Volume pot in loudspeaker

[almaviva]

Hi, I am an absolute newbie in this field and I am at my very first experience. I apologize if what I am writing is a very naive question and I am thanking everybody for the patience.

I already built four loudspeakers using a single Monacor SP60x driver. The four speakers are powered by a single TAmp that receives a mono line signal.

For practical reasons that I am not going to explain, I am in the need of being able to switch on and of the speakers and to set the volume level with a "pot" in the cabinet itself, meaning that the "pot" has to be between the amplifier (that will be always on) and the loudspeaker.

What kind of component would work for this purpose? I have been reccomended to use a "L-pad" but I feel a little bit disoriented.

Thanks.

Rob

Without knowing the fuller background of your application, Yes, an L-Pad is the proper recommendation.

In essence it is a voltage divider comprised of a pair of resistors. L-Pads are rated (in watts) for how much power they can handle. These are a standard item and you can buy them at Radio Shack.

Slightly off topic, you mentioned you were using a single amp to drive four cabinets. Depending on how they are wired (parallel, series or both), it is possible that you may be presenting a difficult load (low impedance) to the amplifier.

First of all thank you.

The four speakers (8 ohm impedance each) will be wired in parallel, two for each channel of the stereo amplifier.

Each of the speakers will need to be "controlled" by a single volume pot.

Thanks for your help.
