as a person that is an audiophile but also as a musician that has run sound for bands over the years and also have set up club sound systems in the past I do have some knowledge on this subject. The JBL's are good pro sound speakers and they will serve you well as long as you set the rest of the system up to power them well and have a good clean front end. Another couple of brands that I have worked with over the years that are good and have models at about every budget and power handling are Yamaha and EV, while they have affordable models they also have models that have tremendous power handling and some of the best drivers for their said price range. There are higher end pro sound brands out there but I really don't know what your budget is and these brands are way more expensive than the JBl or the other brands mentioned. The main thing is to find someone that has knowledge on the setup of these speakers so that you make sure that you get the right amount of power for them as well as making sure they are crossed over right if you are going to be running separate subwoofers with the main speakers which I would recommend for that size of area if you want a full range sound without the bottom end being to small sounding.
