jperrewe Posted December 20, 2001 Share Posted December 20, 2001 Re-cabling for my new RF-3II forward speakers with 10 ga. twisted cables. Cables are bi-wired to speaker terminals, hard wired no spades. But at my reciever, it will be difficult to hard wire two 10 ga. cables to one post. I do have "A" & "B" forward speaker terminals on my receiver (8 posts in all) and don't use the "B" side currently. What would be wrong with utizing the "A" posts on the receiver for the upper speaker terminals and the "B" posts the lower speaker terminals? In addition, am I better off making direct connections or using spades and/or bananas? The Rookie needs advice! Quote Link to comment Share on other sites More sharing options...
mike stehr Posted December 20, 2001 Share Posted December 20, 2001 You mean using both A and B terminals together? It should work, all it does is convert the Reciever's amp to series. Just make sure to check the manual to see if the impedance is okay in this configuration. Should be, it's series. Surface contact area is important with wires, with spades first, banana jacks second, and then bare wire termination. This might help. THANX!

jperrewe Posted December 20, 2001 Author Share Posted December 20, 2001 Mike, Thanks for the reply. Yes, I would be using both A & B terminals togehter. Just like having four forward speakers hooked up. Could either have the upper speaker terminals (left & right channels) run to the "A" posts and the lower speaker terminals run to the "B" posts ~or~ the entire left speaker run to the 4 "A" posts and the right speaker run to the 4 "B" posts. Any comments on a preference? Santa Does Exist! Quote Link to comment Share on other sites More sharing options...
mike stehr Posted December 20, 2001 Share Posted December 20, 2001 Now you have 4 posts for 'A' left and right, and 4 posts for 'B' left and right. Right? If you hook one the speaker's upper and lower terminal's to the Reciever's 'A' left and right terminal posts, then the balance will be through the high and low end of the speaker itself, The tweeter/mid would be left, and the woofer would be right or vise versa depending on how it's wired. The same with the other side if it were configured on 'B' left and right posts. I think if you did this way, when you adjust your balance you would get tweeter/mids on the right, and woofers on the left, or a woofer on one side with a tweeter/mid on the other, again depending how it is wired. When you use A and B terminals together, its like two channel with extra posts, and the Receiver's amp will indicate what impedances allowed when configured this way. You could try it this way, Kinda throws me. I would take tweeter/mid left and right speaker terminals put them on left and right 'A' Reciever terminals, and then the woofer left and right speaker terminals to the 'B' left and right terminals on the Receiver, as you previously mentioned. So when you hit just the 'A' speaker switch, you have just mid and highs, when you hit 'B' switch you just have woofers, this way your balance works out right. Man, I hope this helps.

WMcD Posted December 20, 2001 Share Posted December 20, 2001 If I can disagree, on a small technical point. The A and B switches put the speakers in parallel, not series. Some of the wiring being contemplated might put the two woofers connected to the right channel and the the two treble units connected to the left. Not good. If I understand, the mechanical problem is that you've got 10 gauge wire and the connections at the amp are not going to take these. Splitting them between the A and B makes sense, naturally. It sounds like the amp has female bananas which are also a sort of multiway connector. There is hole in the post, or you can wrap the wire around the post, or wire to a male banana. My thought is that there is some danger of damaging the connector on the amp with the big wire, or a possible short. If I was doing this, I'd look at a way of connecting the big wire to a dual or two single banana plugs. At least this is accomplished out in the open where you can fidget with it. At worst you might ruin a some cheap plugs rather than the amp. Gil Quote Link to comment Share on other sites More sharing options...
T2K Posted December 20, 2001 Share Posted December 20, 2001 Buy stackable banana plugs and stack 'em. Keith Quote Link to comment Share on other sites More sharing options...
mike stehr Posted December 21, 2001 Share Posted December 21, 2001 Thanks for the correction Gil. I'm still a little Audio challenged. IMO, to get the best out of a biwire speaker, is to toss the passive x-over and use another amp with a active crossover. Then you can tweak between high and low with the active crossover. But I just built some passive x-overs, so what am I talking about?! THANX! Quote Link to comment Share on other sites More sharing options...
jperrewe Posted December 24, 2001 Author Share Posted December 24, 2001 Mike, Gill & Keith, Thanks for the info. Sounds like finding the right connectors is the key - I had a brain void, thats why I asked for advice - think I'll save the "B" terminals for my old forward speakers and run them on our back porch. Can anyone tell me where to find 10 ga. stackable banana plugs for my amp and 10 ga. spades for the speaker terminals?
