Powered speakers show audiophiles are confused

Great for pro audio use and in studios or for those who want simplicity in a system but most audiophiles want outboard amplification. Also many don’t want to bin a speaker setup because one amp failed inside. My experience with powered speakers failing is fairly vast and while with a few I could repair or replace amps most are junk after just 1 amp fails in a stereo pair. I have built actives but I outboard amplification because of this.

Very few statement systems have powered drivers with the exception of low frequency drivers in some cases. I can't say I ever heard a powered studio monitor that made my jaw drop, they are really made to be working loudspeakers not home playback systems. Don't confuse decent working performance with the stunning sound of large home audio loudspeakers. 

So how do you protect the amplifier inside the speaker from the rear waves off the drivers. That rear wave is equal too the wave coming from the front of the speaker? 

I've said this before... audiophiles of the type who frequent discussion boards like this are hobbyists. They like playing and experimenting with equipment.  If they buy a powered speaker, they've just given up one of the big components with which they can experiment. 

The OP's suggestion probably works much better with those who are only interested in music playback but consider the equipment end of things a necessary evil.  For them, simpler is better as long as they are getting the sound quality they like.

That made my brain hurt.
