I just recieved a used Rainbow SLC 265.03 component set and I have a couple questions...

1. I will be powering them with a Xtant A4004 4-channel amplifier, that outputs 50W RMS x 4 @ 4 ohms or 200W x 2 @ 4 ohms bridged. I think these speakers are rated for 60 or 65W nominal. I think it's 100W max. The crossover for the speakers allows for bi-amping. I'm only going to use this amplifier for powering the front speakers, so should I:

a. Run 200W RMS to each side.

b. Bi-amp and run 50W to the tweeters and 50W to the mids

c. Just use 2 channels on the amp and run 50W to each side

2. I need an explanation of this crossover. I don't have a picture but here's a diagram of what it looks like:

From the output side first, I'm guessing the -3db is for the tweeter level, but how do I use that?

Now onto the input side, what is the connection with the "T"?

How would I connect the amplifier to the input side if I'm bi-amping?

Thanks in advance!

I made an error, the speakers are rated for 80W RMS @ 4 ohms and 100W max.

If you have the power and channels to spare, I would go the bi-amp route. More control and volume.

As far as input, match what it says on the crossover. Tw=tweeter, you have one input for negative and one input for the positive. W=obviously goes to the woofer, and again two inputs for neg. and pos.

As far as using the tweeter attenuation, I'd would strongly urge you to try both settings, but I have a strong suspicion that you will wind up using the -3dB setting. Connect the neg. lead from the tweeter to the - symbol on the output and then you can either choose the flat position on the x-over or choose the -3dB position with the positive lead.

A trick that was taught to me about with these x-over's (by the rainbow rep) was to open them up, and inside there is small tan tab with two metal leads going into the board of the x-over. Take a pair of needle nose pliers and twist this so the two metal posts touch, you disable the tweeter protection, which enables a little more power through to them. THIS IS JUST A SUGGESTION, NOT A NECESSITY.

Nice speakers by the way.

Alright thanks for the reply. I'm going to try to run them off of just 50W just to see how they are, because I might end up using some rear channel speakers and running those off of the amp. I heard that these speakers have a pretty high sensitivity so they don't need that much power.
