variable l-pad with 6 ohm load

EdGabriel · 21st October 2006, 04:48 AM

Pardon the newbie if this has been coverred, but I could use some help.

I would like to use a variable l-pad for a 6 ohm tweeter. I can find 8 ohm l-pads. I understand that a stereo 8 ohm l-pad can be wired in parallel for a 4 ohm load. But what would be the best approach for a 6 ohm tweeter?

Thank you!

Hi,

an 8R L-pad should work OK with a 6R tweeter,
though it depends on the exact crossover details.

Thanks for the reply!

My intention was to use surplus JBL L100t3 crossovers I own, but bypassing the existing fixed lpads on the xovers, and using the variables.

I'm going to have to rithink this, however, as using the 6 ohm tweeter would also require my making other changes to the crossover.

I guess I will either select a different tweeter, or build the crossover from scratch.

Thanks again!

Hi,

On a simplistic level simply put 2R is series with the tweeter.

But many 8 ohm tweeters measure ~ 6R DCR.
