Do you want passive monitors (cheaper, but require an amp to power them) or active monitors (more expensive, but have a built-in amp and don't need an external one)?
I am sorry, but I need to clarify and correct this description.
The difference between "passive" and "active" technically is the type of crossover that is used for the speaker.
A "passive" crossover takes the same audio feed from an amplifier and filters the frequecies and distributes them to the proper speaker.
A "active" crossover takes the same audio feed from a line level device (such as the output from your mixer or soundcard), electronically filters the frequencies, and distibutes them at line level to power amplifiers that are dedicated to each speaker.
The reason that this needs to be clarified is because there is another type of studio monitor configuration that is available, which is passive monitors with built in power amps.
Event 20/20's came as:
1 - Passive, no power amp.
2 - Passive, with power amp.
3 - Active, with power amp(s) (yes, they technicall need two different power amps...blah blah blah...)
Myself, I like the sound of passive crossovers MUCH better than active crossovers. I feel that it provides a smoother, more ear friendly sound. To that end, I prefer passive studio monitors.
Whether to get passive monitors "powered" or not (with built in amplifier, or not) is a personal decision.
I like that if my power amp messes up, I still have my monitors available to me. With powered monitors, if the amp goes, you are out of monitors until you get the amp fixed. For me, I can't afford that happening.
Next is the relative quality of amplification. I see way too many power monitors with anemic power amps! We are talking like 75 watts for woofers and 15 watts for tweeters. What I don't like about this is that often the woofer is at least rated for double that power capability, and I like HEADROOM on my speaker systems.
I run a Hafler P3000, which is some obscene amount of power at 4 ohms. Something like 200 watts a side. This ASSURES that I have plenty of "headroom" in my monitoring system. Headroom is important for when you might have unexpected surges in the audio level. If you have to push your power amp fairly hard to just get a acceptable listening level, if there is a big surge in the audio volume from the source, it will clip your power amp and cause it to output dangerously high wattage to your speakers. If your power amp is already running at a low volume to achieve the same listening volume as a lower wattage amp, you would be far less concerned with this, because the audio surge would not clip the input of your amplifier.
You can score Event 20/20 passives for about $300 new right now (a KILLER price considering I paid $360 for mine about 8 years ago!), and pick up a Hafler TA 1600 for about $150. The TA 1600 is a bit anemic in power though, only 75 watts per channel at 4 ohms (the Event 20/20's are a 4 ohm load).
You can probably score a 200-300 watt per side power amp used quite easily for around that same price. QSC and Crown are both popular and very dependable power amp companies. There are many others that could work well too.
To wrap up, in my opinion, having compared Event 20/20 passives to their active counterpart, and having compared many speaker systems between their built in passive crossovers and active crossovers on the same box, passive seems to have a more natural and smooth sound.
Having a seperate power amp means that if you ever have a problem with the amp, you can at least temporarily switch the amp and still use your monitors.
If you play in a band, and have a small stereo PA system, you could possibly just use the amp you use to power your speakers, and then you only need to shell out the $300 for the passive monitors.
A little aside about the different Event products. I don't recall ever hearing about passive 20/20's having any problems. Speakers blowing out, etc... I have heard a few complaints about the TR series stuff, where the speakers blew out fairly easily. That is something to think about. Remember that the 20/20 is their flagship monitor, and all the other stuff is cheaper knockoffs.
You are going to get a LOT of opinions on what people "think" is the 'best" monitor to buy. Basically, it is a lot of opinions! I have seen just about every reputable company represented with users that have produced quite good results using their monitors. So, aside from QC issues, it is mostly a matter is getting used to a certain monitor, rather than what is the "best".
My $300 Event's have served me very well for 8 years now. I have ABUSED these monitors (have had several times where I routed things wrong in the studio and sent hellacious blasts of white noise and feedback thru the monitors!). They haven't needed any repair. They also sound very good. They supply a decent amount of low end (but of course nothing like a power sub woofer would!), and they are pleasing to the ears.
Here is a sampling of my work I have done over the last 8 years using these monitors.
http://www.phoenixlightandsound.com/Audio . While these mp3's probably show more of the skills I possess, they DO show that you can do very nice sounding work on these monitors.
But in all fairness, once you get used to ANY monitor, you should be able to do nice work on them.
Good luck.
