Synergistic New Tesla Line...Any comments?

Fplanner2010, I think I understand what you are attempting to do and don't understand why you are doing it. I think you have two sets of Apex speaker wires running from your amp to each Universal Speaker Cells and one set of pigtails from the Cells to your speakers and that previously you had one set of your Apex speaker wires connected directly to your speakers bypassing the Universal Cells. Forgive me if I misunderstand, but I would simply get another set of pigtails to run between the Cells and the speakers and remove the second set of Apex cables. Or get another set of Universal cells. This would be expensive and I suspect overkill.

Tbg - You almost confused me!!
Let me explain a bit more clearly. Before speaker cells: Apex biwires hooked to my VR-7s in bass and mid modules; 1 amp per side. Currently: 1 speaker just as before. 2nd speaker with both Apex main and Apex pigtails (hence "biwire") hooked to speaker cell input terminals; 48" leads(2) from speaker cell hooked to midrange terminals on speaker, 16" leads(2) from speaker cell hooked to bass terminals of the speaker. What we hadn't done before was to hook the Apex pigtails to the speaker cell input terminals as well, but just left them un-connected.

BTW, shortening the bass leads from the speaker cell from 48" to 16" noticeably tightened up the bass, which I was happy to hear. After a few more days of "A-B"-ing the 2 speakers, I will hook the other speaker cell up and hopefully be happy with the result. So far, I am getting better instrument separation and a bit more detail out of the speaker hooked to the speaker cell. The bass is also a bit deeper and tighter than the non-speaker cell speaker.

What is difficult to ascertain until I hook the other speaker to the speaker cell is their effect on the overall musicality of the system. It was pretty non-existent before when the cables weren't hooked up properly. I'm expecting a huge positive difference now, hopefully even better than without the cells at all. If that happens, I will of course keep the cells. The next week or so should be pretty interesting.

Fplanner2010, now I am more confused. What does "both Apex main and Apex pigtails hooked to speaker cell input" mean? I know there are pigtails on the ends of Apex speaker cables. Presumably these are not what you mean. I know that the Universal Speaker Cells come with Basik speaker wires. Is that what you mean by Apex pig tails? If this is so, who suggest that you do this? I would not expect that have fully shielded Apex speaker wires with unshielded Basiks would be best.

If none of this is the case, just ignore me.

Tbg - Its VERY SIMPLE - My Apex cables are BI-WIRE, which means there are 4 ends that go to the speakers. 2 of those ends are heavier(main) and the other 2 come off of the main Apex cable as 48" pigtails. All are spade terminated, with the main ends being heavier spades than those at the ends of the pigtails. Hooking ALL 4 up to the INPUT side of the speaker cell solved my problem. If this is still confusing, SR can perhaps explains better than I.
Thanks for your feedback.

Fplanner2010, I now understand. I can only imagine what it must be like dealing with the Apex speaker wires at the Universal Speaker Cells. When I connected my single run of Apex speaker wires, they wanted to twist the Universal cells onto their sides. I just put a lead weight on overnight and let gravity twist the Apex into level.
