You'll need to take a look at it, but you might be able to add a second set by using the existing (two) holes as provisions for two new pairs of posts.. i.e. you punch two holes, one each (respectively) left and right of the existing post hole pattern. In this way, the two original holes are split up to become one hole each for the new side-by-side setup.
I've never done it, but it sounds possible - at least before I look into an amp ;-)

by Ralph dampened my enthusiasm...But you guys may want experiment with your new designs and see if it is worth it. There are a lot of people who would welcome the extra set of binding post for bi-wiring or for hooking up subs. Just a passing thought. But the left right holes are a good idea....thanks

If you are simply bi-wiring, the provided Cardas posts should have sufficient throw to easily accept two lugs per terminal. If you'd like to drive powered subs with the voltage signal from the output, then the female 'twin banana jack' design of the Cardas posts might well suffice.
Since Atma-Sphere OTLs (like most OTL amplifiers) tend to prefer moderately higher impedances, they do not anticipate the need to drive *paralleled* loads at any significant power.. as they tend to be of a lower impedance.
The other side of this, is that when we see units which have been modified in the field, far too often the work is of negligible quality. And while there are certainly individuals qualified to perform this type of work, we instinctively tend to discourage it - based upon what we have encountered over the years.

The reason I even thought about the mod to start with has a lot to do with the configuration of the stuff here. I am using short 10 AWG flat silver wires, with my previous amps i was vertically bi-amping, so obviously the the low and top halves of the Soundlab'c crossovers were driven from different connectors. These wires do not have spades or connectors, i formed a U shaped cutout on the flat silver itself. So everything is on the stiff and bulky side that made connecting two wires to the same terminal quite challenging, But it is done and not going to be touched for a while. I could go back to single wire and a jumper on the speaker, or just take the backplate out and reconnect the two halves to the same terminal.
..... right now...it will stay as is.
