Infinity SM-112

[carls06]

Picked up a pair of infinity SM 112 for cheap, and wondering about the single Freq Control Knob,. Is that for just the tweeter ?? Only ask as i cannot here any difference at all no matter where i adjust it to..

Yes, that would be for the tweeter only, in fact, it should be labelled HI FREQ LEVEL. Are the tweeters working properly? Infinity level controls in general have a relatively narrow range. If you're not hearing anything from the tweeter then there could be any number of things wrong including blown tweeter, disconnected internal wire, corrosion on the control or leaky capacitors.

I will recheck them, but i do know tweeter are working , but my ears dont here any change when turning level knob. But ill try and get some Deox in the dial switch

Well, the SM series are basic cheap speaker, they are a good segway but very thumpy and not that great sounding.

I dont get the thumpy part.. Bright yes

I was wrong , after checking a little more i see there is no sound out of the tweeters... So i removed them and ohm test showed they were not open.. So i then hooked up a set of car tweeters i have here and they worked... So im assuming both tweeters are blown... I was thinking they would show open with a ohm meter if bad ??

What reading did you get from the ohmmeter?

I will have to take one back out and check , as i cant remember at the moment

Well i just took the other tweet out, and test with ohm meter and that one shows open with meter.... So yes dead tweeters

I believe these are 8Ω tweeters and TBH, the stock tweeters were nothing to write home about. If you want to get them working again, I'd just put in a pair of inexpensive 8Ω soft domes.

If you're planning on selling, that may not be the best use of your money. These speakers generally don't sell for much; you might be better off advertising them with blown tweeters and a link to your intended replacements.

May still be worth adding them as they are cheap.... And there is people that actually like these speakers...
