Question about KEF Audio PSW 3000 Subwoofer

Open Question

My kef psw3000 doesn't work. The system powers up however absolutely no bass/sound is delivered when connected to an amp. I have checked the cable and amp through another sub and there aren't any problems there. Do you have any suggestions on how to fix ?

Hi i have a problem w spaker kef Q700 so has stoped working tweeters in pair spakers ,bass working , and I don't know what happen ;-(


Check the cabling. Check the connections. Check the audio source.
Check the extended warranty you added when you bought those $1500.00 speakers.

How do you connect the back cables so the sound will come out right


There are four posts - two black and two red. They should be connected together, as shown in the picture. If you are missing the brass straps, simply use wire to reconnect the posts, black-black and red-red.

Then it's a simple matter of connecting the red (+) amplifier output to one of the red terminals, and the black (-) amplifier terminal to the black terminal on the KEF.

The KEF terminals can be seperated if you wish to "biamp" or "biwire" these speakers. Each black/red pair is dedicated to either the bass or the treble. For higher fidelity, some listeners prefer to run seperate wires from a single amplifier channel to each individual speaker input.clmrt5000_5.jpg

Do LF and HF +/_ both be connected and if yes do they both go to speaker system A or separate to A and B on the amplifier.


From the factory, those are equipped with "jumpers", one for red-red and one for black-black. This allows for one speaker cable to power one speaker.

The jumpers can be removed, allowing for "bi-wiring", where you run two leads from a single amp channel to both inputs on each speaker. There's also "bi-amping", using a treble amp and a bass amp dedicated to each input.

If the jumpers are missing, you can use a short piece of stripped speaker wire to reconnect the upper and lower binding posts, just be sure to match colors.clmrt5000_0.jpg

OVERLOAD


First of all the KEF is a powered sub which means that it wants a line level signal NOT a speaker level. Send the signal from a tape output or pre-amp output to the sub input. The overload is because the impedence load for the speaker output is too low and looks like a short to the amp. Continued attempts to connect the system as described will result in damage to the output section of the amp.

Please let me know if you need more info.

How to test your speaker


Check sub buy pushing cone in gently if you hear or feel a rasping sound the sub is blown,if not check for a fuse where the power cable goes in as this may need replaced.Also make sure you have the sub plugged into the sub pre out and not the six channel input.
PS did switch on the sub in the speaker set up in the menu?
hope this helps.
