I use the PAS system as a PA with my console. 4 units are either paired on left and right (2 on each side) for front with a digital console, or 2 front, 2 monitor. Either way they work great for small to medium small venues.

I do find I need more power in front. That's when I pair two on each side.

What about designing a base (may be a split base) with two towers right next to each other? This would provide for no phase differences on one side. And with enough power to handle 4 bass units on each side. The speakers are already made, the new item would be the base, which would contain only one input to receive signal from the console, or maybe two, just in case there is a musician that wants to use it as a PAS. You could call it the PASPA and it would surely blend into the medium size array systems for medium size venues.

Hi, Pedro:

That's an interesting idea ... but then you wouldn't be able to use them as

2 front, 2 monitor.

Not to mention that you'd have to rename the unit the L2.

Actually, from a technical standpoint, there's a good reason why a product like the one you've described hasn't been developed. The L1 loudspeaker is a line radiator which continues to radiate cylindrically even at high frequencies. When you place two high-frequency sources side-by-side, they begin to interfere with each other, producing very narrow horizontal dispersion at high frequencies. This is because as you move farther off axis, the difference in the distances between you and each audio source increases (that is, you are farther away from one L1 than the other). When the difference in distance between you and each L1 is equal to or greater than a multiple of 1/2 the wavelength of the frequency being produced, the waves interfere destructively. If you start from one extreme angle and walk across the coverage field, you'll notice that some areas receive a more 'airy' sound than others, due to the fact that comb filtering causes the other areas to be acoustically shadowed. Placing two L1 loudspeakers side-by-side to achieve additional loudness isn't a good idea, because you're sacrificing even coverage and consistent sound quality.

If an L1 loudspeaker and four B1 bass modules isn't giving you the amount of sound you want, then it's time to consider stepping up to Bose 802s, or perhaps a larger multiway speaker from the Bose Panaray LT range, or from another manufacturer, like Community. If you need silly output levels from a small loudspeaker, consider the Community SLS920, which can achieve peak levels of 137dB (measured at the standard 1m distance) with only a 500w power amplifier.
