$700 budget ported Sub + Amp

I'm looking to build a subwoofer and would not like to spend any more than $700 total (DSP, Driver, materials, maybe AMP)
I have a 160+160w 4Ohm Amp avaliable and would like to use it but if you think I should spend the money on the amp then I can.
I'm not really sure what my options are, I live in Australia and am happy to buy off Ebay http://www.ebay.com.au/

A few things with the driver:
1. I would like to have a box roughly 5 cu. ft. or smaller
2. The room is ~4x5m, I don't need anything too crazy
3. 12" preferred but am happy to go bigger if it is within the budget
4. Budget is very important, can't justify spending more :(
Used for home theater but 75% of the time will be music
*Happily will go bigger driver and box if it can be done within the budget*

also would the miniDSP be a good high pass filter for this?


EDIT: Have been having a bit of a look at this: http://darcheraudio.com.au/store/ind...roducts_id=119
The CSS SDX15 15", Thoughts?

That is an excellent driver, for your needs it would work well in 4 cu.ft. with 1000 watts.

Re: $700 budget ported Sub + Amp

Just wondering, is there any reason you went with a sealed box as apposed to a ported box?
Also because the sub is $400 I don't really have enough money to buy an amp so I will have to use the 160wx2 4 ohm amp that I have.

EDIT: Oh wait I didn't realise it was 2Ohm per coil, I don't think my amp can handle that. I think I need to look for a different sub with 4Ohm per coil (or a really really cheap $200 amp that can handle the load)

You could try to source a used behringer ep 2500 or 2000

Do I need a subsonic filter for this sub if it is in a sealed box? If I don't, I could afford a behringer iNUKE 1000 which should work alright.

What receiver ate you using ?

Yamaha RX-V461 http://usa.yamaha.com/products/audio..._u/?mode=model

a friend with a Denon receiver that was about $2500 4 years ago (not sure what model) is giving me the receiver when he upgrades within the next 6 months (the HDMI processor on it has died)

I would prefer not to spend money on a new receiver with this coming in the next few months.

No subsonic filter needed for this sub being sealed. Porting this sub would require more then the 5 cu.ft. you stipulated.

Re: $700 budget ported Sub + Amp

I think I will go ahead with an EP1500 + the CSS SDX15 15" in a 4 cu. ft. sealed box. Are there any known issues with this amp?

Re: $700 budget ported Sub + Amp

The Behringer EP series is known as the best bang for the buck. A 4 cu.ft. net volume cabinet would be a 21" cube measured externally using 3/4" material.
