Feature:
The eq is a plus , and you dont have to put the gain all the way. You can leave it half way and still jam. The mackie only has the kill to the lows. Comparing both your talking 2 different styles but both are in the top of the food chain, Now if you talk JBL and Peavey then they need some work.

Quality:
top of the line,

Value:
There a bit pricey but like they say you get what you pay for. Its a high quality speaker so when your doing an event you dont have to worry about amps heating up or distortion.

Desirability:
its a different look from other manufacturers, its well desing and sleek as well as you can position it in any angle.

Sound:
I have had a pair of these speakers for the past 3 years, havent had the issues others have had, the mids and highs are clear compared to the Mackies that I also own. At the same time they kick some low's compared that the Mackie sounds like if its pounding a clap. I also added the powered 18's to my Ev's and i can do a gig up to 500 and still be jamming. The mackies are more for small gigs.

Ease of Use:
Just plug and play plus they speakers half both a 1/4 and xlr plus a added microphone connection, compared to the other competitors they have no room

Support:
havent had an issue to call customer support till this day. Plus the warranty is for 6 years.

Overall:
I will continue to use these speakers, i owned previously a pair of powered QSC's and the next day i exchanged them. QSC makes good amps but not the cabinets

Feature:
Very simple, clean. Has HF and LF EQ. I leave the EQ flat, and adjust if needed on my mixer. Anything more is pointless in a way, because it would require more circuits. Think of it as having two volume controls, one for each amp, HF and LF. I have not tested the limiter at all, as this is very loud on half volume.

Quality:
Clean, solid, heavy wood with a resistant finish and steel handles and pole mounts. Gets hot, but that is to be expected with a 600W speaker.

Value:
Look around for the lowest deal at an authorized dealer and then price match. Good deal, considering this is the stuff the pros use.

Desirability:
This has a very professional look. Black case. Steel Grill. No frills, lights, or other bojangles. When it is off, it is discreet. Turn it on and the people will flock. Very, very human, present tone. If you are going to win people through their ears, buy this. If you want to mesmerize the easily distracted with flashing lights, look elsewhere, though this may convince a few of that type to listen as well.

Sound:
Hard to Describe...Best term would be...well-melded, like a grilled cheese sandwich where the cheese is melted, but not running, falling-out or lava-hot, and the bread is crispy, not burnt. Compared these to Mackie 450v2, QSC 15" version, JBL EON... Mackie is too crisp, with distinct separation between the lows and the highs (burnt bread). QSC is good, but while it seems loud and has a much more even response than the Mackies, it lacked the clarity in the mid-range that the EVs have. The EONs are muddy and booming, good for hip-hop if that. Check these out, preferably with some singing. The 15" woofer allows enough bass.

Ease of Use:
Turn it on. Leave EQ flat. Turn Volume Halfway. Play music.

Support:
Excellent online resources, could reach a person easily on the phone. No problems so far.

Overall:
I may get the sub woofer later, but for my uses as a DJ playing parties of 100-500 people in 10,000sq ft to 90000sq ft spaces, this is great. These are a long-term investment, and should hold their resale value. The company has been around for a long time, and overall, is owned by Bosch which I don't think is going anywhere.

Feature:
There are not many features on the SXA 250 just kinda bog standard. A volume knob a basic Eq in's and out's and thats about it.

Quality:
I have had the SXA'a for 3 years now and have had them break down on me 3 times.I earn my living by giging and over the years have owned a number of Pa speakers and for reliability the SXA 250's have been by far the worst. So this last time of breaking down was for me the plump for the Mackie SRM 450's.

Value:
Considering you could almost buy 2 Mackie SRM450's for the price 1 SXA 250 I dont think they are good value

Desirability:
It has NO sex appeal at all - No sexy lights or curvy styling just a Black box

Sound:
I bought two of these EV powered speakers thinking I was buying a Roll's Royce product but found this not to be the case, although it certainly has a Roll's Royce price tag. The sound overall was fairly good apart from very dissapointing lows which is really unusual for a 15" speaker. I have recently tried the Mackie SRM450's and I have found they have far better lows and are a lot louder. I've found that the SXA's really dont like to be driven hard and tend to break up when cranked.Bear in mind I am a solo singer / acoustic guitarist playing to backing tracks in smallish venues so I dont get that loud!! When I emailed EV about this they told me to buy a sub!!!

Ease of Use:
Very Simple to use

Support:
I live in London and I have dealt on a few occasions with the British service dept. They were ok but even when one of the speakers broke down within warranty the company would not loan me a speaker to cover gigs I had booked while the broken speaker was being repaired. So I had to hire a pair of Pa speakers for two weeks!!

Overall:
I think for the price this speaker is vastly overated. Dont get me wrong I may just have been unlucky with the breakdowns and someone else could have them for years without a problem, but I can only soeak as I find and anyway there's still the lack of bass end and the big lack of power.
