Looking for parts and service manual for Accusound AS-6120A audiosphere speakers. Also, looking for unit name of speaker front panel that got flat knobs for tweeter and midrange sound adjustments.

SOURCE: karaoke speaker,no woofer or midrange working, only tweeter

Hi, it's probably that the 8" woofer and the midrange of the "amped" enclosure is open. One way to test is to remove just one wire from the inside of the enclosure to the woofer or midrange in question and with the use of a continuity tester (or a VOM), check for the resistance of the coil of each the 2 speakers. Both should read anywhere from 4-8 ohms, if there's no reading (VOM needle will not move) then the coil(s) are open. In the absence of a tester, a single AAA or AA battery would do (pls. some would argue that this is not a sound practice, however this should be enough for you to be able to determine the condition of the coil(s)). With the use of the battery and a single short length of electrical wire, apply power from the battery to the terminals of the speaker, if the cone moves, then chances are it is good, if they don't then you would have to replace it. Am not sure if available in your area, but there are some trained people who can rewind the coil should a replacement speaker be not readily available. Hope this be of help. Please let us know how things turn up. Regards.

You probably burned tweeters and damage midranges but before disasembly check equalizer

If you have a Ohm Meter, check the resistance to the speakers. If it is very high, the speakers are burned, (or the crossover is (just capacitors, and resisters...cheap)). If it is close to 4 ohms check the wiring and connectors..to and at the speakers, most likly the receiver/amp is not blown.

Press the audio button (A button in right hand upper corner) till you see FADE or BAL press the up down or left right arrows to adjust the fade and balance till all your speakers work.

If they still dont work, check the wiring at the speaker and the wiring behind the head unit to make sure their properly intact and properly grounded.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
