20 Most Recent Jmlab Cobalt SW27A Speaker Questions & Answers

Check your connections. Make sure everything is plugged in properly. If it is still making a sound, even a whisper, then the amp is probably fine. Do you have other speakers connected to the amp? If so, they should be sounding too. If not, then it's definitely an amp problem. Ebay sells tons of .... well, everything, so you should check that out...

Hello unfortunately it sounds as if the coils in both woofers are open,you have pretty much confirmed this by your direct connection however putting an ohmmeter across the terminals will tell you as well.If you have a meter the woofer should measure approx 6 ohms,if it measures 0 its bad.Another simple way to tell is with a 9 volt battery,simply connect with two wires and see if the woofer pops if not its no good.

System power is controlled by a switch on the right satellite speaker ON/OFF VOLUME control, therefore you would have to connect a separate switch to control power. However, you may be able to get a satisfactory result by turning the satellite volume control completely counter clockwise and adjusting the WOOFER VOLUME control to the desired level.

A shelf that is expected to support 70 pounds will need to be attached to the studs, where ever they may be located.
Perhaps you can redesign or modify the provided hardware or invent your own mounting system.

Anything in the neighborhood of 8-ohms will usually fly safely with standard audio amplifiers. At only 50w x 2 you want efficient speakers. Watch the volume as this amp may clip if driven too hard. THAT will kill any speaker.

This owner had Valdus 200's and was happy. But just about any quality speaker in the 100w range should work out.
