Blew my 1x12 cab speaker.

[impactwrench]

First off, here's my rig.

P/J basses (passive)
GK 400RB-III or Backline 600
Avatar B210 Delta
Avatar SB112 Neo

So I think my Avatar SB112 neo gave up the ghost at practice tonight. It seemed to semi-crap out about 3 mos ago (with the 400RB-III) but when I tested it at home after practice, it worked again. Ive since practiced and gigged with no problems. Tonight it just quit mid-song. A couple cable switches didnt help. Brought it home and I can only hear a quiet farty noise in the horn from either head, and both heads work fine with the 210 cab. I think my best bet is just replacing the 112, and I think I want another neo, since I really like the weight of the cab, and the tone is pretty sweet as a stand alone. (I like the backline with the 210 and the 400RB-III with the 112). I figure the cab is not worth much as-is (to sell used), so I cant really justify ordering an ultralight GK cab vs just replacing the speaker as the most cost effective replacement. Any suggestions on how to avoid blowing another speaker?

get a speaker that can handle more power, i believe the 12 is meant for 250 watts. I have to say im not great about not blowing speakers myself though.

Go with the 12" ceramic eminence speaker? I think it's more like 500 watts. Notice I'm not pumping a whole lot of wattage through it at any time though.

Replace with Eminence Kappalite 3012HO. Better power handling @ 400 watts and more excursion = deeper bass. As light or lighter than the Deltalite you have now.

Where is the best place to order that from? I don't think that is the one dave was offering me when I emailed Avatar. I think he just carries the deltalite.

Or how about a Kappalite 3012LF?

I would make shure it is the speaker before buying anything. Mabe you fried the crossover?

Good point, how do I test that?

Or do I just take the speaker out and check the ohmage? I have a multimeter.

i'd just temporarily disconnect the speaker from the x-over and touch a 9V battery across the 12 in speaker's terminals to see if it has an open coil or a bad connection.

+1. There's no point in fixing something that isn't broken.

[80'sRocker]

IMO, any 1x12 is simply not enough speaker "real estate" for a good sound

[impactwrench]

how can I tell if the crossover is friend? Im working on testing the speaker with a battery. cant find my multimeter.

Did you by chance run those Avatars with the tweeter knob all of the way off?

Maybe. I cant remember. I just set it and forget it. I think on the 210 it just seems to hiss quite a bit, so it is all the way down.

I found my multimeter. The speaker shows infinite ohms, so I guess its blown. The crossover is all covered in hot glue, but nothing looks burnt or smoky.

[johnk_10]

yep. infinite ohms means open voice coil, unless the tinsel leads somehow got disconnected.

[impactwrench]

ok so do I want the kappalite 3012HO or 3012LF? Is the LF only if you're using a mid driver and not a horn? What if im using the 112 cab with the 210 cab? Would the LF be better in that case?

Edit: After a couple searches, it looks like the HO is the way to go, especially since I use the cab stand alone at times. I think it's definitely better than another deltalite, since I may upgrade to an MB500 in the near future.

[Blues Bass 2]

Right , the 3012HO would be the one for full range .

Will I be the first person to put one in an Avatar 1x12 cab?

I don't know but they are fairly forgiving in "normal" cab sizes and tunings. May not be your golden tone but it will get loud and handle a whoopin'.

[impactwrench]

The cab is/was 8 ohms. Do I order an 8 ohm speaker, or is it 16 ohms since its in parallel with the horn? Or does the crossover not affect overall ohms of the cab?

For about $50 less, and adding about 5 lbs of weight to the cabinet, I can just get a ceramic Delta 12LF, putting the cab at 500 watts, instead of 250 with the deltalite 2512. I guess I have to decide if its worth $50 to save 5lbs.

Moot. Watts are meaningless. What counts is driver excursion capability (xmax).
