Okay why does the 300 have a bigger woofer but cost less and then why does the 400 have a smaller woofer but the box isn't ported in the front and it cost more? Is that cost just to add the crossover function on the sub?
Why isn't it ported?
And before you ask I can't afford the 500 model.
For me that is way to much money to spend on a subwoofer.

Thanks

The 400 has a fancy computer controlled amplifier and it won't distort if you try to play it too loud.

The main reason for the cost difference despite the size difference is that the EP400 employs DSP processing which gives the designer much greater control and performance advantages. Basically if you add the DSP to the EP350 you have an EP500.

If you are looking for extension and have a small/medium size room swing for the EP400. The EP350 will likely be able to provide more output across its frequency range for larger rooms.

I wouldn't even say medium rooms. Axiom promotes it for small room only.

For the large majority of situations, the 350 would be the better choice. The 400 is something of a special-use product.

I would use the 350, unless you have a very small room. I'm very happy with mine.

Sealed subs often times sound better than ported subs, seals subs also require more power than ported as well, this is due to the driver compressing the air inside of a sealed box.. In a ported design the air is allowed to escape reducing the power needed...

Probably one of the biggest advantages of sealed subs is that it eliminates port noise all together at high output. Port noise can sound like "flapping" or "farting".

I also believe the EP350 has a 350 watt amp, whereas the EP500 has a 500 watt amp. (Not mentioned in the comparison above)

Cat, i am almost positive the naming scheme (the number) among the subs is how much power they have.

Not quite but close the Ep400 has the same 500W amp as te Ep500 but the DSP is a little different for the smaller enclosure/driver. The EP350 is 300W, so there are some minor differences.
