Need Adcom GFA-565se info
On page 9 of the user manual:All loudspeaker systems having a nominal impedance down to 2 ohms can be connected to, and driven by, the GFA-565SE. The GFA-565SE can drive these low impedances at more than adequate power levels with no difficulty. l... 
Can This Amp Power A 50 Foot Speaker Cable Run?
I ’m with zavato, the cable should be ok, most important thing to consider is the amp has enough power for such a big theater room without clipping and destroy the speakers! http://myhometheater.homestead.com/splcalculator.html

Tim, my guess is a combination of difference of ESR and those old electrolytic caps dried out and out of specs, so a tester that can check the value of the caps and ESR will give us the answer.One thing that surprised me was the cables made such...

Btw, all cap in the crossover should be bipolar/non-polarized, therefore the two 2200uf connected back to back.

Yes, C1,3 and 4 must use bipolar cap

The two 2200uF polarized electrolytic back to back in series to form a non-polarize cap.

I think what Ill do is buy a tester that can check the value of the caps as well as check the ESR and see what pops out at me. Totally agree, and this link is worth a read:http://www.diyaudio.com/forums/multi-way/282847-original-electrolytic-ca...

The caps I replaced were: the electrolytic, (2- 6.8uF , 2- 8uF, a 47uf and a 10uF) Also film caps, 3- 3.3uF, 2 -10uF and a 4.7uF.Two polarized electrolytic 2200uF, but these I replaced with electrolytics. C8=4X3.3uF=13.2uF and you replaced it wi...

If caps are parallel, measure it in circuit.

Just read the caps itself, you can compare the new caps with the existing caps which you took out from the crossover board.

How can I tell what the resistance should be, that device that Tim posted , will that tell me the correct resistance? If I measure the other crossover that I haven't changed any electrolytic caps out of yet. If I find out the correct resistanc...

With using just plain old zip cord I get better highs than the temporal continuums. Anyone have any idea why? What setting on the dials? on the highest?

I did replace two of three of the mid-range caps, as well as three of the five tweeter caps. Can you let us know which caps you replaced? the value of the caps ( ie: 2.2uF 100V)?
