I had seen that after I commented. The same issue exists with the Corsair. Subwoofer is being deleted. I'm guessing it's a supply issue.
Same problem exists for both vehicles.
Hi Cuemark. Yes, there are several existing threads concerning the parts and commodity shortages with the Corsair. As you just stated, and as with other current parts/commodity shortages for many manufacturers, it is a supply issue for the "Premium" (base) audio system sub-woofer in the Corsair.
Since the discussion here was concerning the Aviator, I just did not want other members confusing the Corsair audio options you mentioned (no Revel Ultima 28 speaker system available) with the Aviator, which does offer the Revel Ultima 28 speaker system as an option.
Good luck.
