CDT 3-way Crossover Question
I have CDT CL 641 3-way component system. Is it possible to change the crossover unit from the one that came with it to the ES-300 crossover (one for eurosports)? If so would there be any benefit to doing this?
Thanks
Thanks

Although they are CDT's entry level components, the CL series is still much better than many other component sets out there in the same price range. The crossover for the CL-641s are made for that component set and I would suggest sticking with that one as the crossover points might be different on the other crossover and like stated above...could do more harm than good.

Thanks for your responses. I talked with CDT this morning and they said that it would improve my sound quality and imaging and that wouldn't hurt my speakers as long as I don't provide more power than they are rated for. Zeb has a sell on them for like $84 bucks so what the hell I am going to test them out.

I thought that at first, but the 3-way eurosports and the 3-way CL line both have the same frequency response 55 - 20khz. And they are both 4 ohms. Only sense I can make out of it is the Euros are better at reproducing those frequencies than the CL line, and they handle more power, has a better voice coil, etc. that is why there is a price difference

If the Eurosports indeed handle more power- by this I'm assuming the crossover therefore has larger capacitors/ inductors/ resistors- this could cause a
'resistance load' from the speaker back to the crossover/amp since the Eurosports (even though they play the same frequencies) do so with a lot more power

My mistake the new crossover will allow more power handling for the CL. Here is what CDT told me.
Yes you can and power handling will increase and sound more clean and clear
and detailed

I got the crossovers and installed them over the weekend and I must say that it improved the detail of sound, imaging, clarity, and bass response. The only thing now is when I rehooked everything back up I introduced an alt whine in my system. I had it before with my old crossovers before I regrounded everything, but it's back.

why is greater power handling of the higher quality crossover so hard to believe? if the caps used in the lower end crossover aren't rated for use in higher power situations then the lower end crossover would handle less power. also same goes with the inductors. if the lower end crossover uses inductors wound with 18awg, they will handle less power than a higher end crossover that uses 16, 14, or even 12awg wound inductors. i don't see what is so hard to believe about this.

Also what if the crossover was properly built in the first point and that it is the tweeter that blows. Power handling can then be improved by increasing the slope of the high pass section.

You say "change the caps and coils" which might work, but there could be a 5W resistor used where a 10W is required. Do you see my point. A circuit is only as good as it's weakest part. You are probably right that it is the caps and coils, but you could also be wrong.
