I purchased these Es 15's for my rear channel home theater setup couldn't be happier for the excellent sound. First time I've had any Polk speakers, I have a medium size bedroom and they are more than enough, Hi res Tweeters are excellent!! After a little tweaking of my EQ the bass is pretty impressive also. I have them mounted on the wall so I'm sure the bass response is being muffled a bit but still yet they sound great considering they are on the smaller side with only 5.25 inch woofers. I have the Polk monitor 40's as my front and a Klipsch rp250c for my center channel, I'm saving now to upgrade my subwoofer and I'm pretty sure I'm going to get the SVS pb-1000. If anyone has a better suggestion please let me know but they seem hard to beat and I love that they have an app to control all the settings for the sub, I'm a paraplegic so that works perfect for me because even when in my wheelchair it's hard to get down and reach the controls on the back of a sub to tune it. Thanks for any suggestions
