Hi JPM,
Any subwoofer, not just Axiom's, interacts with the specific dimensions of your room, its boundaries (the walls and floor) and the seating area and its location in your room. Those factors will determine how much bass you hear, and how smooth and deep the bass will be.
So you have to experiment with a sub's placement. Generally speaking (as others here have noted), it's really unwise to put any speaker, with or without ports, into an enclosure. Bass frequencies are largely omnidirectional, which means that they radiate in waves outwards from the speaker in every direction. Imagine throwing a stone into the center of a pond-- the waves radiate outwards in concentric circles from the point the stone hit the water--that's exactly how bass energy is dissipated from a subwoofer.
That's why you don't want to pre-determine a spot in your room for a sub, especially inside some type of enclosure.
Regards,
Alan Lofft, Axiom Resident Expert (Retired)

Hmm, I wondered about that but then got to thinking a thread devoted entirely to the sub had been started and Ian himself had chimed in (albiet the spec.s weren't referenced).
*laughs* I was kidding.

Thanks for all the replies! I still have a few questions though! First I will give a description of where the sub will be placed. The area is 20' x 25' x 8', this is why I am interested in the EP500 "Usable" area is a premium and this is the reason why I am asking if it can be place in an entertainment unit. If a sub EQ is used, does placement matter as much? I read through the manual and it doesn't state that the Sub cannot be placed with in an enclosure. Here's what's marked in the online manual: Cautions: 7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. Precautions: 5. Heat/Ventilation - Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of the product to protect it from overheating. These openings must not be blocked or covered. This product should not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided or the manufacturer’s instructions have been adhered to. The product should be situated away from heat sources such as radiators, heat registers, stoves or other products (including amplifiers) that produce heat.

Oops forgot tho mention one more thing.
The entertainment unit would have an open front for the sub and its port.

If you read Alan's response, that explains why you don't want to place a sub in an enclosed area. Lowwwww frequencies, say 80hz and below, are omnidirectional. They radiate in all directions not just forwards. Also, the sub is affected by room characteristics, room size, furnishings, etc. Placing it in an enclosed area will defeat the purpose of having a sub.
Can it be done, yes. Is it wise, no.
I still don't see with that size of room, why you can't find some location along a wall, behind a chair, etc. to place the sub. It does not have that big of a footprint.

It's extremely difficult to properly EQ a sub in an enclosure. The sub interacts with the enclosure and the room both. So, as you EQ, you may correct for the enclosure but mess up for the room or vise versa. Basically, you're going to end up with WAY too much EQ with results that may be... disappointing.
