Large boxes just aren't commercially feasible due to people's prejudices about audio components (our wives, specifically), and due to shipping costs. Small subwoofers can be made to work well, but they need a LOT of power and some expensive driver construction. Most people just don't have the kind of bass that DIYers are capable of achieving, and they don't know what they're missing.
I just want to reiterate Joe's statement. This is so true. I just built my first subwoofer after many years of building regular speaker systems.

I have heard a lot of in store subwoofer systems. Including Carver 1000 watt small cubes, Velodynes, etc.

This four cubic foot 1.5 inch thick double shelf braced cabinet that I made for a modestly priced Dayton 12 inch subwoofer driver just kills by a wide margin anything that I have heard in a store. And with the amp I'm only into the whole project about 250 USD.

Just an update for anyone thats interested (a moderator should probably move this thread to subwoofers heh). The peerless CSX woofer was no longer availible, and a 12in SLS replacement was only marginally more expensive. (the old polyprop 12in availible didn't have so much copper in the moter i believe). So we went for the 12in driver. Differing parameters and enclosure size restraints mean that this one will be going sealed, 100 litres or so heavily stuffed, hopefully to get a Q of around 0.707. F3 should be about 40hz.

Hi noodle_snacks,

Try the SLS 12 in the same box as you modeled before, 100l 23Hz.
Not to bad, good power capability down low. Damped tuning.

Easy to block port if one want's to go closed box.

Herein lies one of the biggest problems in buying any part of the speaker system. You have to buy it from a store and don't hear it in your environment.

It's not fair to compare the two. How you implement the system into your environment is a huge factor. IMHO, second only to the speaker(s) itself.
