD02..If I go slot ports in the front, how long should they be, and how should the snake up the back of the enclosure? Or if I use round ports, what size should they be?

I know I'm not LTD02, but I thought I'd chime in.

Which Marty Sub? The box size, port area, and tuning will determine port length.

I've got MartySub and Custom subwoofer flatpacks for Sale. !! Flatpack sales are on hold through March 15th, however we are still taking orders to be completed starting in March!! PM me with questions about custom designed flatpacks. MartySub Flatpacks are back

Are you putting any bracing and absorption liner inside ?

@Tip24/96
if you keep the internal volume of the sub the same, then the size of the slot would remain the same.
for an angled slot, just measure down the middle of the port. if it is off by an inch one way or another, it won't matter.
if you get stuck, shoot me a pm. it was just by chance that i saw your question here.

Listen. It's All Good.

Just about six 1 3/8" dowel pieces of wood.

Nothing at all for lining the box.

Had thought to just throw in 5lbs of polyfill ..acquired from Parts Express

But i have read that in a ported box ..this acustastuff polyfill isn't so important
But that lining the box is.

How many walls should be lined ?

I do have some that egg crate looking stuff up in the rafters of the garage


LTD02 is in the house !

LTD02 ..did you get the original idea for this MartySub in anyway from the 2001 Adire Audio Tempest EBS design plans ?

I think the back wall and sides should be lined. I don't know if the backside of the baffle needs it.
As per your other thread question, I am getting similar lengths as LTD02 for your triangle ports.
2 ports approx. 40" long to get into the 18hz tuning.
I don't think you have enough room for that length and still leave enough space for the inside end of the port opening.

the marty sub came out of a request from a forum member, martycool007, who was looking for something that would be relatively simple to build and would maximize performance of the 460ho driver. in its original conception the large panels were 24"x48" +/- (i.e. pre-cut handi-panels available from h.d.) and the smaller panels required only one cut. starting with the handi-panels (assuming the ones purchased are all the exact same width), only crosscuts (and driver cutout) are required to complete the entire cab. so in this case, it was more about the availability of materials and construction method than the size and tuning of the cab. the so-called mini-marty achieves almost all of the performance, is a little smaller, but requires a little more chopping.
DIY Subwoofer help needed after reading.
the relative simplicity and cut-sheet friendly 2' wide panels survive though. :-)

I've built many sealed subs before. Im ready to get into the ported game now. i have 2 Dayton ultimax 18s and a Inuke 6000DSP on the way. Am I correct in thinking that the marty's would be good for the subs I bought? I was running a WMD18 in a sealed 4cu ft box with an EP4000. I need more low bass. This setup might be a little over kill being that it will be in a 1400 cu ft room.

those drivers do a little better in the big cabs, so if the full size is possible go for that. if not, the revised minimarty is another option.

there are also other form factors that will perform more or less the same. the Cyclops build comes to mind. also, the big cabs that notnyt designed. lots of options. probably best to figure out what form factor you would like then hunt around for a design. there are countless designs floating around that will work just fine with the um18's.

I have no problems using the big ones. I like the 2' x 2' x 4' size. I can use 1 up front and 1 behind my seats. These should pressurize my small room nicely.

Thanks for the quick reply LTD02. What exactly was the port length? ive seen a few different numbers. I should be able to have these done this weekend. Subs wont be here till Tuesday so I can take my time building them. Just need to decide on a finish for them.
