Any equipment and installations with input and/or output voltages greater than 50VAC RMS and/or 75VDC are considered hazardous. If you're running an amp that can provide around 600W into a 4 Ohm load or 300W into an 8 Ohm load, you're working with hazardous voltages.

hmmmm ... think axiom needs to make protective covers for the back of their speakers.

If you connect via stripped wire, fork or ring tongues, the banana plugs are bare on the top. You can stick two fingers in them. If you connect via banana jacks, the termination becomes safer.

I recall the banana plugs from previous versions shipped with plastic inserts that would prevent probing fingers. Of course those inserts can always be popped off quite easily.

Banana jacks are safer but not completely safe. Someone can come along, pull them out and contact them. A locking banana may be the answer (see link).

At those high wattage numbers, I think your ears would be bleeding before you could even come close to touching any wires.

bman, it depends on how far the MLP is, the sensitivity of the speakers, the room properties and the source material.

rrlev, with regard to the plastic inserts, I am referring to the terminals on the speakers. On the top of those terminals, there are holes that are exposed if you're not using banana jacks. My v2 had plastic caps that closed those holes.

I agree with both bman and you. I do not think I’d ever listen at that level continuously but dynamics could conceivably hit shockingly high voltages at fairly reasonable levels. Gives new meaning to a heart stopping passage ... although I think you would have to be holding both leads to get the full effect.

I suppose if one is worried about shock then insulated spade connectors make the most sense. Or perhaps insulated banana plugs if they can be secured well..

Dynamics...yes! If you only hold one lead, nothing will happen.
