Feature:
It is lighter weight because of the neodymium magnets and the lighter, cheaper class-D amp.

Quality:
As far as class D amp go, this is one of the cleverest designs so far. It compensates very well for the gimmicky limitations of the cheaper Class-D topology.

Value:
The older models are a better value. Neodymium SHOULD cost LESS, NOT MORE. And class D amplifiers are cheaper, not better.

Desirability:
The "I want it" factor depends on how misinformed you are. If you mistakenly believe that neodymium is rare or expensive because it is called a "rare earth" element, then you might be fooled. Also, new "class-D" amplifiers are less expensive to make. Why then, should this new model cost MORE than the older one?

Sound:
Basically, just as good as the previous model.

Ease of Use:
Easy, fast, good.

Support:
Honestly, have you ever tried to get a response from Mackie?

Overall:
I'm certain that this speaker sounds good, just like the old one. I know it weighs a little less. ( 6lbs ) That isn't worth an extra 20%

Feature:
Mike/Line input switch is nice.

Quality:
Sorry, Mackie. Your reputation for quality products is really suffering these days.

Value:
If it's distorted out of the box, there's no value.

Sound:
I borrowed these speakers while PA was in the shop. In the past I owned mackie SRM450s - the first edition. The 350 v2's are buzzy and distorted even at low volumes. I adjusted inputs, outputs, etc, etc. Wondered if my mixer was at fault (a Mackie Onyx 1620) so listened via headphones. Nope. I couldn't recommend these speakers for any use. Also, my friend who loaned them to me told me these were replacements for the first pair.

Ease of Use:
How hard can it be?

Support:
Not used.
