Do we still need large woofers for a full sound?

Physics certainly has its unavoidable rules.
To have powerful bass, you need to move a large amount of air.
Using generously sized woofers has always been the easiest way.
We do this by using a number of small woofers.

Obviously, it is not by let singing a hundred sopranos together that you can produce the notes of a baritone, or a bass.
By leveraging our technology, we are able to get very deep notes, from our arrays of small woofers.

This solution offers several advantages, compared to large woofers.
For example, we have a very high transient response:
the sound is fast, of very high impact, articulate and from the ability to follow the musical signal very faithfully.
The use of large woofers, on the other hand, forces the use of multiple ways.
The Machs work from the extreme low end to well above 5,000Hz with the same driver, unfiltered, unequalized.
The tweeter is actually a super-tweeter that helps to refine the very high frequencies.

To give another example, in the latest ones, the Mach8XL, we use 8 16cm wideband, the compression tweeter is cut at 6dB/Octave at 7,000Hz.
Basically, in series with the tweeter, a single capacitor provides the supertweeter cut-off.

I intend to make it clear that when I say I am not using crossovers and in reality I am using a filter on the tweeter, I am not contradicting myself at all:
a crossover consists of AT LEAST two filters. In the case of a two-way crossover, a low-pass filter and a high-pass filter.
A single filter is not a crossover!
