Blown speaker, stupid move?


I’m newly configuring a system. Yesterday, I finally received the last of the pieces, preamp and cables. But without realizing it initially, UPS had damaged the preamp, such that it didn’t work. Now, I had not yet heard either speaker or amp, and I was anxious to try and troubleshoot the whole thing. So I plugged in TV out, thinking that the TV volume might have controlled gain. And the thing blared. I did it twice. About two, three seconds, each time. Although I know it’s tough to say, I’m curious for the responses: What do you think are the chances that such a move blew my tweeter or other speakers?

Thanks Matt, thanks JMc. I am comforted by the likely remote possibility. That was a great discussion at that link as well. Separately someone gave me the link for a great craftsman, should the ultimate (or future) need arise.

I found it somewhat humorous that the other post's author also liberally used the word "stupid". Ha! We're not all that different, all of us.

I won't get the opportunity to listen to them yet for perhaps another couple of weeks as I need to sort out/replace the preamp situation. And when that times comes, until I can tune my new ear with music, I see some great resources for various pink noise generators, and the like.

Thanks again! This group has been an amazing resource. And I think I've gone from kindergarten to graduate in a short number of days/weeks!

And btw, travel in both woofer and midrange seems smooth. (Tweeter way to small for me to try it.)

David, funny. Ebm, you were the one who said in the other post that "your speakers are trashed" right?
