question about 6th bandpass front tuning

[BP1Fanatic]

Yeah, about the same but my rear port is inside the front flare. Series tuned offset front horn? Now simulate that on hornresp

The build pic in post #35 is not reflecting a series tuned BP6. It looks parallel tuned.

Also the rear chamber port is very (too) long.

I thought globalplayer understood my 1min made schematic

This is a 4th order now?

but then he hit it with this...

there it is, 162cm2 port
