I'm just wondering, how do companies like Bob carver or sunfire get there subs very low like around 18-25hz in such a small enclosure. I see some subs that is only about 12in. square sealed box that get's crazy lows. I ask this because I am looking to built a home sub for my house and I want it small but still be able to get nice lows.
They claim 59mm p-p excursion. I'm not sure if that is xmax or xsus, but it's a lot for a 10" driver!
They use passive radiators which allow the smallest box with 20 Hz extension.
The distortion is probably quite high.
If you want to do better for less money and don't expect it to be quite so small:
* get a high excursion driver like the Stryke/AE AV12
* get a pair of 15" passives
* put it in a reasonably sized box
* 500w plate amp
* BFD for eq
When you realise the price you pay when you make it very small, you will probably want to make it bigger.

A Peerless XLS with a passive radiator a small box will get down. I have a 10" version that measures flat deep into the 20's in my office. Search for XLS and you will find a ton of hits. There's a new version called XXLS too.
The 12" needs a box that's about 1.25 ft^3 (35 liter). The 10" can go in a box as small as 20 liters nominal. When ordering the passives, be aware of how much moving mass they have; There are two versions of each PR. Of course, if you get the lighter one, you can add mass by attaching washers or whatever.

What is your budget?
Forget passive radiators then. Either go with a small sealed box with a Linkwitz transform or a larger vented box.
The AV12 is on pre-order at the moment for $140 USD. That will match an XLS passive radiator sub in output but with a sealed box. It is also cheaper at the moment than just the XLS on its own.
The Shiva isn't much cheaper. If $140 is too much then I'd say start hunting around for some special deals. You might find some on clearance.
You could also look at Dayton DVC for $105 or Quattro for $75 at Parts Express

Check this out Stryke Audio Clearance items
eg. 1 SAE1201. Basically identical to a shiva but with a single 4ohm VC. $60 for that one. 15mm xmax
If you can pick that up it would be a great deal
Not sure if it's still there

This is going to be my first time building a home sub, so I dont want to spend a lot of money. Once I get more experience I'm going to get better equipment and built better subs. I already bought those Dayton and an Audiosource amp. I've read from a guy that it is rated 50W @ 8ohms, I'm going to be running @ 4ohms, hopefully Ill be gettin a little more power. So basically I just need to figure out what's the best enclosure to go with.

paulspencer said:Now it's time to plug in some numbers into Win ISD (pro is best). You probably have 80-100w into 4 ohms. You might consider making it a vented sub and see how small you can make it, since you don't have a lot of power on tap. If you have a go and post some sim results we can give feedback
this is what I got. It is in a 1.3 cu.ft tune to 30hz
