which box type is going to give the best bass response for a SQ setup?

I was looking @ an RE XXX driver.

Thanks

It all depends on the subwoofer.. Most are designed for either a ported or sealed box, but often sound better in one application, over the other. I've always liked sealed boxes, however there are many SQ systems utilizing ported enclosures, that sound great.

I'm not too familiar with that woofer, so I couldn't tell you what would sound better.

I have had good luck with sealed and they are very good. The ported boxes, if properly done, give more output and maybe better snap, snap, er transient responce but I have always found sealed easier. That is a poor reason to choose, but it is harder to screw up a sealed enclosure. Is ported superior... I think that may depend on the drivers used and the box you use.

As said, depends on the driver. Both can sound awesome in an SQ system. I've always run sealed but my DLS UR12 likes ported, so now I'm running a ported sub in my SQ wanna-be system

are we ruling out bandpass here altogether? [img]graemlins/dunno.gif[/img]

Bandpass boxes play loud as hell, but I have yet to hear a really good sounding pass box. I find that they lack impact, and generally sound boomy. Depending on the design, they usually have a farily bumpy frequency response curve as well.

General rules:

Sealed boxes roll off slower, (12db/oct) than ported boxes, (24db/oct) therefore easier to get extreme low bass from a sealed box. It is hard to get much output below the tuned frequency of the port. That being said, you could tune the port at the 3db down point and extend your bass with the port.
Bandpass boxes are not just loud. Draw triangle, putting the following at each corner; loud, low, power handling. Now put a joystick in the middle. If you want more output, you give up low bass and power handling...nothing free here, but you can get more of what you want, e.g. deeper bass than sealed or ported, (just no power handling or efficiency.
I personally like sealed boxes because they tend to have better transient response and they handle a little more abuse, (equalizing...).

i've always had good luck with sealed boxes. they always seem to sound good when the box is properly sized.....like stated before though, it depends a lot on the sub.

The bandpass design is to work a portion of the freq range and pump out more output. That is not really what SQ is about. I mean at best what does a true sub 120 to 20 Hz (90 to 20 Hz in most) that’s already a pretty limited band. Porting is the oldest HiFi technique and it really can do more with less.
But the point is not which box is better but which matches your front end best.
