If you need the sound of several different kinds of cabs, the idea is that the FRFR speaker will be able to more accurately reproduce all of them than a single guitar cab with its own colored response would. But of course, modeling with IRs is not actually reproducing just sound of the cab: it’s reproducing the sounds of a cab, in a given room, with a given mic, in a given position. I messed with it for way too long. Back to amps.

The top-end response of a conventional guitar speaker will start to decline significantly above 5kHz or so, but there is still plenty happening above that point, just not at the same level as below. If you've ever applied a steep low-pass filter at 5kHz to a recorded guitar signal, you soon realise how important the low-level, high-frequency components are to an interesting guitar sound! It is this characteristic response that modelled speakers and speaker impulse responses (IRs) replicate. Reproducing this response through a conventional guitar speaker would result in, effectively, applying the response curve twice, diminishing the upper frequency components to inaudibility — hence the (to some) slightly counterintuitive need for a full-range system to reproduce a limited bandwidth source.

bandwidth is sometimes counterintuitive ....
a story
i remember years years ago chatting to a physics prof
in the interval of a pub jazz gig
he said he was researching putting the internet down phone lines ...
it was the days of dial-up modems ....
he said they were gonna get 5 Mhz out of a phone line ...
i said no way ..you’re lucky to get 5Khz
i worked in audio with phone lines so i knew what was possible ....
i was wrong ....
you maybe reading this down
the internet on your phone line
right now !

It might also be useful in an acoustic guitar amp, but that’s not how it’s being marketed.
Since Celestion recommends a specific ported cabinet for it, slapping it into a cabinet not designed for it could result in a weird frequency response on the lower end. I think it should be of most interest to OEMs. I’m just speculating.

I like the synthy sounds, sometimes. I have fiber to the modem, plan on living long enough to see what’s next. Directed bone conduction, airborne wi-fi? Don’t know.

While I'm usually drawn to music conjecture and discussion, I will just post an observation involving a Full Range Flat Response (FRFR) speaker with an archtop guitar. The following chain:
Wu Oval Hole guitar -> Sunrise acoustic magnetic pickup -> good pre-amp w/flat EQ -> Joyo American pedal in FX loop (set squeaky clean) -> Acus 350 powered speaker (very FRFR, no added EQ)
Sounds pretty amazing. Discovered by accident, in this chain the Joyo provides a unique EQ that's hard to replicate. It's a warm, woody, acoustic sound. With clarity but without harshness or the wrong sorts of muddy overtones. Chain sounds OK with regular archtop with an Armstrong hand wound, but comes alive with the Wu, phosphor strings, and the Sunrise pup. Don't get the same impact with a regular guitar amp.

Or are you using AX -8 essentially like a preamp thru some of your favorite Guitar Cabs ?
Your Recording set up ( and playing obviously ) really works even on Youtube- you must have heard this before - which is why I ask .
