But a 12” woofer would need *massive* EQ to play any treble….

Part of their “marketing.” Intimidation of competition. The MA FRM 3ax is a great sounding little bookshelf speaker.
Considering there are eighteen of them…
A 12" guitar speaker has no trouble handling treble up to around 5K but than it doesn't do well below 80hz either.

There are some great 4” drivers out there today. I wonder how they’d do in place of the Bose drivers in the 901….
Best speakers Bose ever made, IMCO.

The 601 Series 2 was a good sounding speaker. I came very close to buying a pair, back in the day.
Because it's not a woofer, it's a full range driver.
Why risk wrecking 9 "great" drivers to try to improve a very compromised design? I'd just let sleeping dogs lie.
Full range as far as guitars go.

Because we know Bose used cheap drivers. A “compromised” design because they used cheap drivers. How else do you think they could afford such a huge marketing campaign?
There’s a plethora of modern speaker designs out now using multiple small not-cheap drivers. By your theory, they’re all “compromised” and should be shunned, as a sleeping dog.

But that was not my point. I was only comparing the surface areas of one 12" woofer to multiple 4" units and their respective bass capabilities.

Not your point? What then, was your point?
You forgot to add the tuned ports to that broad brush stroke. As I said above, there are now a plethora of modern high-end speakers that use multiple smaller drivers to achieve greater surface area and composite low bass response. Hardly a “sleeping dog” concept.

I never diverted from the Bose subject. You did.
Well, let’s get back to apples vs apples.
The 9 x 4” drivers (901) (2 ohms each) are equivalent to an 11” woofer in surface area, with the ability to play midrange and treble. Also, ported. One 12” woofer won’t do treble. At all. My old (1965) AR-2ax has a 10” woofer (each), and fills my 20’ x 30’ room with bass. But it rolls off at 1400 Hz.

Huh? Those drivers were designed for a specific purpose. Find me a line array with an active EQ and you may have an argument. These were designed for that purpose. The "compromises" in the 901 design are many. Tweeters would be nice, but aren't compatible with the active EQ. The highly resonant blow molded plastic enclosure is a major compromise. I could continue, but it would be just piling on. You don't have any point here that I can see, other than making a strawman argument.
BTW, yes Bose used cheap drivers in most applications, can't argue that point either. They used cheap enclosures. They typically used rudimentary crossovers, the exceptions typically being were a better crossover allowed for cheaper drivers. A cap and a lightbulb worked for them a long time.

Huh??
Obviously you didn’t read what I wrote. Most line arrays have a woofer, midranges and tweeters…. So apples and oranges, not worth bringing up. But you did… to make what point? The 901s aren’t line arrays. You didn’t know that?
Of course, the EQ was to push the small drivers at their frequency extremes. Have to! Each one is used as a full-range driver! So no revelations there, either…
What else?
Oh, yeah…
Whatever your supposed point, my point was that it is very common to use multiple small woofers to act in unison as one larger bass driver. It allows the building of tower configurations with narrow front exposures, where 12/15/18” are just too broad. Some use PRs on the broader side real estate. Some use internal woofers to assist or tune the front-mounted drivers.
I already stated that Bose used cheap drivers, so why are you using that to assist in making “your” point? Strawman argument, maybe?
As for cabinet construction, there’s also a plethora of those out there, even in modern offerings. CNC routers makes it doubly cheap these days.
And you aren't going to see it.

And that has exactly *what* to do with cabinet construction, cheap vs not? Unless it’s open baffle, you don’t see any cabinet construction on speakers. So your point is moot.
