[QUOTE="Buck, post: 8724434, member: 591582"] The rear chamber still needs to be large enough for the drivers to extend themselves. The rear chamber typically still needs to be close to the recommended airspace. If it's too small, you're going to have a severe low end roll off. Those B&C's are definitely not like most subs, though. But the rear chamber doesn't combine with the front chamber airspace quite, because you have the rear port that individually pressurizes the rear chamber. So the rear chamber needs to be big enough. With many series 6th orders, the front chamber can widely vary. Like you don't even have to try hard on the front chamber because the rear chamber is what matters. The front chamber can be small or big have a loading wall that's tuned or literally just a wall to shrink the opening from the front chamber, or even no wall at all. The front chamber on a 6th order is very similar to how you would add vehicle's cab into the equation, except for the rear port/front port relationship. Like you wouldn't make your rear chamber too small just because you put it inside of a car. [/QUOTE]
