So i have a 500w bash plate amp i'm going to be pairing with a dayton titanic mkIII 12inch. This system will be in my room at home for now but will be going with me to my dorm next fall, so i can't have a huge box. I would like to go ported as i am a huge basshead thx to my car audio experience, but i don't want it to be sloppy for music listening. From what i've gathered most HT setups feature lower tuning so it shouldn't be a problem.
The other thing i've noticed is that many HT boxes use tube ports....is this a must??? i am more apt at boxbuilding with slot ports...wondering if there's any reason not to slot port it.
So basically what i'm asking, is how big of box, what tuning, what kinda port i should use, and where i should place the sub (down firing, on same face as port, on opposite...etc). help would be appreciated!
400dB could probably d...,

Too Many DBs...

How you put your sub (down-firing, fron-firing) depends on if you like the shake more or just hearing it without the shake. I don't even know my preference yet. Nothing is wrong with slot porting to my knowledge. I'm considering infinite baffle (different in house than car) for my setup as it provides the benefits of being musical, having high efficiency (SPL), and not intruding into the room. Have you ever heard of this?
I see no reason to buy a cabinent when i can probalby make one (or 2 actually lol) from a 20 dollar sheet of mdf.
As far as infinite baffle goes..in car audio that usually means no box basically free air which never really optimizes anything. I want to here it most...the shake is a plus but not what i'm going for i guess....
Guys, neither is "true". Not all drivers can be mounted in a downward firing position. It has to do with the suspension of the driver and not your user preference.
Jan, I know that the suspension of the driver has to do with it as well, but there are some people that feel that a downward firing driver has better dispersal, and couples with the room better.
IMHO, I have heard both well (and very poor) examples of both front and down firing designs.
Two of the MartinLogan subwoofers are designed so the user can mount the sub either in a floor firing or front firing configuration.
Maybe it's just me. The salesman for the woofer says that it can be mounted in any direction. This means that it has no use for phase, first of all. It will work just as well with its concave reflective surface facing a cushioning space of air, as it will facing a counter-reacting force of exact energy. Each of these arrangements can deliver the frequencies available through an extruded aluminum basket, when the rear of the speaker is pointed toward the outside.
Josh, Couple of things may help. I have the printout of the advert of the MkIII in front of me. In the small print at the bottom they say 1.1ft3 sealed OR 2.8ft3 vented. There are tradeoffs in either choice...power handling and low freq rolloff are just 2. There are several 'box' programs available. Some are free and others can run 100$ plus. You may want to try some of the freebie stuff first, to get an idea how the numbers (TS parameters of a driver) effect the final outcome. As it turns out, I'm in a similar boat, trying to figure out how to get some real bass going in my system. My ancient Maggies give up around 50hz or so. I simply don't have room for a full-on HT setup, so I want a sub for music as well as the boom-boom stuff of movies. Welcome to the DIY Zone.
