Hello everyone. Im new to this site so if this is the wrong section then I want to apologize. But I had a question about adding some speakers to an existing theater setup. My husbands birthday is coming up and Id love to buy him a pair of speakers that I can get a good deal on. Im not too familiar with audio setups but I know he bought a onkyo home theater in a box thingy a couple years ago for our media room. He's always been talking about upgrading the speakers because the ones that came with the system were ok. But anways, I found a good deal on some front speakers made by definite technology called BP6. I read reviews and they seem like good speakers but I dont know if its ok to add them to his current system. Would that be ok? Im sure they will work but I want to make sure they will be better then the ones he has now. Will be a big noticeable difference or will it be hard to tell? The receiver hes using is a Onkyo HT-RC160 if that helps with anything. I just want to buy him these and let him start upgrading his system so we can watch some movies! Any help would be greatly appreciated. Thanks!
