in reflex loading equivalent circuit, the vent is high-pass or bass-pass ?
since with vent i increase the slope for example in respect the closed box i think it is an acoustical high-pass, but electrical bass-pass
does it true ?
I hope I have asked the question well😱

Thiele described vented speakers in terms of their equivalent circuits, likening them to an electrical high pass filter.
Small elaborated on this by showing that a vented loudspeaker was a fourth order high pass filter.

Perhaps you are referring to a 'single reflex bandpass enclosure' which is different from a normal reflex enclosure.
In a reflex bandpass enclosure, the woofer does not play directly into the listening area. Instead, it fires into a ported front chamber which acts as a low pass filter and acoustically limits the high frequency response.

In the DCR, all three ports have the same dimensions and the primary woofer chamber has twice the volume of the secondary chamber. The enclosure will resonate at two frequencies instead of one. The primary chamber is tuned to a highish frequency, but at lower frequencies the two chambers act as one large chamber providing an additional tuning of half that frequency. This double tuning provides bass reinforcement over a wider band of frequencies than is possible with a single ported reflex enclosure.
Now, what was the question again?

When commenting on the DBR system, even Fostex chicken out of explaining it!

If you're looking for answers based on electrical equivalent circuits, then the next guy who comes along may be able to help. Sorry! 🙂
