With a bandpass woofer you have to make a compromise between bandwidth and sensitivity. The smaller the bandwidth, the higher the sensitivity but then the impulse response gets bad. Also i am using a closed box because speakers of the 70th in Germany mostly all where closed and the Peerless woofer i use has parameters for closed.
Ok, i decided on a primer.
I will publish the circuit how it is at this moment and some photos.

Actually i am using 22nF and 15kOhm input impedance on the main amp.
The S1 is set to 300Hz ( maximum ) and i have adjusted the Phase knob for best blending.
I have EQed the woofer by ca. +4dB at ca. 35Hz.
That way the response is from 30Hz to 20kHz.

Today i got the grill cloth. The Fender cloth is more transparent then i thought. The Vox anyway.
Aw, it's a Little Girl With A Guitar (LGWAG) speaker! 😱
Hey, just kidding. 😀
Looks very nice, Joachim.
Joachim I think we've all enjoyed this project. And thankyou for sharing it. 🙂
It would be very nice if you can do a tidy summary at some point. As I see it, you've used a 10" paper subwoofer covering up to 100Hz, with two peerless 5" paper midwoofers, a very good Wavecor 30mm soft dome tweeter coming in at 1.5kHz, and a 22mm supertweeter above 5kHz. All shallow LR2 slopes.
The wide cabinet needs very little bafflestep correction. It all hangs on the quality of the 30mm tweeter IMO: Wavecor TW030WA05-01 (ea.)
Spendor still do the double tweeter arrangement:
Without being disparaging about the look of it, don't you think it looks a bit like someone is drying towels on your speakers? Just sayin'...😀

An externally hosted image should be here but it was not working when we last tested it.

It ain´t pretty, sure. I have ideas to improve the look. I think a grill over the complete front will look better and i would trim the edges with metal strips. The Fender cloth is very expensive so i bought only a small piece.
Crossover to the bass is 300Hz to get rid of the Allison effect.
