I'm not familiar with the units to which you refer but I can tell you that the pro audio world has different kinds of speakers for different applications. There are PA or sound reinforcement speakers, instrument speakers, recording monitors. Each are designed with different goals in mind.
Generally, if you choose recording monitors you will get the equivalent of a home bookshelf speaker but with a less attractive enclosure. You can couple these with a subwoofer and get sound that competes with most things in the home audio field.
Most PA speakers are designed to play loud and handle a lot of power. They can be simple for things like amplifying a sermon in a church or sophisticated like those in the theater. The good ones with fairly flat frequency response are pricey ($3000 to $4000) apiece. The simple ones can be pretty cheap (less 10% of those numbers.) Generally, unless you spend a good deal of money, these speakers won't compete sonically with consumer speakers. The good ones, however, are very good indeed. Obviously they sound like what you hear at the theater.
Instrument speakers usually have limited frequency response designed to limit their output to the frequency range of the instrument in question. You want to stay away from these.
I have experience with all of these. My first stereo speakers (yes I once upgraded from mono to stereo,) were theater speakers that I bought back in the 1960's. They were made by Altec Lansing and were called (fittingly enough) Voice of the Theater and arrived with flat black painted enclosures. I later added walnut veneer and grille cloth to them.
At the moment I use Tannoy near field recording monitors for the surround speakers in my home theater. They do a wonderful job in that application. I use JBL recording monitors in my project recording studio for mastering. They don't sound quite as nice as the Tannoys but they don't need to.
My electronic keyboards have instrument speakers designed to cover just the frequencies needed for the keyboards. They have brands like Roland and Alesis - brands you wouldn't see in the home entertainment business. To make a long story short, pro audio speakers can work wonders in a home theater if you choose them properly. They can do a very poor job if you don't.
