Google Auto Trancefer. Klipsch Jubilee and JBL DD67000 comparison and new product ideas for speakers. Aon CEO Masahiro Ishizuka.

The Klipsch Jubilee is a 17.78cm (7inch) titanium diaphragm tweeter driver. 

Double 30cm woofer. 

If you want to develop a higher-end version of this speaker, 

you can develop and research the above tweeter with a diaphragm made of pure beryllium, cellulose nanofiber, 

or artificial diamond, and if the sound quality is better than a titanium tweeter, 

you can incorporate them and produce it as a new product. 

I think. The squawker of JBL DD67000 is a 10cm beryllium diaphragm tweeter driver and  

2.5cm beryllium diaphragm super tweeter driver. 

Double 38cm woofer. 

I think the sound quality would be better if JBL also made the tweeter and super tweeter larger and used a vertical 38cm double woofer made like Hartsfield and stopped using Gold Wing, but this may be just an amateur's opinion.
