Just a thought: it's possible to do some tone-shaping with crossover components etc. For example, that 5" speaker shows another octave of HF extension compared to most guitar speakers, so you might consider adding an inductor to roll off the highs a bit.
A 2nd-order (or higher) slope could also be considered.

This is a great idea. You could also filter the midrange for a more modern sound.
Yes, Jensen Mod 5-30 has rather extended high frequency spectra, and notch at 3 kHz is also an octave higher than optimal. The first thing to do is to try to tame highs with amp treble tone (and/or guitar knob tone) control. If it is not enough, then low pass filter with inductor, eventually plus capacitor. Foam in front of the cone will do the trick also - I think 1 cm thickness was the best, but it was long time ago when I tried it and I didn't saved the measurements.Just a thought: it's possible to do some tone-shaping with crossover components etc. For example, that 5" speaker shows another octave of HF extension compared to most guitar speakers, so you might consider adding an inductor to roll off the highs a bit.

Sonce,
The original poster stated they want to use a valve/tube output stage and drive it into distortion, so the resulting spray of harmonics will come through the speaker regardless of the tone control's position.
Acoustic filtering is a quick-and-easy solution, though. Some measurements and trial-and-error, but I think that'd work nicely.

Yes, overdrive/clipping will generate distortion - more harmonics up in the high spectra. But the point of my post is to shape frequency response of that overly bright little driver to be more similar to well-regarded bigger drivers, not to try to filter out harmonics. So, with frequency response shaped that way, when distortion is provoked the harmonics quantity will be similar also.
A situation where using a more 'HiFi' type speaker may be better is when using a 'Guitar synth / sound modeling' situation >

Can someone elaborate as to whether things such as the GR-55 are meant to 'connect' directly' > FLAT to the recording mixer input ???

It has arrived. I asked some to make the box for me and apply varnish. This is the result.

I tried the amplifier yesterday and it sounds great and loud !
Thanks for your support!
Kind regards,
