View Full Version : Question on CDt's power handling

03-06-2007, 01:23 AM
Just bought a pair of Cdt's CL- 61a. 110 rms per side, and I have a good amp to power them. The kicker 650.4 that pushes 120rms x 4 at 4 ohm, but it can be bridged to 325 x 2 at 4 ohm.

My question is whats the rms power handling on each tweeter and each mid?

I want to get the most output of these comps without blowing them.

they definately cant take 300watts...

well i know they cant take 300 watts....

im assuming 80 rms each tweeter and mid? which means I could get 320 rms in the front? 160 per side?

You're either going to have 120x2 with two unused channelse or 325x2. You are probably better off just running two of the channels on your amp.

Where are these numbers coming from?

well if I run only 2 of the channels, im only getting 55rms to each tweeter(2) and each mid(2), but when im trying to find out is what is the rms for each tweeter, and each mid? Or did I just answer my own question at 55rms each tweeter and each midrange?

My question is what is the rms of each mid and tweet?

I know that the CL 61's do 110rms per side, which is 55 per tweet and per mid each side...what im trying to figure out is what is the rms for each tweeter and each mid?

On other words can I bridge the amp that does 325 rms x2 at 4 ohm and set the gain to 200 per side, and run 100 watts per mid and per tweet without blowing my speakers?

I think I found my answer I was looking for located on a different forum link below:


How does that sound?

If you cross them @ 100hz the power handling goes up some too.

Edit: Nevermind, you are probably listing the ph @ 100hz.. doh :) I need to goto bed.
CDT used to have the ph rating @ around 60hz.

so what exactly does that mean? what can they handle?

Very generally, if you have a sub and are high passing the component speakers at the typical 80Hz - 100 hz, components can handle about twice what they are rated for full-range.

I looked up the CL-61 and the rating I have says 90 watts RMS from 60 - 20HZ.

So, with the high pass around 100, they should handle roughly 180 watts.

Sounds like you will have more power than you need. I would bridge the amp, maybe set the gains a little low, and just go easy on the volume control, baby it. You don't always drive with the gas pedal stuck to the floor, you can handle a volume control. :D

So each tweet and midrange can handle 90 watts rms, which is 180rms per side? So setting the gain around 200 is okay then?

If the set below is the one you have it has a 130wRMS power rating @ 100hz HP... I'm assuming the crossover is set to cross the mid @ 100hz already, but if you have a deck with hp/lp settings set it to 100hz. I'm not sure how much above that you would be able to manage but if you are careful you could play it by ear.
