I was referring to the previous poster's Boston A-40's lack of an inductor, not yours. And the only way to tell the crossover's actual acoustic order is to measure it. It's important to understand that regardless of the ELECTRICAL order of the filter, it's the ACOUSTIC result that defines the crossover.

Ah, good clarification. So a first order crossover could very well achieve second order or third order slopes with help from a cabinet design. What eludes me is what effect this has on phase.
You'll get second order from a sealed cabinet, 4th order from a ported one. It still doesn't seem like you're able to differentiate between electrical and acoustic crossover orders.

What do you get from a transmission line, 1/8th wave, which reportedly is not possible? I am not affecting some scholarly knowledge of acoustic engineering, I am trying to make some measurements and have a real look at a set of speakers that are sitting in my living space at the moment.
Let’s say, for arguments sake, that the tweeter is in a sealed box, as many are, then we have a technical marker for the designer’s claim that the design is transmission line/acoustic suspension hybrid. Beyond this, transmission line provides some of the back pressure of acoustic suspension, but is not acoustic suspension as the porting provides a momentary pressure that is dissipated through the transmission line.
What I would like to comprehend at the moment is how these design parameters influence phase.
Thanks for you input. Please keep it coming.
