    ADS L780/2 Mid not working. Please help.

    Hey, Guys. So I'm working my way through this x-over, but I'm not sure if I'm figuring anything out. There're two 11uf caps, two inductors and a resistor on the circuit for the mid. 1 cap and one inductor on the way to the mid and 1 cap, one inductor and 1 resistor on the short cut back...

    ADS L780/2 Mid not working. Please help.

    Hey guys. Just wanted to see if anybody had suggestions on how to test the individual channels or whatchamacallit on a crossover? I'd like to narrow down what part of the board is giving me trouble. I don't have access to the other crossover right now. It'd be great to be able to swap the...

    ADS L780/2 Mid not working. Please help.

    Thanks for the advice. I tested the wiring from the crossover to the driver separately. It's still good. I'll try testing the individual crossover components and see if I can figure it out that way. Does anybody have a schematic for the crossover?

    ADS L780/2 Mid not working. Please help.

    Hey, guys. I have a pair of ADS L780/2 speakers with a problem. The speakers are in great shape, but one of them has a mid not working. I tested the mid, and it's still working. It sounds fine when I hook it up directly to a receiver. But when I connect it to the crossover it's not making...

    KEF C75 Replacement Tweeter?

    Hey, guys. I've got this pair of KEF C75 that need a new tweeter on one side. Where's the best place to get these? I see a few on the 'Bay, but is there a better/cheaper/more reliable source?

    HK SUB-TS14 - Not Working

    Thanks for the manual. I actually found that whilst googling around a bit myself. I didn't find anything much like my issue in the troubleshooting section though. I don't have the rest of the set so I wasn't able to try it plugged in. The thing that threw me is the time it worked for...

    KEF C75, Sound bad and getting worse?

    Hey, guys. Got another speaker question for you. I recently got a pair of KEF C75 speakers in to look at. I was told that possibly one tweeter was bad. I plugged them in to test them out... They sounded terrible. Muffled and dry and lame. Then, as I continued to listen, I lost all...

    HK SUB-TS14 - Not Working

    Hey, guys. I have this cool Harman Kardon sub I'd like to get working (SUB-TS14). When I got it, I was told it didn't work. OK, fine. I'm game to give it a try. I flipped the power switch just to see, and no smoke or sparks. Just an amber/yellow power/indicator light up top/front. I...

    JBL LE14-1, Refoaming Turned Up an Issue

    Thanks, guys. So it sounds about like what I expected as well. I'll talk to the guy before I take off the dust cover, but that's what I figured would be the next step as well. I'll let you guys know how it turns out. Thanks!

    JBL LE14-1, Refoaming Turned Up an Issue

    Hey, guys. So I'm refoaming a JBL LE14-1 for a friend and have run in to an issue. When I started the inner lip of the foam-job, I noticed that the cone had settled way below the zero position, and was kind of "stuck down". Almost kind of wedged down, just slightly. I didn't think...

    Replacement Mid Driver Suggestions for Speakerlab S60?

    Hey, guys. I'm working on restoring a pair of speakers for a friend. I just did surrounds on the 8" and 10" drivers, and when I went to clean the old, slimy diffusion material from the mids, I noticed they were both blown. Seems that they are "Polydax HDM 8 ND" drivers. Paper cone, 3...

    Help removing trim for refoam on Infinity RS 325, Please

    Hey, guys. So I have this set of Infinity RS 325 speakers here and they need a foam job. I can't figure out how to get the trim pieces off the drivers though. I'm sure they just need to be pried off, but I really don't want to break them. Any suggestions? Thanks in advance, guys!

    Need a little help with a Nakamichi CDC-3a CDP...

    Hey, guys. I picked up this CDP at a thrift the other day, but I can't get it to spin up the CDs. Do any of you guys know about this CDP? So I put in the CD, then it'll slide it back to the spindle, and the spindle will give it just the slightest little turn, like maybe 40 degrees. Then...

    Werd woofer problem. Leads coming loose?

    Hey, guys. So I didn't want to go to the trouble and expense of cutting off the dust cap, so you know what I did… I just glued the lead to the back of the cone. It worked fine if it was in just the right position, so I just put a dab of glue on the lead and that seems to have taken care of it...
