Don't think so, it would have to be pretty tall or it would be dual martycube.

As long as you double everything up it should work out just fine.
You would have to get creative with the dimensions it would end up being pretty large.
I could see making the cabinet 72 inches or more in height to get the volume needed for a large ported enclosure like a Marty.
Most of us would probably opt to build 2 cabinets to have better placement option and to better smooth out in room response.

That said would sure love to see a dual vertical Marty built.

I was going to build a dual driver front firing sub like this:


But ended up finding it would be easier to build two separate subs.

I was thinking to take up less space. But I guess I could stack them on top of each other. as well. I am in the think out loud stage.

Trying to take less floor space up. I was going to do 2 on left(dual) and 2 on right(dual) 4 drivers 2 boxes.

If i did 4 separate I am thinking I can stack if needed or make better placement. Hmmmm.

People generally just build them separately, as they are quite heavy as a single alone, and a dual marty sub would be 2x2x8 and a few hundred pounds. Basically impossible to move and wouldn't fit in most places.

Take a look at my build thread and you can see what I did, I don't consider my subs a "Marty" sub though...lol


they also have a side firing port because they are behind my AT screen.

there was something designed a while back. i baptized them as the annihilators, but others like project annihilation more.


might be something worth considering given what you are trying to do. and, personally, i think it looks kind of badazz. :-)

If you had the room for cabinets like mine you could do an entire build like mine for under $2500. If you used the new UM18-22 drivers your looking at $1150 for four drivers, you could power all four off of a single Peavey IPR2 7500 amp so that would set you back $800, or you could use two iNuke 6000DSP's to power them and that would set you back $800 too. About $500 for wood (probably less) and some odds and ends like cables and connectors.

I'm just in the process of going to the Peavey 7500 too, that will power all four of my subs.

I did a dual 15" vertical "marty style" with port on top facing front. Woofers facing front too. 24" wide. 24" deep. 42" tall (although 48" tall might make sense)

It's not a marty anymore. It's just a ported dual sub box. But year you can do that. It's rather easy. 2 drivers has nicer response than 1 anyways, digs deeper and overall smoother. More output. Can't loose with that.

I want to see some pictures!...lol
I actually considered building some new subs with 8 ported 15's but after talking with LTD02 its pretty much a lateral move. Wouldn't really offer anything more then I already have.

I had post in JPA theater build showing it in the background:

The Plains Theater

Far left. Ignore the margarita machines, beer boxes etc...

Yes my garage is messy. Yes I have a wall of sound and subs in my garage

I hate to try to highjack a thread as a LONG time lurker and first time poster, but I can lurk no more. I've been doing some serious lurking lately and am planning to build a pair of subs. Basically 2 vertical marty's with single drivers All the usual suspects seem to be on this thread and I was hoping to solicit a few opinions before I start chopping up my lumber tonight. In hand I have 2 ultimax 18's and a inuke 6000dsp will be here this Sat. I'd like opinions on which end of the spectrum to chase. I've designed 2 separate boxes in winisd and now need help.


First a few things that I think are most relevant. My mains are klipsch rf-83's which "should" respond down to 29hz, but at what spl I don't know. I have no measuring equipment yet. My room is a multiple purpose theater room that is around 6000 cubic ft. with the majority of the room having a vaulted ceiling with 4/12 pitch going from 8' on the sides to 12' in the center.
design box 1(red):
12ish cubic feet tuned to 15.5hz
1300 watts to keep excursion around 22mm


design box 2(green):
8ish cubic ft tuned to 20hz
2000 watts for excursion around 22mm





Which slice of hertz pie do I want to eat? Listening is 90% movies and 10% music. No WAF factor for the boxes and will have a several options for placement around a 22x25' room.


Clearly given my room size, a bass head may suggest 4 or 8 or 16 subs, but these 2 are it (for now)


Any assistance would be appreciated. Please let me know if I left out any variables.

Go with the lower tune, you already said that you mostly watch movies.
Also just because your mains manufactures specs list is down to 29hz doesn't mean it'll actually play that lower with any real output. I would not cross those speakers over any lower then 60hz to your subs IMO.

Thanks for the reply. I'm leaning toward the bigger box with lower tune.


The "suspect" or "unknown" low end output of my mains is my reason for considering the smaller box higher tune. My thought process being that I could cross the mains over a little higher and let these two new subs handle the midbass at a much higher SPL and only be sacrificing a few SPLs at the low end of the hz spectrum.


the small box really rolls off hard past 20hz but it still charts at 112bd at 15hz, which I think would be find for my realistic desire of say only 100db at 17hz for a movie.


Is this though process out of line? should I keep the big box if nothing else for more head room? The small box excursion limits me to about 17hz. How much stuff would I be missing without being able to go below 17?

I say build which ever box you can live with, as far as missing out on content below 17hz; well that always seems to start an interesting debate. For me personally I wanted a port tune of 14-15hz know that I'd still have somewhat decent output at 10hz but also knowing that I wouldn't have anything useful below that. Some take the same approach with 18-20hz.




Personally I would cross your speakers over at 80hz and let the subs do the rest, there's no way you mains will keep up below 80hz anyways.
