Is it possible to L-pad an L-pad?

[jaencer]

I built a 3-way speaker, and my midrange driver is too loud by a couple dB. The box is all sealed up :-/. It already has an L-pad on it for -3dB, but needs another -2dB or so off. Can i add ANOTHER l-pad to it, after the first, to achieve -5dB????

The pic didnt work... But its basically two l-pads connected to eachother, one kills 3db off 8ohms, then the second kills 2db off 8 ohms...

nobody knows? two l-pads on one speaker? possibe?

Your post is nonsense unless you decribe what you are trying to do.

What do you mean by L-pad? Do you mean a commercial L-pad, the ones that are basically a big variable resistor? Do you mean one made up of 2 resistors? Why did you use 2 resistors designed for -3 dB when you needed -5dB in the first place? Did it come preassembled on a commercial crossover?

yes you can, but it makes more sense simply to replace the original L pad

A couple of points -
... you need to use the ACTUAL impedance of your drivers at the xover frequency, it seems that you're using nominal when you say '8 ohms'....

...if you need to use an attenuator on the mid, you probably haven't chosen a woofer of suitable sensitivity... you could gain the extra lows required by adding another woofer...
