With active speakers, there are less connections..
which helps reduce the chances of something failing.
And with new technology, powered speakers are smaller, and almost as light as non-powered.
Yes and no. There are pro's and con's to both. Passive speakers only need one wire to each speaker. Powered speakers require 2 wires to each speaker. One XLR from the mixer and one 110 to power them. So with powered speakers you have to run a 110 to each speaker plus an XLR. If a powered speaker goes down It's a usles box that can't be used until you fix the amp. In a passive system if the amp goes out, you can simply switch to another amp and the speaker can still be used. As for weight. a passive speaker is lighter and the newer power amps are much lighter then the older style amps of the old days. Power amps come in 2 channel or 4 channel and even 8 channel models. So one 4 channel amp can run 2 tops and 2 subs with a single amp. With the lighter power amps you can put more amps in a rack case and still lift it without a forklift. But if a powered speaker goes down you only loose that one speaker, UNLESS the DSP part of the speaker goes out and doesn't send signal to the other if you dasy chaining them in mono.
Used passive gear is much cheaper then powered systems if budget is an issue. With powered speakers you are stuck with the onboard amp that comes with the speaker. With passive speakers you can choose what ever brand and size amp you like.
With powered speakers you will need longer XLR cables and longer 110 cables to each speaker. With passive you can use short XLR cables and long speaker cables.
Many powered speakers have DSP issues and there reliability is not as good. But with with onboard DSP it will eliminate xovers needed for passive systems with tops and subs. But the down side is to make adjustments you have to do it at the back of each powered speaker. With passive you can make adjustments from one unit located in your mixer rack.
Small systems with 2 tops and one or two subs a powered system is simple but so is a passive system. With a large system, my choice is passive.
To say one is easier and or simpler is not a true statement.
Shop GC used section and compare cost of used gear. If you but quality equipment, chances of a piece of gear failing are lower with passive systems.
Search problems with powered speakers and you will fine many cases where powered speakers fail for one reason or another.
Also with powered speakers you have to turn the speaker on and off at the back of each speaker.
Like I said, there are pro's and con's with both. So choose the rite system for your needs.
Dynacord has lightweight PRO QUALITY power amps with up to 8 channels with built in DSP so one amp can run tops,subs and monitors with a single amp in a 2U unit. And they are not as expensive as you might think.
A properly set up passive rack system is actually faster to set up then a powered system is.
