Question about Acoustic Research S112PS Subwoofer

Blowin resistor on my Acoustic Research S112PS

If anybody has there speaker apart I am trying to figure out what size or color code the resistor labeled R159 is. The one in my board got really hot and fried. The colors are to faded to see and using a ohm meter is no good because the resistor is fried. Other people who have a problem with the amp might want to look at that resistor. It is a cheap fix if you can figure out the resistor value. If anyone can tell me the color code or value of that resistor I would greatly appreciate it.

When I put an ohm-meter across it, I get 505-ohms. The color code looks like maybe green, dark brown, brown? Mine is discolored too. Green, brown, brown would be 510ohms. . .so that must be it. The tolerance band is gold, so that's +/-5% so that would explain the 5 ohm variance.

I have a pair of acoustic research "active partner" speakers in need of a power adapter. Above the entrance of the plug in print it has DC 11.5 V. Need a compatible adapter.


DC 12v adapters are common and I think that would work. The similar "Powered Partner" speakers used a 14v DC adapter. Just check the size of the plug and the configuration (center pin is +). Radio Shack and other sellers have universal adapters.

Well I also have a S112PS AR Sub Woofer Problem...


Are you sure it is receiving an audio signal to make it wake up? You don't mention what's upstream in the audio chain.

To eliminate mis-settings or lack of sub-related signal upstream, plug an RCA cable from a CD player directly into it and start a CD that fades in slowly because you won't have any way to lower the volume except to pause the CD. If the sub works you'll hear a muffled version of the program.

Hi it is green then it turn red when i cut it off it go back to green , on the back all it has it off or auto/on what to do?


Something is causing it to go into protect mode. Auto on is best because it turns on when an audio signal is recieved. A sutten surge of sound can often cause it to protect itself. If this does not solve the problem, then you might have a bad amplifier in he unit. You can often replace that amp, but sometimes its just best to replace the whole unit. If the subwoffer is bad, it can also cause the unit to go into protect.

Acoustic Research ARS115PS Subwoofer, No Sound


I have the same problem with the smaller AR 112PS speaker and since Acoustic Research went out of business, I too have been looking for a solution. I may have found an alternative to throwing away this really nice speaker. I found a company on the web that appears to sell an amp that may fit nicely into this speaker enclosure for $99.00. Check it out...

UPDATE Feb-16-2016: This Amp is still going strong since 2012 when I replaced it. The price has gone up to 139.00, but may still be worth it to replace a bad one given the cost of Sub's today.
