I think you should try to pull the crossover out if you can. There may have been some damage to it when/if it was removed and put back in.

I agree too. To properly check the crossover.

That soldering job is just plain nasty. Looks like they added too much flux, let the solder over heat and didn't bother cleaning it off.

Also so to your tool problems semajha. Just go to Walmart and pick up a 3M soldering iron in the auto department. Probably one of the best soldering irons I have used under $25. Then pick up some allen wrenches and hex screwdrivers for cheap. If not there is always Harbor Freight. biggrin.gif

Try and see if the "broken" woofer works straight from the amp to the speaker. That way you can rule out it being the woofer.

Don't mean to break the conversation on the repair in progress, But do any of y'all have a source for the foam lifts people use under their speakers to isolate them? I also need a bigger one for a sub-woofer...

No worries man, I've been whoring this thread for quite a few pages now, haha. The most common foam I see people put underneath their speakers are from a company called, Auralex. Haven't had any experience with the stuff but everyone seems to love 'em.

http://www.auralex.com/

They make em for subwoofers too.

semajha posted a link to this thread on the Ascend Acoustics forum.

As a volunteer forum moderator for Ascend Acoustics, I can tell you that the someone modified those Sierra-1 speakers before semajha got a hold of them.

If the seller was trying to sell them as "stock", then it was seriously misrepresented.

Thank you for chiming in. I did not believe that would have been factory work, I was not trying to question Sierra's factory quality. This looks to be end-user modifications gone terribly wrong.

What is strange to me is, how could this person have made the mods to both speakers and caused the same problem on both speakers? It doesn't seem like something has been broken. I think something was blatantly done wrong, ie some connection on the crossover was soldered to the wrong location, or not connected at all.

Oh...I didn't think you were. I just wanted it to be clear in case anyone did.

I didn't realize it was both speakers. I thought it was only one.

My main concern is that the seller tried to pass them off as stock.

Sorry, you are correct. It is only one speaker that is affected. I was unable to view the video until now. This is definitely the case of botched DIY. doh.gif

The pictures that I saw were only from one speaker. I would like to see inside the other speaker that works.
