So far, I thought impedance meant the same as efficiency. That is why I chose 8 ohm speakers. Not sure why someone would purchase 4 ohm speakers because wouldn't that require a more powerful amplifier? So, why then do manufacturers make 4 ohm speakers? I didn't realize Tekton manufactures some of their speakers in both 4 ohm and 8 ohm.
I think Carbon Miller has a lot of knowledge.
I wish this forum could provide Zoom seminar so we could learn more from some of those who have a lot of knowledge to share. I think just knowing the basics could save us all a lot of money to avoid making some mistakes. Perhaps, Audiogon could think about providing Zoom seminars. This would really provide those like myself who don't have the knowledge a way to gain better understanding. Otherwise, I think a lot of us still do not have the sound they are looking for. Carbon Miller would be an excellent teacher along with others in this group. Perhaps provide Zoom meetings to allow us to see one another and to have discussions.
I still wonder why some speaker manufacturers design their speakers with a 4 ohm design as opposed to 8 ohm. Vienna Acoustics comes to mind. I also wonder why some manufacture their speakers with soft dome speakers vs Beryilium. I know soft dome tweeters sound less bright. When I listened to Vienna Acoustic speakers I noticed they sound nice for classical music. However, I thought they lacked the detail such a cymbals when listening to jazz.
