Simple Integrity Test on Newly Delivered Speakers

[Charles Jenkinson]

I’ve just received a pair of 3012HO’s for my jack 112’s build. I have to assure that there is no damage to them within 24hrs, as a result of courier transit. Would there be a test or some simple tests that can be performed? I appreciate this is an elementary question, but I have just invested in a small corner of the global neodymium market and want to be sure everything’s ok before the transit insurance runs out. Many thanks,

Charles

I would run the break-in procedure. 10 volts @30 Hz. Any issues should be pretty clearly audible.

I agree, run them in.

Ok. Thank you gents. Frederic, your tone generator worked just fine and speakers are OK. Only I found that my HiFi amp is only working on one channel so am gonna have to get that fixed before breaking speakers in fully and moving forward. I know I need something better, but for now, it needs patching up. Thanks again.
