Small Living Room, Box Design Help. Sub Poll Added.

Alright guys, I've got the wheels rolling on my new setup:

Receiver: http://www.crutchfield.com/p_158STDH540/Sony-STR-DH540.html

Sub amp: http://www.parts-express.com/dayton-audio-spa500-500w-subwoofer-plate-amplifier--300-807

Sub: http://www.parts-express.com/dayton-audio-um12-22-12-ultimax-dvc-subwoofer-2-ohms-per-coil--295-512

or

http://www.parts-express.com/dayton-audio-ts320d-4-12-titanic-mk-4-subwoofer-4-ohm--295-403

First off, I am leaning towards the ultimax, the specs seem to indicate it will get lower. PLEASE, correct me if i am wrong, Im new to this home audio thing. Id like input on these subs, and other recommendations are welcome, as long as you can explain why.

Second, I'd like some help on the enclosure(for the ultimax, for now). I know tune low, but how much airspace and how much port? The living room is only 14'x14' with a 9' ceiling.

All help is welcome!!!

id reccommend a 4th order. to get an even amount of bass in a living room you need loading walls just like in a car. tune low is good. id say for movies and stuff like that tune around 24 or even down to 20. for music tune higher 20s. port area is a function of the driver. im not too familiar with home enclosures but im telling you what didnt work with mine. high tuning wasnt good. and to get descent bass i had to put in corner and aim at wall. thats why i reccommend a 4th. jsut stick to around the port area youd think you need for a car setup jsut tune lower.

airspace and port same as car. jsut optimal for the woofer.

Considered a 4th, but with my lack of experience, Id rather start with a regular ported design. The subs listed have pretty low Fs's for 12s, and I have a good corner in the room for a good size box if needed.

for some reason i think you were born while an earthquake happened and you have wanted to create your own seismic activity ever since.

and Ken that is a nice setup I am also tuned in for this. might have to do this for my living room.

oh yes i forgot. downfire is good.

Downfire for sure if he has wood floors. If carpet downfire onto wood base of sub. Carpet eats bass in a house. Behind a sofa against the wall works great. If not ford into corner.

Floor is carpet.
