Barefaced Super 12T -- non-functioning T..?

[Rich]

Hi all

I've noticed that my Super 12T isn't giving the bright snap at the top end that I'd expect from a cab with a tweeter -- the specs say the usable freq range tops out at 22kHz, but I don't think it's anywhere near that. My old 1x12 practice combo's top end used to sound similar until I added a crossover and bullet tweeter, and now it's got a far more noticeable snap than the S12T. For this reason, I'm starting to wonder if the S12T's tweeter is working. Anyone know the specs of the tweeters they use? I guess it could also be the x-over, but I think the tweeter could be the place to start.

It looks like an Eminence APT-80 bullet tweeter from the pictures I've seen. Before buying a replacement, I'd check the internal wiring. You might be able to get to the crossover by unscrewing the rear input panel. I suspect it's fixed to the back of the panel. Look for charred or dislodged components and broken leads. The most likely cause - and this is pure guesswork - is the L-pad (the tweeter volume control). Check the rotary movement of the L-pad. If it's stiff and scrapes, it's likely to be faulty.

 

If you haven't got one already, buy yourself a cheap Chinese multimeter from B&Q or The Range. You can use it to test continuity between connections. It will also test for a blown tweeter (open circuit). A quick call to Barefaced wouldn't harm, if only to get their price for a replacement tweeter, although they're normally available from the usual sources.

First things first is play some music with cymbals in it through the cab and put your ear up to the HF driver. You'll soon know if it's working or not.

I have a very nice Avo meter that I *ahem* borrowed from work on a very long term basis.  

 

Thanks all. Plenty to go on 👍
