Emerald Physics history and model progression

Guessing EP stands for Emerald Physics. No idea about KC

I had EP KCIIs that I paid extra for the factory to upgrade with Clarity Cap and Wire World OCC. While really nice in a much smaller room,  they could not fill my very large room, even with 2 @ 12" SVS powered subs. I replaced them with 3.4s with XO upgrades. These are really amazing, but still need the 2 subs in my room. Now. I have a pair of 2.8s coming which in addition to the same 12" concentric drivers there are 2 @ 15" carbon fiber woofers per cabinet. Hoping they will eliminate the need for the subs.


Both the KCIIs and 3.4s come stock with crap wiring. The 3.4s wiring is inside the 2 sandwiched sections, but, the jumper wire to the external XO is easy to access and needs to be upgraded. I recommend ~ 2ft of wires per connector to get the XO off the speaker base, which vibrates like crazy. I chose WW OCC for this. THE IMPROVEMENT IS NOT SUBTLE

This line has been discontinued, and the factory blew out the remaining inventory at stupid low prices. You can find used pairs at great prices

You may be onto something with model numbering/differentiating, but I don't know.

Email Walter for the 411

As to pulling better wire. I just looked. Yes it is possible, as the 4 binding post mounting plate near the bottom has 6 screws (on the 3.4s it is a concentric driver, meaning 2 sets of wire). As to pulling new wire, it would need to be thin-ish to get both through the hole. That said, the wire from the speaker to the binding post is much thicker than the crap wire provided to jump to the XO. One could also simply run new thicker wire outside the back plate
