Default Jordan jx150ng

Hi, i have been looking to build some speakers and have decided to go for jordan drivers. My wood working and soldering skills are good but unfortunatly i am completly lost when it comes to crossover design, cabinet size etc.

I came across this design-

http://documents.jordan-usa.com/Encl...ed_cabinet.pdf

The drawing and crossover layout are refering to a 30 litre enclosure whilst the frequency response graph refers to a 50 litre box with different value crossover components.

Any advise on enclosure size and crossover values greatly appreciated.

Thanks.

It would seem that the crossover is reasonable for either of the three enclosures.

A larger enclosure would relax the bass a little, but it would reach lower in return.

Are you going to use the JX150 with the JX6 or do you plan to use a classical tweeter?

This xover is a very special one and requires wide band drivers on both low and high ends since the JX150 is crossed at about 2khz and the JX6 at aprox. 200hz. This designed is not aimed at real tweeters, just suitable for full rangers like jx6.

Yes, there is a big one decade overlap in this xover designed by "the man who hates xovers" aka "the father of full range"...

Thanks for your replies
Yes , the plan was to use the jx150 with the jx6.
Would you say that this design would make for a good pair of speakers?

What makes a good pair of speaker for one part of human kind, also makes an awfull mess for the rest...

Be sure i own them though...

Difference for difference sake is not necessarily any virtue, and this would be my main grief with the father of excentricity...

Nothing to wonder about...
