REVs VS RSDs

A minimum of 150RMS? Are you crazy? I would say that is nearing their upper limit!
75RMS is plenty for those. Will more power help them out? Sure it will. But their MINIMUM is weeeeeeeell below 150.....somewhere around 50RMS

nope i am not crazy. i have 200 on each mid and 100 on each tweeter from a DD S4, and i still see the clip light blink every so often.

this is the reason why its good and ok to run such "crazy" amounts of power:

Music is not constant in its peak amplitude. The ratio of average power to peak power is in the order of 10-20dB. (10dB = 10 times power and 20dB = 100 times power). I would imagine that modern rock and roll/rap music the value is closer to 10dB. This means that with typical music the average power when using a 200w/ch amplifier is in the order of 20 watts per channel with the peaks rising to 200 watts. Anything higher than the 20 watt average will most certainly push the amplifier into clipping. With this scenario the tweeter in a typical bi-amplified system or one with passive crossovers will receive about 10-15% of the power. So the tweeter’s power is about 20-35 watts with our 200 watt amplifier. This is a lot of power for any single tweeter. But let us assume it is OK with this.

When the amplifier clips the energy into the tweeter is many times greater than with unclipped signals. (Of course the amount depends on the degree of clipping but it has been found that people will listen up to 10dB of clipping ). When this happens the compressed wave (now very close to a square wave) is absorbed by the tweeter (and do not forget about all the harmonics) and at this stage the tweeter goes to “the pie in the sky”.

Silly question...but here goes. Are you running the speakers and tweets off a 2 or 4 channel amp? What are the ratings?

TC is running his RSDs active, meaning each speaker requires 1 channel. 2 mids and 2 tweets, so 4 channels.

As far was power, I think he's giving his mids 200W and his tweets 100W each. Remember, the power has to be clean.

May I ask what amp just to get an idea of output and ratings. In my case I wouldn't be active. Is it better to get 2 or 4

Clean?

If you're not planing to run active, there's really no need for a 4 ch. amp, unless you can find a cheap one so you can bridge it.

yea man, you gotta keep that shit spit shined. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Clean?

Just because a Pyle amp says it does 100Wx4 doesn't really mean it will. Get an amp from a reputable company. Then read the sticky to find out how to set your gains right on the amp.

Thinking about a sundown 1004? Heard good things about them
