Is ok to share just one chamber for 2 drivers? Cause some dual br designs are basically a single cab design just welded together as one cabinet but discreet chamber for each driver.
Yes, there are many good projects with drivers sharing chambers, why it would be a problem?
The negative side of multi drivers solutiosn is regarding driver failure, the drivers that remains operational will work in a oversize box, you can simulate this effect with hornresp turning off one driver to see the responds 1 vs 2 drivers in the same box. Maybe the drivers that failure can work as a passive radiator too, it will depend from the failure and the box design.
If you have two individual boxes, the failure might bring effect only in the max SPL. Take a look in the attached project. Two boxes combined into a single box, but they work individually. They will be heavier to transport, but you save some woods to build them.
You can't have discrete chamber using dual driver, if the camber or the vent communicates, it will move air from one to another. I don't know the benefit of shared chamber design, I never investigate deeper, but it won't be hard to get the answers.
Sansui,
I get how individual boxes behave, the design you posted are 2 cabinets sharing a side so practically is like having 2 single 18's next to each other ,but how do you input in hornesp a dual reflex cab sharing the same chamber for both drivers. See the attached pic that I took YouTuber Mr.Flexy .
