Andy, it looks like you blew up the world again. :rolleyes:
These use the peerless drivers and are very cheap... https://secure.wilmslow-audio.co.uk...03_80&osCsid=7591765cd7524bf5678b1b536f4ca260 https://secure.wilmslow-audio.co.uk...id=45&osCsid=7591765cd7524bf5678b1b536f4ca260 http://www.vikash.info/audio/xls10/
I would go for the Vikash design and stay away from ported subwoofers if possible. IME sealed is even better but passive radiator will still be good. You may also consider this - http://www.linkwitzlab.com/woofer.htm
Sorry dude though you were taking the p*ss. Have avatars switched off and forgot all about it. Post edited
If you have eq would it matter if the sub was ported or sealed so much? I used a sealed 8" in my car, due to the low end cabin gain you get in a small space. This keeps things more linear. Although I thought a larger space like a room might be much more forgiving?
If you have EQ and can take meaningful measurements then yes, you can go sealed and still get deep bass. Thats something I have done. But you need a woofer with good thermal power handling (so the voice coil doesn't burn out) and a load of power. The woofer can go as deep and loud in a sealed box as a ported one, provided the voice coil and the amps can deal with the power required to do so.
