I also am going to include more info I found on another site from david

Here are a few of the differences between the Wetsounds Rev10 and the Rev410. From here you can decide which attributes fit your particular tower and application the best. Both have advantages in different scenarios.
The Rev410 has slightly more surface area on the midbass drivers because the cones are continuous and sealed. Because of the pod shape, the pod displacement of one Rev410 is slightly larger than that of a pair of Rev10s. So as a result the Rev410 has a slight advantage in midbass extension.
The Rev410 has a comparatively huge tweeter diaphram/voice coil and motor. The Rev410 has a more developed horn architecture with no parallel surfaces. The Rev410 horn tweeter has a lower resonance and reaches deeper into the midrange. So as a result, the Rev410 has a smoother transition between the midbass drivers and the compression horn tweeter. It's really tough, if not impossible, to beat this speaker for HLCD sound quality from a purist standpoint.
The Rev10 is a bit more aggressive on the highest octave so percussion and upper harmonics may sound a bit more distinctive, not necessarily more accurate, but just a bit more accentuated. And honestly, many listeners prefer a bit more aggression at both extremes of the music spectrum. So this small difference is actually welcomed by most.
The average output of one pair of Rev10s and a single Rev410 is essentially the same. The peak output favors the Rev10. Sure, the pair of Rev10s has two tweeter/horns...while the Rev410 has one...but the 410 tweeter/horn is more substantial in every respect. It really gets back to the subtle tonal differences, and not an output difference.
A horizontal array of Rev10s with swivel collars on the outside give you the ability on some towers to fan out the array. This has two advantages. You can widen the dispersion outside the wake and also lessen the impact of off-axis comb filtering (off-axis cancellations that manifest as narrow bandwidth response peaks and valleys as you move out wide). This also keeps the sound from beaming down the middle as much. Plus, the fanned outside speakers are directed more away from the occupants at the rear of the cockpit.
This makes a pretty good case for the Wetsounds 3-Some, giving you all the 'pros' without any of the 'cons'.
Normally the 3-Some gets wired L, Bridged, Right. But, depending on the specific tower and speaker arrangement, L, R, L can work out better, or you can go Mono all the way across.
