The M2, C2, and S2 are all two-way designs using the same 6.5" woven-fiberglass woofer and 1" aluminum-dome tweeter. And there are more similarities: all of the speakers are crossed over at about 2.2kHz; all are rated with the same sensitivity, 90dB for 2.83V input under anechoic conditions; and all are also said to have the same nominal impedance of 4 ohms. Barton more than likely did all of this to give each speaker the same "sonic flavor," which is precisely what you want in a multi-speaker array thats intended to be a complete system.
However, there is one difference among the speakers: the M2 and C2 are vented designs, while the S2 is a sealed enclosure, which is not uncommon with surround speakers because they have different placement requirements than the other speakers. Front and center speakers are generally placed well away from the walls, while surround speakers are more than likely going to be butted up against the wall, or perhaps even attached right to it.
The S2 also has something interesting about it that I quite liked. PSB calls it Tri-Mode Surround. Basically, the S2 can be used in three different ways, configurable through the binding posts on the back and with special supplied jumpers. The S2 has three sides with, of course, one side thats always intended to face the wall. The other two sides, though, each have a tweeter-woofer driver array. That means each S2 speaker has four drivers in total (two tweeters, two woofers). Depending on how you connect the back binding posts and which jumpers you use, you can configure the S2 as a bipolar design, where each S2 acts as one speaker and both driver sides operate in phase; a dipole design, where each S2 still acts as one speaker, but both driver sides operate out of phase, which tends to make a more spacious rear soundfield in comparison to configuring as a bipole; or, finally, as two different speakers altogether, where each "side" is fed a different signal from the amplifier. In the latter case, you can turn your home-theater system from a five-channel system into a seven-channel system without adding any extra speakers. This will be particularly attractive for those people who want seven channels but who dont want the added expense, or to consume the extra space, that two more speakers would require. The S2 is a clever design.
