Featured Article: Enclosure Vented Port:

Let's start out with the first thing you'll notice, other than the valves Hulk green valve case (we'll get to that in a second) the four full 3/4" ports. Two (2) inlet ports on the left and right, one (1) outlet port for the shower and one (1) for the tub spout. This is significant because most valve companies offer their valves in both 1/2" and 3/4" version depending on the piping size of the home or the volume of water needed for the shower.
What if the water piping is 1/2"? Do I have to buy extra fittings to accommodate the valve? Nope, the 3/4" x 1/2" bushings are included in the box.
You'll notice that at every port there is a black rubber seal. This valve itself is protected against leaking at all its connection points in fact the entire valve is sealed by the green enclosure. If there is a leak within the valve or the connection points the valve will leak into the box and exit through a weep hole on the front of the trim kit.
The next point of interest are the valve's integral stops. Having integral stops on a tub/shower valve allows you to change the valve cartridge or change trim without shutting the water down in the entire house, or close an isolation valve in your home or condominium, if you're lucky enough to have them. Having integral stops sounds like a logical feature to have on every tub/shower valve right? Valves are cheaper to build without integral stops. Hansgrohe doesn't give you a choice anymore and for good reason, they've made the rough-in valve affordable enough to remove the option. You get them standard whether you like it or not.
There are other benefits that we will list but by far the greatest feature is the valves flexibility. It is a pressure balanced shower only valve (the plug for the tub is included in the box), it is a pressure balanced tub/shower valve, it is a thermostatic valve with volume control for a shower, a thermostatic valve for a tub/shower and thermostatic valve with volume control with a diverter to control two shower functions.
How and the heck can one valve to handle all these features? With the trim and cartridge. It is literally a "plug and play" valve. You can get a trim that is simple and affordable or opt for a fairly complex trim set with a full line of styles and finishes. If you wanted to install an affordable trim set but wanted to upgrade at a later date the install is quick and easy.
The significance this valve has on the home/condominium market is profound. Picture a spec housing subdivision or a high rise condominium complex. There has to be a building rough standard. Now the builder or GC can install this rough-in valve with a certain measure of confidence, that they can offer a trim set with a style, features and finishes that can accommodate the majority of their prospective customers. In the past the GC and plumbing contractor would have a standard set of plumbing rough and trim. On many occasions the buyer of the home or condominium would choose something completely different and the plumbing contractor would have to tear out what was installed. This happens more on high end residential but this valve takes those headaches out of the equation.
Here are several other features that make this valve a truly unique product.
The iBox valve can handle water from 6 GPM to 16 GPM. So the need to upsize the valve to accommodate a couple body sprays is not necessary.
Because of the valve configuration and its pre-installed test and flushing plug the water piping can be tested and flushed without the trim being installed. (We'll explain this further and insert a picture of the valve without a trim cartridge to make this more clear)
The valve housing has multiple mounting options. The valve enclosure has leveling points to make sure the rough is level in both directions
Depending on the plumbing wall thickness the valve enclosure can easily cut to accommodate. The next time you are in the market for a shower valve give this one a look.
Sincerely,

The Floor Standing And Wall Mounted Data Cabinet
The challenge facing many businesses today is how to run data servers and related hardware in an efficient way without overloading thermal capacities of these devices. The amount of power needed to drive storage units, servers, and routing management devices that are used in today's online business community can become a cost-deficient equation, when combined with the cooling systems needed to keep the data center running trouble-free. Systems that run in an unconnected environment will waste power through excessive cabling, and those systems that attempt to reduce patching by piling devices together in what can be described as a haphazard manner will eventually have overheating issues.
The importance of a sensible, practical, and compact data center cannot be stressed enough. That is where data cabinets comes into play. This is not a new concept, yet many of the cabinets in use today are outdated as far as their ability to handle newer hardware that is continually needed to keep up with data control needs. Another issue with existing data cabinets design is their inability to contain upgraded device configurations in an energy-efficient manner that can control thermal conditions to a useable level. The network can be connected together in various locations around the infrastructure by a wall mounted data cabinet, usally housing small active equipment or patching arrangements.
In other words, the data center of today needs data cabinets that are flexible enough to handle changes in device installations while still allowing for ease of cabling and maintenance, all within a design that can handle the increased heat that is created by those devices. Any equipment that dispapates a susbstantail amount of heat would not normally be housed in a wall mounted data cabinet.
The first important feature of well-designed data cabinets is access. Loading a cabinet with hardware is one thing; leaving room for multiple cabling applications and maintenance is another. The best designs will have access doors and panels that will allow the user to open the cabinet in different ways, either to get at the devices themselves or to change patching configurations. A functional front door setup be hinged on both sides of the cabinet, and will be properly vented. Some of the better designs will include the option of a split-door style, much like a closet door that opens in the middle to allow access to the center of the cabinet, while also opening on the edges to allow access to the patch bay.
Of course, the patch bay is critical in all data cabinets including wall mounted data cabinet enclosures There must be an increased ability to change cabling configurations, allowing for both fiber optic and copper ports. This will be best addressed by having the central patch bay directly in the center, so that cables from routers, servers, and mapping and analyzing devices can be connected in one spot. Patching flexibility should also allow for both vertical and horizontal port configurations so that system devices can be changed out or relocated as the need arises.
Other important features of effective data cabinets include access door designs that are thermally-minded, drawing in cool air while removing heated air; rack-mount designs that allow flexibility and room for growth; and blanket panels that not only fill in any empty spaces between devices, but also maintain interior temperatures to a safe operating level.

What should the square inches of port area be if making a vented enclosure tuned to 32 Hz?
If building a vented enclosure w/ an internal volume of 2.25 ft^3 and tuning to 32 Hz, what should be the square inches of port area?? (One 12" Alpine Type R.)
Also, would anyone be able to give me a personal experienced estimatation on the best shape/dimensions, for the enclosure, as far as length/width/height.. What works best in the type of enclosure I'm planning? ....With the subwoofer and vent/port both facing the same direction, is it better to be deeper or longer to accumulate to total volume of 2.25.....?

The best shap to avoid is a perfect cube, other than that there is no limit.
