    thanks for that, i've check continuity on the speaker which it has and also worked it from another stereo, so the problem is somewhere in the amplifier part of the unit, it has a small fuse inside which is ok.

Probably blew the speaker or the crossover coil. You can check it with both with an ohm meter to check for continuity. Disconnect the speaker and/or coil for the rest of the box before testing.

Kef htb2 subwoofer not working plug fuse ok sub fuse ok is there an internal fuse


If you have external fuse there will be none internally. Chances are you have blown the amp if power is confirmed to be getting into the unit and there is no sound.

It's not clear if this has EVER worked or what is new in the scenario. The STR manual has setup instructions for supporting a sub. If you want to prove the sub itself works you could jack any source like, say, a CD player, into it to prove its amp will respond BUT IT WILL BE LOUD if it works.

I do not know how to connect the woofer KEF PSW3500 to the amplifier Denon 4310. BCC sold me a 1 on 1 plug, but the woofer needed to plugs (left and right).


Bass is mono directional in the main,and while your sub has a left and right input ( because a few amps do have left and right sub outs) only one of them is required (usually marked as MONO on the sub). You can also get a Y splitter phono adapter and connect the single cable you have to both sockets, which is how I have mine set up. This is most common

Im having trouble with connections from kef psw 1000 sub to onkyo tx sr506 amp. sub is making a bit of a humming noise but not getting any proper sound through. dont know what im doing wrong. can anyone...


Have you got the sub defined to the Onkyo correctly? Try conencting the sub's input to one of the Tape Out connectors and play some FM through it. That will prove if the sub is alive. The nwe can troubleshoot the correct failing device.

Loud buzzing from Kef PSW1000 Subwoofer


yes. A good idea. Kill power to the sub, then unplug and remove everything from the sub. go ahead and plug it in again and check for buzzzz.
That is test one. if you have buzz still, its the sub assembly. bad luck, but not impossible. If the buzz is gone its one of the signals to the sub. They can produce a buzzz without any signal coming from your stereo equipment. Replace the feed line, enjoy! BTW...Kef sure does sound clean. good choice.

HI,go into the yam setup menu and make sure you have the sub turned on and cross over set to about 80hrtz if this suits your speakers,set sub level to about -5 on amp and say half way on the sub,this should work if not pull out sub cable at amp and touch the end,you should get a hum,if not you may have no power,faulty cable or sub.
PS>make sure you are pluged into the sub PRE OUT and NOT the six channel in.
Hope this helps.

Clestion S10 Sub not working


Instead of connecting it to the sub output, try it on the L or R output of your amp.
This will eliminate the Denon.
If this fails, you need to test the loudspeaker driver unit whilst disconnected from the sub amp. Use a 1.5v cell (AA or bigger) connect using croc leads to the speaker's terminals. If the speaker is OK, you should hear a click. If you hear nothing, the speaker unit is faulty.
