dspMusikLCD crossover for JBL M2 speakers
« on: 13 Oct 2017, 08:57 pm »
Have a request for a dspMusikLCD digital crossover for the JBL M2 speaker system to use instead of the Crown amps the original crossover was created to run.  This will be for a demo once the system is setup.

Have the prototype block diagram completed and running. Next will be testing the response to see if this matches the reference curves.  Will setup Pocket CLIO for taking the response data.

Have a JBL M2 owner that is interested in a demo, so will finish the setup and measurements for the system and get it ready to ship for listening trials.

Once the final crossover is decided, will post response plots of the dspMusikLCD version.

Rich, you should consider sharing this info with the folks at Lansing Heritage. There are members there building diy M2s. You should probably introduce yourself to them as most there won't have any idea what you do. http://www.audioheritage.org/vbulletin/

Rusty,
Thanks for the info.

If the JBL M2 demo goes well, then will post on the site.  I have no way to listen to the M2 speaker system, so if the results are positive, then would make sense to let them know.

M2 DIY movement was stifled when JBL shut down the parts supply to non M2 owners.  :cry:

This might help you Rich, fwiw: JBL M2 crossover settings

Rich,
Thanks!  :)

I used that to make the prototype, so should be close.  Have to use a different approach for some of it as it is proprietary to Crown.  Will use the alternatives suggested in the paper.

This should be interesting!
