Can I do a Jordan Jx92S in a .75 cuft cabinet?

stephenmarklay · 19th December 2009, 03:20 AM

Standard ol PE .75 cab just needing a build. I have seen little boxes like .25 an the larger free standing.

Can this box work for the driver?

Yes.

You can go with one cubic kilometer also. There are tradeoffs with any volume.

Whoa NP! InclinedPlane - is this 22liters a pour choice?

My basic box software suggests a port 2" by 7" for that volume. That should get you as low as 45hz.

Your volume is larger than the maximum volume Jordan suggests for that driver, but a bigger box like that .75 would be my choice also. I like deeper bass.

With a relatively large box like that, you will lose some excursion-limited power handling as a tradeoff for that greater bass extension. When a fullrange driver goes into over-excursion the first sign is usually a loss of midrange clarity.

The Jordan is a pretty hardy little sucker. If you're
reasonable on the volume control, I think it'll be fine.

Sorry for off-topic, but something just popped up in my mind: Nelson, if I remember correctly, once you mentioned that you were experimenting with a cheap (ok, that's relative, but cheap for what you get) combination, which consisted of fairly good fullranger in a closed box (like Jordan driver) and some cheap (again, relative) subwoofer, and, that you will write a paper about that, the point being that the combination will be WAF friendly and give a bank for the buck. Ok, I admit that Jordan is not a particularly cheap driver, but in the above combination, the sound would be much better that some mass-market offerings...

Am I wrong?

Thanks..

On topic

Looking at the distortion profile down low it likely is better to use this in a smaller box with a natural roll off at a little higher freq.?
