Is it 1cu ft air space total, or per sub?

I wouldn't buy this unless your prepared to modify it and re enforce it also. It vibrated apart and I had to put it back together again with better and more hardware. It works now but it needed a lot of re enforcement. And the more air the better or things will overheat and shut down and take a break.

Volume for this particular model is high, something like 120 cubic feet a minute. So, unless your design calls for that high a volume I'd keep on looking. Amazon had numerous capacity fans in their listings.

Honestly, you can't answer that the way it is phrased. RMS does not determine coverage. in a 25' x 22' room one of these could be enough. How many people, what kind of media, what are the room surfaces, what tops are you running, are you using a cross over? All things that need to be considered. A single sub "should" cover a 25'x22' room.

I'd say that's asking a lot from a 12" sub. My suggestion, go bigger and use multiple units (2, 4 or more).

The sub Box you need is a box with a air volume of .80You can make any Design of box as long as it has a air volume of .80 or as close to that as possible I have two of these subs and my air volume for each box is .78 wich is really close to it and it won't make a difference for tht little bit off from .80

Honestly don't know. I only have one sub on my system but I have additional rooms where a sub would definitely enhance the sound. I never considered 2 subs in one room. For rock, jazz, classical one sub does the trick.

two air port of 1/8 of an inch each. Note: any regular air flexible tubing will fit without any problem.

It should be plenty, especially with two subs!I have one sub with a little less power going to it and am very pleased with it.Have fun experimenting, I think that is the best part!

Yes it is, the Sub that I am using is recommended for a 1.5 Cu Ft box and it runs amazing in this box. Having a larger Cu Ft displacement will allow the sound to have more deep thunder bass, If thats what you are going for, but it also works fine with less deep drums and other things like that.

I don't believe square footage matters. It's the amount of air that flows through your system. Almost all residential systems are within the limits.

It is 1U, but you need a 1U rack shelf (it doesn't have ears to rack it with).

Offering another take on Jose's helpful reply... Room cubic feet (WxLxH) multiplied by the number of air changes per hour (N) divided sixty minutes (60) equals the cubic feet per minute rating.WxLxH x N / 60 = CFM quotientYou can find references online on guidelines for the number of air changes (N) per hour. I believe bathrooms are typically 5 to 8 times.So a 5 foot by 8 foot bathroom with an 8 foot ceiling with a desired 8 air changes per hour would be 42.7 CFM (Likely rounded up to 50 CFM)5 x 8 x 8 x 8 / 60 = 42.7 CFM

You would have to look up the specs of the woofer and see the cubic feet of air space required. It doesn't have to be 100% accurate. It just has to be close to what you need.

I have a 30 X 10" and it puts out about 108000 btus with a half inch connection. I have a 3/4" supply line.

I made a fiberglass enclosure however, I believe the recommended size is between .5 and 1 cu. ft. Of airspace which looks like a box about twice the size of the sub.

A good rule of thumb is around 1 CFM per Sq Ft of space for bathrooms provides great ventalation for showers and odors. You can get by with a minimum of 0.5 CFM per Sq Ft but that takes a long time to remove moisture build up.

I have two sa 12's down firing in a box I custom built at 2.19 cu per sub with the ports meeting in the middle facing back. Powered by fosgate 1100a2. Its the loudest system I've heard out of a truck. It flexs my windows
