Ok, so transient response suffers with 6th order bandpass. Maybe I should just stick with reflex then.
Hmmm , what about a big vent reflex? Is the yorkville LS808 a back loaded horn or just a big vent reflex?
The advantages of a large port/vent is the ability to pass the audio without chuffing or "shutting off".
If the port is to small, it will make various noises at higher levels (chuffing) and could possibly actually cut off or choke the cabinet-more or less turning it into a sealed box alignment.
The downside to a large port is that it MUST be longer/deeper. So the cabinet size gets larger.
You you have to weigh the performance vs size issue. In most cases the performance side is the one that "takes the hit".
It is all a matter of trade offs
